Volvo P2 Engine Diagnostics (S80, S60, V70, XC70, XC90) - Overview, Failures, Symptoms, And More 

Owned my R for 6 years but still learned a couple things from this video. FCP is the best.

R owner here with 276k miles on it, I’ve done a lot of these recommended repairs, more than others because it did fail. All I can say is, take care of the Moose, and the Moose will run happy.

P2 XC70 2007 owner here! THANK YOU FOR THE FUEL SYSTEM description. I have been chasing a P0089 fault for 9 months, replacing everything except the pump. About to change the pump (with help). Wish me luck!

I wish you had a warehouse in Europe, because your assortment is better than what we have in Sweden.

It's stuff like this that makes me want to buy all my parts from you guys... you guys rock thanks again!

P2 S60 owner here. Love the content, as I always do work on my own car. Appreciate what you guys do!

I can't believe I've been working on cars for so long and never thought of tying a string to the fuel sender hose. Came here for Volvo tips and left with a super useful other tip, I love FCP these guys are real pros!

Thank You FCP Euro for the informative P2 videos keep them coming .

I had idling issues with my 2007 V70. After some research, I decided to grab a can of Throttle Clearer at NAPA. I removed the ETB from the intake manifold and sprayed the crap out of it. I was very very dirty. I also cleaned the MAF Sensor with a the special cleaner for that too. One or both did the trick … It has been well over 100k miles since doing that and not issues.

Awesome video, thank you for making this!

I think changing the fuel filter is very important on Volvos. Every P2 I've ever changed the fuel filter on had black oily looking gas in it. The car wont even act like anything is wrong but that gas cant be good for the engine. I feel like they are rarely changed likely because the diagnostic tool says something else like maybe a bad MAF. Thats probably the first thing anyone should do on their Volvo if they are unsure if its been chaged, because chances are its the original filter. It's probably the easiest thing you can do on these cars and they are cheap like $30 or less. That's just my opinion though.

Thanks for the video. Everything is simple and great! Now, we're waiting for the similar video about B6294T engine )))

Outstanding video, every P2 owner should watch this!

Awesome detailed engine overview. Thanks a lots. Volvo for a life)

Great content! Thanks!

Towards the end where he talks about having to get the throttle body flashed with new firmware...it maybe a thing but I did take a TB from a T6 XC90 and put it on a T5 XC90 with no issues. Great info on all of the other P2 issues that every owner will be faced with.

Excellent information.

Awesome video thank you for making it!

Great presentation and helpful information

Great overview video, and have replaced many of these systems on my various Swedish P2 Hjoopties. I'm now getting a persistent P0302 code (2002 V70 X/C with 2.4 low pressure turbo, 175K mi) that came on suddenly last week, and swapping out the plugs, coil, and fuel injectors doesn't fix it, and I have good electrical power and connections to the injectors and coils; and it's making a pretty noticeable tapping sound from the vicinity of #2 cylinder that is really noticeable when the oil fill cap is removed. I've heard that a part of the PVC plumbing, a little v-shaped vacuum check valve pipe that connects with a banjo bolt to the underside of the intake manifold and which connects via hoses to the thermostat housing, the oil box, the main PVC hose and to a vacuum line, which, if it fails, will allow a small check valve ball and spring to get sucked down into the oil box and up into the breather hose to the top of the valve cover, and into the head of #2 cylinder, and which then gets stuck in the head or the valve, causing the tapping and the intermittent P0302 misfire code. Now that I have the intake manifold off and have visually inspected the PVC hose and components, I do see that it is all in need of replacement, which of course I will buy from FCPEuro!, but I wonder if I should also pull the valve covers off and inspect the intake cam shaft and lifters, or even pull the head and visually inspect the valves and see if there is indeed debris from the failed PVC system rattling around in the head before I replace the PVC components and put the intake manifold on and put it all together again. I have snaked a magnet down into #2 head via the spark plug port, the FI port, and the intake manifold port, but haven't caught anything with it. Anyone ever have the same problem? I'd appreciate any insights.Thanks! And please keep these videos coming, guys!

