Crankshaft Position Sensor Chevrolet Silverado 1999-2007 

Ben Saunders LOL

@Val Bigfish Thanks. I had to sell it last year. My issue back then turned out to be failed torque converter where the slow acceleration got worse within a few days to the point of complete failure. The transmission place in Lakewood that rebuilt it replaced 1-2 known weak parts with better, sturdier compatible parts from Corvette It ran way better afterwards. That was the only thing I had to have done. I never regretting owning it during my 15 year ownership.

Didn't have a 4x4 version available. Thanks for watching!

that was said in the video

skycam321 Look at lower left for the first solid minute. Border says to disconnect battery.

did you read that in the post that he states to remove the battery post , read it

no most likely the ignition module in the distributor under the rotor

eddie gomez I suspect the oil leak is because of a faulty O-ring on the sensor. ;P

Yes

Always a good safety tip! Thank you for watching!

Good tip! Thanks for watching!

10mm. Starter mount bolts are 13mm. 2004 Chevy suburban.

thank you for the comment

I'm glad 15 shims didn't fallout when the starter was removed like cars in the 60's.

@@williamjones7316 I busted the nose off a new high torque starter inside the bell housing on my 85 K10 blazer, cause those damned things! Glad we ain't gotta deal with those anymore! Still love my oldies though!

+Hugh McGee Sorry for the confusion but in general if you have a heavy duty vehicle it will not be the same as the regular Chevrolet Silverado. All of our videos with the HD in the title are performed on the heavy duty trucks. As for your question to replace a sensor, you have to "pull the motor" sounds very extreme.

2carpros, you guys are misinformed. i have a 06 yukon denali xl and an 04 tahoe. my crank positioning sensors are in the back of the block next to the oil sending unit

you have to pull the intake, or remove the oil sending unit so you can get enough clearance to remove the 10mm bolt holding it in. should only take 10 minutes to do

That's because the 8.1 ia not an Ls series engine. Its based off the old big block chevy engines. Almost nothing on it is the same as the Ls based 4.8, 5.3 and 6.0

Thanks bud!

PearsonFire I was just in there. It's not impossible but is a pain. Much easier if the pan is out of the way.

Just did this yesterday , wasnt as easy to just find a place for the starter. Had to take it out, over all was easy enough .

It's very difficult on the 4x4. You barely have room to manipulate the starter, because the dipstick tube is in the way. The pigtail on my crank position sensor was short and tied into the harness with the starter wires. Being short, pushing and manipulating the starter, pulled the wires out of the plug. The replacement pigtail has three gray wires, and the originals we're colored. Now which splices to which wire? Have to do some more research.

It's easy guys move that bolt in your way out I just pulled out of and shifted backwards it slides right out

Nope. No need

@@charleslentz8678 yes there is a need to do the relearn

that is not the starter or crank sensor it is something else , something is loose that is cutting out your motor , bad wire somewhere , fuel problem , ck into it

Do you need to leave 3 mad comments about the music though? Thanks for watching!

were is it at?

TheJaniceLee66 on the bottom of the motor under the spindle. it's a pain to get to and unless u remove stuff it's a one handed job lol which means u have to pull the pigtail with one hand and remove the cps with one hand. that's easy enough lol but putting the new cps in with only one hand is another animal. hope this helps.

On 2001 Chevrolet Silverado 1500 LS it is behind the Starter on the Passenger side of the Vehicle. Same for 2001,02,03 Vehicles. You must remove the Starter to get to it.

It most assuredly IS accurate Huck Finn. I own a 2000 extended cab Silverado LS 5.3 2wd and EVERYTHING is ABSOLUTELY the same

Anything that needs a spacer should not be used we recommend oem replacement parts only for overall performance and quality. This is a difficult video being the position of the sensor but we will do better in the next video with lighting. Thanks for the comment and please subscribe if you haven't already.

😂😂😂 That's me Captain Block Head! 😂😂😂

All the LS engines are this way. Same spot. We just did a full 5.3 build up and it was in the same spot. Thanks for watching!

