i had the same issue two days back when i was on the road and the car just died, i didn't even noticed except when i placed my foot on the accelerator and felt that its not responsive. i took it to a car workshop and it turns out it was the "Fuel pressure sensor" however it wasn't just that, on top of the sensor it created an electric short that damaged the "ECU" luckily wasn't major and that also had to be fixed. i paid 200$ to fix it. i gotta mention your video made all the difference thanks a lot.

I have done 100s of these under the recall they had. I got down to doing the whole job start to finish in 20mins.

This is EXACTLY what is wrong with my 2013 IS250, this helped very much thank you. Cranked up without fuel pressure sensor plugged in. Have appt with Lexus to fix, this helped avoid all the diagnostic fees, thank you!

And this was exactly the problem with my car no one could have figured it out thank you very much

Hey yo! I was able to cut my diagnosis time by doing this procedure. Confirmed the shorted sensor. Thanks bro.

I dont even have a lexus but all these comments about you saving so many cars is super exciting! Good job!

Bro! Thank you so so very much! Have a shop and have spent 6 hours and could not figure this out. You are incredible! Really do appreciate you man!

My IS250 has the same issue. Did exactly what you mentioned to test sensor. Ended up buying OEM sensor from Longo Lexus in El Monte CA for $270. Swapped spark plugs also. Thank you for sharing!

Bro u saved a Lexus from going to the junkyard !! Lol I don’t like arguing with mechanics and they told me all types of things I did that fried my computer ... I saw your video and found a crashed Lexus at the junkyard .. popped the sensor off then swapped it on my Lexus .. FIRED RIGHT UP !!!!!!! THANK YOUUUUUUU!!!!!!!

Thank you for taking your time on helping us out. This sounds exactly like my is250 issue right now. Tried your method and my car cranks by unplugging that harness. Will look into a fuel sensor. Merry Christmas 🎄 🍻

I appreciate the help .. was able to fix my 07 is250 .. thanks to your info

Thanks Oz, we were going to guess this part but now we have confirmed it with your help. Your work is much appreciated. Steve from the real OZ (Australia) ;)

Excellent video and a big help to us other mechanics out in the field.

Thanks for the info!!! I have 2008 IS250 194k miles with the same issue. I used your test and it worked perfect. I ordered a new fuel pressure sensor from amazon for $20 and removed and replaced it in an hour. Thanks again.

Thanks man. Definitely made that a quick diag. For guys with smaller arms, I was able to reach behind the surge tank and unplug the sensor to verify without removing anything.

That is a fantastic video which save a massive amount of diagnosis time.

I have this exact same problem but for a 2007 Toyota Mark X, I live on the Caribbean island of St. Kitts.....many in the US would not know about this car as it was only produced for the japanese market but they pretty much use the same engines 4GR-FSE and 3GR-FSE as the lexus IS and GS family....i wanted to show my mechanic where the sensor is becuase its hard to find one on youtube with a Mark X doing this.....many thnaks :) !!!

Spot on. Just didn’t have to remove much. Replace fuel pressure sensor.

Thanks for this video,what happens when a lexus is250 dose not fire at all

At what mileage should I be concerned about this (07 Lexus IS350) Fuel Pressure Sensor going out? I'm seriously considering just replacing it before it happens to me! Thanks for sharing this information.

Hey Oz as usual spot-on! Great analysis! Thanks for all the heads-up work! Saves us lots of time!

They said my engine seized. In reality this was the fix.

Very intelligent diagnostian we love you meeeeen! (O Z) thank you. Habib Auto all day way from Ghana Accra West Africa

as i can tell by the comments this seems to be a "universal" is 250 pluage !!! well, you saved another one today! thank you. i recently started a simular channel here, this is what its all about! hopefully one day i can return the favor,. after thity five years in this buisness i have quite a few videos to make !!

Nice job! Thanks for the heads-up! I just now ran into this issue

Thank you Oz. Good job. I appreciate your videos. Have a blessed and safe week.

Does this also include the engine start/stop indicator push button not lighting up when the button is pushed. Nothing at all happens when I push the button. I have power.