A suspension discussion would be helpful, too. Thanks! Great work!

Great and informative video!

i have 2 v70n bi-fuel models. 340.000 miles an the other 270.000 miles. engines where never opened. they have the factory fuelpumps, throttlebody's (with the white sticker),VVT pully,thermostat,PCV valve's. only things replaced are coils and 1 coolant themp sensor. i just love them. greets from the netherlands

Thank you for this video. I always try to buy parts from FCP so I can fund these videos.

Thanks for the informative video. I have three XC90's that I maintain. The PCV system is a pain in the butt -- as you say working on it is "kind of a process"!

Volvo cars of the P2 platform are quite well built so that they are easy to repair on your own with little experience

excellent

Another fantastic video guys, looking forward to seeing more! After watching this video I checked my VVT intake solenoid as recommend and the resistance was only 3-5ohms, this is at 146,000 miles. Also checked fuel pressure and it was at just over 50psi.

We need these kind of videos for the D5 engines!! : )

Is there a great video like this for the P1 models ? ( like 2008 C30 T5 )

Thanks for taking the time to explain this. If I may, a question. I am dealing with a 640A code on a B5244S non-turbo engine with one intake phaser only. I replaced an open-circuited Cam Reset Valve, which was showing no movement on scan tool. I now have movement of the phaser. BUT the Actual Cam Angle, as per the scantool measurement, is consistently about half of the Desired Cam Angle called for by the PCM. I understand that the 640A can set if the Cam Angle varions is greater than 10deg for more than 15sec? I am suspecting the phaser hub is binding or for some reason not fully actuating?? Possibly, this caused failure of the Cam Reset Valve windings as the PCM continues to try to full phase the cam by holding a maximum Pulse Width Modulation, maybe overloading windings over time. Wondering what your overall thoughts are on this??

Can you explain why some of Volvos got vvt on intake only, some on exhaust only and some on both of the cams. What's the reason behind these different solutions.

Great vid. I had the coil harness plastic all dry and crack, wire insulation melted and shorted together and caused crazy misfiring...the coil harness I believe coil 3, bends the wires so aggressively, that's where they wore through. Was an easy fix but hard to spot at first, had already pulled all coils and plugs to test. Also, having the transmission hard shifting issues showing up, but read one comment about someone who said it only showed up on 1/4 tank or less, so I filled mine full and all rough gear change symptoms are gone... 2007 XC70

2000 s80 t6.270bhp originally but now slightly modded .twin cat back stainless custom escape.51000 miles and so far only problems were the throttle body needed cleaning.top mount replacing.a couple of rubber pipes .i gotta pain in the arse water leak from the top hose which is getting to the point of hose and radiator replacing due to the age.all in all its my second ever Volvo but not unimpressed with it.engine will go good in a hearse me thinks.

Very informative! I've recently acquired an xc90 2.4 D5 awd and it tends to decide when it would start and when not to. It cranks at times, starts and many times it just sounds clicks from the relays. Do you guys have any experience with the error message "Start prevented please try again" which shows on the dashboard? I've checked all relays and fuses, there's only 1 key, I've tried the lock and unlock sequence, replacing batteries both in the fob and car itself and the issue remains. Waiting on a diagnostic to be in the next day or so but thought I'll reach out in Case someone has experience with this.

Great info. Im going to mention ABS Modules which will need to be replaced eventually.

'07 VR here. If you own a P2, change your oil religiously, and you can avoid a lot of the PCV issues.

I had a crack in my coolant reservoir cap. The bottle would boil after shut down. Replaced with a new cap and all is back to normal.

I love these kinds of videos. I would also really like to see the p1 engines as well

Thank you.

The P2 PCV system is the biggest antagonist to what could have been a beautiful engine. The idea could have been salvaged by Volvo acknowledging the flaw and correct it with properly designed parts and also sell the parts at reasonable price. Currently, buying the 'flawed' PCV parts is as painful as getting poison ivy. The labor to get the job done is just as bad. The electronic throttle body is another pain in the butt! I've learnt not to trust Xemodex for one as a replacement. I would either bite the bullet and buy a brand new one or get a used one from a yard. Turbo model to turbo model. N/A to N/A would be fine without software for my experience. Whatever it is, i would steer clear from Xemodex at all cost. This has been an excellent video Bravo FCP! Buying from FCP makes a lot of sense.