I'd replace it again. You might have gotten a broken one out of the box. Thanks for watching!

@@2carpros that's a certain possibility thanks yes I just got a new sensor even the rubber ring is blue the one that I installed is brown I know it can be any color but what a coincidence that when I look online the one for my car has a blue ring and not brown

@@2carpros thanks a lot for responding cheers

So did you have to relearn the CKP???

It should be all good when you start it up. Whatever re learning it will do it will do on the fly with the new sensor. Thanks for watching

Actual yes you do have to perform a relearn on the newer models they don't just figure it out on their own it won't run properly until the pcm and ckp agree with each other

@@2carpros I don't think you know or understand what a relearning process is, you should Google "crankshaft position sensor relearn" before you misinform people like you have been

Didn't need it for us. Just plugged it in and it worked. Thanks for watching!

No...under distributor rotor...5.7 vortec..video is of a gm 5.3-6.0 v8

in the back of the block next to the oil sending unit

Nice! Thank you so much for watching!

It is a plug in a play system. Just replace the sensor and you are good to go. Thank you for the comment and please subscribe if you have not done already.

Did you ever get it it fixed? My did same exact thing. I ordered new fuel pump and new tps. But since I'm in there might as well buy new cps. Mines a mid year 99/00

@@Ryan_1997 I replaced the both crank and camshaft sensor. Nothing. I then replaced fuel pump and still nothing. I had 3 mechanics come out and they narrowed it down to the oil pump failing. Engine wouldnt start because no oil pressure. Basically a 2000$ job. Amd might as well replace timing while you have to cover off

@@imperialbeach3183 thanks for reply. 🤘

Thanks for watching!

Well they could include all the facts like that a relearn process needs to be done after replacing the sensor

Should be on the side of the engine block or on the bottom of the timing chain cover! Thank you so much for watching!

joncabana1 All I know is that its in the front of the engine. Near the bottom.

joncabana1 You can look forever and you will never find it. It does not have one

joncabana1 I have a 98 5.7 and mine is in front at bottom , didnt have to move starter

Harold Roach That is why this is for 99-07 Gen III motors where starter needs to be removed. ;)

Mor Bid my bad..I thought he was asking about a 1994

Yes it is, thank you so much for watching!

Where is it located on a 2007 classic?

Did you have to relearn the crank sensor and where was it located I have an 05 Silverado with a 4.8 v8 thanks

yes is does

becasue if you heard him he said it was bad and he was going to change it and decided to change the sensor while he was at it . pay attention

It is good to go. Thanks for watching!

Double check the new sensor against the old one to make sure it is the same and not slightly bigger. You would not believe how often this happens. Thank you so much for watching!

Should be super similar if not exactly the same

Should be really similar, thank you for watching!

you have no idea how much u just helped me with this comment appreciate your input

+em3rge1 No problem. I had to search google for pictures and found some that lined up with my engine. Im going to change mine this weekend to see if its going start up. I was warming up truck and after about 10-15 minutes it shut off. I replaced my plugs with new ones cause it wasn't getting any spark, along with a new coil pack, changed my rotor button with a used one. Finally got spark, spark seemed kind of weak but now truck acts like it wants to start up but it wont. So i kept checking out different videos until i came across one that made some real sense. Hope this works for the both of us.

+em3rge1 Made some real sense about the crank sensor position and how it will act up when it goes bad.

Nope. Plug and play. Thanks for watching!

@@2carpros Hi . I am needing to know if I'm understanding your answer here because I have asked several auto repair shops and Dealerships about having to do a " Relearn " or not after replacing the sensor and " they all said yes " , you have to do a relearn . So , before I do something that could possibly render my vehicle inoprable , I'm wanting to make sure . I have a " 2000 Chevy Silverado 1500 2WD with the 5.3 . I really appreciate the time and effort you put into not only doing the repair , but also the videoing of the job . Any help would be greatly appreciated .

@@jasond.606 Same here dealership and mechanic down the road both say a relearn is necessary

@@thesenewythandlessuck Thank you for that info . It sure will save me from having to call a tow truck to get it to the dealership to do a relearn if or when I decide to replace the sensor . Have a safe , healthy and happy new year .