Thanks Oz,, for sharing all ur hard work,,, have a great day

Spot on man just saved me a ton of time much appreciated

Good to know gracias for the heads up. Clearec po448 now have po447 has to be a pro lem with the pcm. Tryed tracing out the evap signa. Wire b134 #13 wire gave up 2006 subie sti going to dealer then getting rid of car subaru no mas no go

Had this issue, fix it today. Thanks for your help!!!!

Thank you so much you save my day and solve my problem with this video

I have a question. If you went as far as testing power and grounds why didn’t you just check 5v reference? Just trying to learn not acting like I know everything just questioning. Seems like it was guess work/ experience that found that and not necessarily diag. Don’t mean that rude but over internet is difficult to explain. Lol

I really appreciate your video, you saved my day .....Thank you

Thank u 🙏🏽 very much dude, u saved my life. I spent half a day trying to figure this out. Thank God I found your video.

Thank you so much for sharing this video. it really helps.

thanks for help

If I replaced the sensor and it still doesn’t turn on what is the problem I got p0087code

I owe you $100 maybe you have to share it with Keith this car kicked my ass for 4 days the ecm got all the power and grounds but no comm. then I stumbled on this video and viola its fixed. when I see I will give you a $100 half what I made. thank you Oz

Wow just excellent, great job!!

Thanks you for you help I have the same problem

Gracias brother por la ayuda Dios te bendiga siempre desde Houston tx gracias

No start, no crank, no communication with the Engine Control Module (ECM) and the check engine light doesn't come on when the vehicle is in accessory (Key on/ push in). Need to replace 23280-31020, Fuel Pressure Regulator. this problem also applied to Lexus IS350. Basically, fuel pressure sensor shorted killing 5v ref. Sensor connector is behind left rear of intake. To verify you can disconnect the fuel pressure regulator, engine now from no crank will crank (but of course no start) Reply if you fixed this no start.

Exelente diagnostico gracias

If I replace that fuel pressure sensor do I have to put a new gasket on the sensor? Or not? Please someone help please thanks

Liked and subscribed, Thanks for saving my morning!!! Your good you!!!

I’m having the a similar issue. No communication with the ECM I know I had an oxygen code pre existing is it possible 02 sensor shut down the network and I’m getting a no start no crank, when I go to push the start button the ignition lights on the dash turn off immediately. And scan does not communicate with the car.

It is a good video, I bought the censor and did not included the gasket and not any autopart have it so what material the gasket is made out? What are my options? David.

Thanks for sharing, you are the Man,

Thanks Bro! Was exactly my problem!

Wow what a great video thanks 👍🏻

Great video/diag Oz. Definitely an interesting one. Haven’t ran into one as of yet. No comms can definitely get interesting. Thanks for sharing. I’d have to look at the diagram. But you mentioned you had good power and grounds. Good comm coming into the PCM but nothing coming out. Would’ve been great to see some captures.

Thank you sir and God bless you 🙏🙏🙏🙏🙏🙏🙏

Thanks again good video brutha

Great tip!! Thank u!!

Have a 2006 is250 and no power, no display, question as my computer bank is slightly different from that show in your 2007 model. Also if battery shows 13.8v but no power. Checked the fuse bank no issues either.

Yup! This is mine and the same issue. O7 IS250. Want do shit plugging in, not even turn over. Unplugged from the ECM it will turn over but not start so I know this is it.

Really helpful appreciate it and subscribed!

i think my 08 is350 has the same problem, sent a video of my problem to a buddy of mine at toyota and he said that they had a lexus who had the same issues, they thought it was the ecu but after a while they figured out that it was the fuel pressure sensor

Hi. My car was not suddenly clear. After referring to the repair shop, we found that the engine computer has burned and the relationship between the computer and the car starter was cut off. After checking and repairing the computer again, the same happened and the computer was again damaged. The reason for injury is not yet specified. Please help.

Will dashboard light up if fuel pump sensor dosent work???

Thanks for the vid!!!