Volvo tech Rock Star,

Great stuff! Congrats on the initiative! Any material planned for the diesel engines?

can you please show me how to replace the batteries of remote key for Volvo 2007 S80

It's amazing how there is a familiarity to the sound of a Volvo engine as it idles, even over different engine designs. I have been driving Volvos since 1970. Also, are Volvo dealership service departments willing to provide technical information for the DIY market these days? The last time I needed a part number for a 90's vintage 740 motor and I called the nearest Volvo dealership, the guy who answered the phone in the parts department just said: "Can't help you."

Hi, I have a quick question. I recently got an 05 Xc90 from my Dad. He didn’t want to deal with the repairs that needed to be done on this vehicle. That being said I recently replaced the fuel module and the fuel pressure sensor on it. It run nice for a day and then it began to burn the fuel pump fuse and it’s driving me crazy because I don’t have a clue what is causing this problem. Please help!

I have a p2 xc70 2005 with 132XXX miles that has bad engine shaking lost of power and fuel economy and this problem worsens when the a/c is being used. I've read this all could be because of the coils and plugs needed replacing. All the plugs were replaced with volvo plugs and 3 coils thought to be bad were replace and this is still happening. Im hoping replacing the last 2 coils will solve my issues. Is this all that can cause those symptoms or am I being to optimistic??

Check out our Volvo P2 page here: info.fcpeuro.com/p2

A couple of things you didn't mention the fuel filter at about 96,000 km should be changed. And if changing the fuel pump access is from top of tank via lifting out the back seat. And a special tool is needed to remove retaining cover over the pump.

Can you make a similar video about p3 chassis volvos? We would really appreciate that. Thank you!

Hi on my 2002 Volvo V70 I replaced the rear crank seal transmission end but when I torqued up my flywheel bolts it rotated clockwise I didn't think much of it but when I reassembled the car I started it up and it only ran for 7 second,s and it stopped Suddenly like the cambelt had snapped but the belt was tight and the tenchoner was tight and i turned the engine over and I've no compression and I then removed my timing belt and the Intake Cam feels very loose it pulls out very easily does this happen to V70,s mine is a 2.4 non turbo take care

What... No mention of the redheaded stepchild? Also known as 2.9L T6!! Thanks! 🤔

Are there any known issues regarding the oil circuit. The oil pressure light, and things like the oil pump and the pickup in the oil pan

I have a regular V70, no particular version but it's very reliable. It's around 210,000 miles (approx conversion). The brake lights are janky (not lighting up when braking but the top works perfectly) and the inner rearview mirror is loose.

Love this video just wish for the parts used in this video could of dropped some part numbers on small print.

Excellent video as usual. I have been a FCP customer for around 20 yrs! I won't go anywhere else for my Volvo parts. I wish you would carry Subaru parts though. How about a concise Vida tutorial. I need to learn more about the advanced functions.

The torx 27 valve at the end of the fuel rail... what exactly does that do. I think i cut off fuel supply somehow. I have new pump and new sensor and im not getting any fuel at rail.

Glad to see that Adam has found greener pastures after eEuroparts went bust.

Hello, is it safe to drive a 2001 Volvo S60 non-turbo with a replaced throttle body, without it being programmed? Will the car be damaged? Thanks love your videos

Any chance theres going to be one regarding the B8444S?

7:49 FYI they are oil galleries not galleys.

Really helpfull video! Mine is a 99' 2.4 NA 2.4 S80 with AW auto gearbox. Got it with 90k Km. Idlle goes to stall once the engine is warm, when I release the throtleit wil go down to 200rpm and even stall. Can't locate the problem. Oil was bad due to loong time (not miles) between changes. Crank case presure is ok. I'm going nuts

Did I miss the section on potential oil leak locations?