@@jasond.606 You too👍

laura dawson should be up top some in the front I can't remember exactly it's been a few years since i have changed mine

Check you tube. I am sure there is a vid for that.

he does state most are 13 MM and he did say one was . a 15 , usally take a 13 mm 14 mm 15 mm and a 8 mm should do the trick on most starters today

Essentially the crankshaft makes the pistons run. You need one all the time. Thank you so much for watching!

Glad we could help! Please subscribe.

yes is will

Great additional info this truck started without a scanner, was the key on when you changed it? just wondering how the computer could tell?

The key was off and the negative battery cable was disconnected. I didn't think it would do that either but the truck ran so bad it wouldn't move after I was done. I even tried putting the old sensor back in. No luck.

and the truck runs okay after the relearn?

Yes.

good to know thanks for the info, we have never had this happen so there is a first for everything

Nothing you need to do. Thanks for watching!

@@2carpros hmm the dealerships and mechanics I spoke to say there is

Seems to be hit or miss. I have to for some but not others. Thanks for watching Christian!

5.3 I believe. But it is the same for all the LS based engines. Thanks for watching!

Nope. Thanks for watching!

You must perform a relearn process

You are so welcome! Thank you for watching!

And what engine do you have?

that is the starter sensor he is changing , there is nothing else there except that , prob not that same model and motor that you have

Could be a DOA sensor. I would return it and get an other new one. Thank you for watching!

Whenever replacing these crankshaft position sensor you must do a crankshaft variation relearn by using the GM scan tool those guys should know that

Aziz Saad This may be a little late for you, but I noticed no one answered you. I just had mine replaced. The vehicle would start & run normally while in "park", but would misfire and stall when I put it in drive and accelerate. It would be difficult to restart - I was thinking fuel pump - but once it started again it would idle and accelerate normally, as long as it was in park. I don't know if these symptoms are typical, but that is what my 97 chevy half ton did. Wish I had known. This is a pretty simple fix. I could have saved $350 in towing, rental, and repair costs. Hard to diagnose without a computer, although there are YT videos about that too.

chris lovessia Did your vehicle died randomly after you drove for a couple hours?

David Lopez The problem began immediately. From that point the engine would run while in park, but would backfire, miss badly, and then die when I tried to drive it. I had to have it towed to the shop. I wish I could have made it go for a couple hours lol.

+David Lopez - Our Car / Blazer died about 1-2 Hours in.... We were pulling all of our Hair out. Come to find out, it's the Coolant Sensor and it was $2.86 with free shipping. But for six Months, we couldn't figure it out :(((. Try this EASY TEST... All you need is a " Paper Clip " and you will find out right away !!! See this Video here....... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-q0v1kbw7iJI.html

Alex Galván Top of engine, in between firewall and intake manifold. Right next to oil pressure sending unit

Great comment! please subscribe.

Just an FYI. This sensor wasn't throwing a specific code. Just the p0300 code for multiple missfire. The fuel pressure what checked and is good, accelerator calibration was good, injector pulses are all good, I replaced the plugs and wires (as it was time), all sensors were reading good. I had this sensor replaced after having a local shop (GM shop) look at it, they advised this was teh issue. I advised that I had narrowed it down to this being the issue as well and wanted to confirm. This sensor being replaced also requires a GM Tech II crankshaft sensor relearn. They tried to relearn the factory sensor, it was still reading off. Sensor was replaced and relearn completed. No more issues! I Drove 3 hours without a single CEL blink. I even made sure to get the RPM's way up. *************** Please note: you DO need a GM tech II crankshaft sensor relearn after replacing this sensor.*********** (I knew this ahead of time)

the relearn is for 2004 and up. great info thanks for the tip.

I hope you're right because I'm going to replace it on my 2003 K 1500 suburban

It is a crankshaft sensor

What chevy V8 has a cam at the bottom of the engine?

The camshaft sensor is on top of the engine by the throttle position sensor.or atleast that's were mines located on my 99 silverado crank sensor is underneath the motor