IS this relevant to the 2010 RX350 vehicles as they went to jump start it, car had been on used car lot from Auction for about a month then they went to jump start as mentioned above. Replaced 4-5 fuses in underhood fuse box and have to go back to check fuse panel under the dash as still have no comm on the dongle scan tool but able to pull codes using a wired scan tool but alot of active & also history codes for "lost comm" or "no comm" on alot of modules. I've identified one potential fuse under dash I need to check. Also there's a aftermarket valet switch for a aftermarket remote start system that's installed but they said the car fired every time prior to this. I'm thinking with so many blown fuses that they potentially hooked up jump box cables backwards or it has the issue in this video. LMK your thoughts in regards to if this vehicle has this known issue with the fuel pressure issue that could be causing no crank no start and the no comm issues.

I can’t get the the computer part to test it? Can’t get the blue part out above it. Any tips? I don’t wanna yank it so hard I break it.

Hi brother, so I took off the señor plug from the box and it started to crank but not turn on, can this be a confirmation that it’s the actual sensor? I’d appreciate the response

You just saved my asss i tell u that i disconnected and it cranked

Man I changed it and still does not want to start

Could it also be the fuel pump? Because I smelt gas burning in my car before and it would take a few seconds to start

My 2008 Lexus is 250 123k miles. I push the start nothing happens, does not say no key detected or anything at all. I can turn my headlights on and i can lock and unlock the car with masterswitch. i can honk the horn. but nothing else. I tried to disconnect ecu but still nothing

When the sensor knocks out the parent device, something is wrong with the engineering design. One would think that the design would insulate the computer from overvoltage in the line, individually shutting down the sensor circuit before crashing the computer. In this case I don't know how you knew the lost 5V reference was a cause rather than a consequence of the problem. I keep seeing disconcerting examples of that. Checking power and ground isn't enough before condemning a module or computer....

Hi brother, what year is this IS250?

Nice one so helpful

Thanks

Good video..this sensor fixes code P0087...on a 07 lexus is350 also?

bro thanks for the help

Nice work 👌

Thanks 😊

Hey. Anyone has any advice for me or suggestions?..I have a 2010 lexus 350gs..changed the alternator..engine doesn't start up...battery works. Power windows..sunroof, horn..engine just clicks...

I replaced my fuel pressure sensor and still no start 😭

I have the same issues but mine didn’t start working after unplugging that part ?

Mine is not starting but the check engine light is on and its saying throttle actuator control motor would that cause it not to start?

Does anyone know where you can get the washer to go with this part? My lexus dealer will not sell the sensor or the washer, only the whole fuel rail assembly @ $900. Also was told they would have to remove and replace the fuel injectors as part of the repair. Does anyone know how to get just the washer? The sensor is the only thing that's bad. It's ridiculous to have to pay $3000 just to replace one sensor.

are these common on the is350 by any chance ?

I have same issues with 2007 ES 350 Please help. Car is dead no massage when I push the button

How do you how do you change a starter in that

I did this on my own car and it worked! But for some reason now my interior lights and garage opener don’t work and I have to keep resetting my driver window. If you know anything please help me solve this issue. Thanks in advance.

Hi Oz, just got my car repaired with this issue and labor alone cost me $800. You reckon it was a bit much for the cost of work for it? Thanks!

Son-of-a-gun. Who would have thought a pressure sensor would bring down a PCM.

My 2008 IS250 has problems when in heavy rain. It starts but will not drive, will not go into gear

Does this fix P2009? Or P2017? Just wondering if it’s related

What is the name of the piece? Cómo se llama la pisa ??

I currently have this issue, thanks for sharing. I wonder where I can go to get this fixed or can I do it myself or can I order the part on ebay ?? I have a 2006.

What about a 2006 lexus gs 300 same issue

That solve my problem

i don’t have any codes popping up, before it was check vcs and it was a wheel speed sensor, then last night i tried starting it and you hear a noise under the hood. and the fuel pump turn on. and the lights that are on are the battery & check engine like that’s it.

My Lexus wouldn't start, although green led was on, turned out the immobilizer was engaged and just had to reset it.

Would this also apply to a 2010 is250 that cranks but wont turn over and the fuel pump is fine?