5:56 we have found a great replacement seal from a specialized o-ring company What’s the link to that green o-ring part? Any videos to link to it?

Do one for the D5 :)

Great vid but can we have a diesel version of this video for 2010 + cars v/xc40 s/xc60 v/xc 70 s80 xc90

you can get fuel pressure reading from obd

The PCV BOX comes in 2 different types...Are they interchangeable??? I have 2004 non turbo, this is not a rocket science to solve but I prefer an after market even if I have to do the plumbing to which it would be easier to clean the box...

Looking forward to a P3 version of this

That fuel computer can also be redirected towards the inside as I did it’s a bit of a hassle but possible.

Great video, will you be showing the P3 some love soon?

V70 T5 - B5234T3 engine please🙏 really need closed tutorial

I have Volvo s60 2.4 petrol, 170hp, 230000km, 2001 yrs. Bought cheap, 750 euros.. Nice design, comfortable seats, great engine sound, decent acceleration! But have some major issues: 1. check engine light is on with report 'emissies service vereist'. 2. steering wheel hydraulic pump have noise, 3. front wheel bearing very loud when driving.. planing to change i hope soon..

Can you tell me details on my volvo s60 t5 its a 2.3L petrol turbo I believe is this engine good??

i dont know what the P2 engine is, is it the T5 that came in the 850 and later generation or those he mean the straight 6 that came in the 960?

So how do you prevent the PCV system from clogging in the first place ? Thank you.

Is this ALL the common fail engine items for the P2 RN engines ? Anything else ?

Can I get black v70.i love to drive. Awesome

I got a 2001 volvo v70 xc turbo... when i did the saprk plugs a i found the spark plugs has a lot of oil...

Can you Swap a V70 High Pressure Engine into a 2006 2.5T XC90?

Is it possible to clean the PCV system without replacing almost all parts?

Good information I have 07 r

Can you do a video explains the “R” I have a v70r and would love to know more of the history. I use to have a 850r also so would love to learn more! Even maybe go into how r design and r are completely different so people finally stop saying they have a r when they don’t 😂

Wait I thought the 2005 Volvo s60r is non interference engine so that doesn't apply if that is a issue with the valves clashing with the piston?

I cant find any part to my s60 T 180hk 2002 Mod on your site :/

I love these Volvos but I'm glad I drive a SAAB.

Nice ! Would you do a overview of the V8 ?

So are these things the same for 2.4D?

Ive had 2 s60 t5 and around 100000 miles on long journeys i got a problem with both of them where all the electrics would fail and would skip gears

My high-mileage B5244T3 suffers from stalling while idling, uneven idle and uneven power under acceleration. When I disconnect the exhaust valve solenoid the idle problem goes away and acceleration is better, but the car still shuts off rarely on idle. I'm guessing I need to clean/change the solenoid and something else too?

Is your statement true at 2:42 that the RN engine comes with a forged crank and forged rods from the factory? On all RN engines not just the "R" engines? Block down are these engines all the same it's in the head, turbo, injectors and tune that the LPT engine is different from the HPT engines?

Volvo says timing belt change interval= 112000 miles or180000km, and it can do easy do 100000 mile or 160000km, but indeed the idler pulley is the weakest point not the tensioner. I have changed the timing belt 3 times, 2 times on my previous s60 and 1time on my current s60

Good video, but you forgot to mention probably the biggest flaw of these whiteblocks; the oil O-rings between the oil pan and the lower block. They tend to deform and this will cause an oil pressure loss (and will ruin your engine)

What's that spinning thing in the background in that glass to the left of the handsome presenter

My car not staying running what do u think it is?

Why is s60 t5 not acknowledged when talking about the high and low pressure turbo models

Having a problem locating my PEM under the car It's not in trunk it's a 03 S80 2.9l

11:50 If you're good with soldering I'm sure you can crack open the assembly.

but no mention of the 2.3 T5....

i dont think s60 have overheat problems. mine were ok temps when outside temp was 37 celsius. half way only of the temp meter
