- Changing the cam position sensor in a 2008 GMC Sierra 5.3 4WD.
Applies to 2007.5 - 2014 with NON VVT.
This is an LH6, YMMV.
2 wheel drives would/could be similar (?).

LUBE SENSOR FIRST! it has a very tight fitting O-ring hot used motor oil dribbled ontop of the sensor with a narrow funnel, only needs a tiny bit but feel free to dump an oil filters worth if it makes you feel better, i just used a little bit. twist more than pull to get it out, i used a long bent snot needle nose pliers, others have recommended a spark plug wrench, i used what i had on hand. put the new one in by hand after dipping it in hot used motor oil and quicker twisting action, but less twist so as not to bind up the seal and roll it/twist it in the holes sleeve and used alot more push force than twist. went in so easy i wasn't sure i had it seated fully as there is about a washers gap from the sensors body limit due to the retainer bolt flange mount.
watched this video to figure out a way to get the computer to accept the new sensor with out going to a dealer for reprogramming calibration. some one said drive it for 40 miles the computer will self relearn. i've only gone about 30 miles so far so? this video was no help in that department.
Thank you very much! Finally a video on this exact truck and engine with an easy removal and install, very good work.
You're quite welcome, glad it helped you out. I did it once before from the top (side of the road type fix!) and it was a horrible job (you just can't see anything, and human hands are NOT meant to contort like that!) - so when I had the time to do it on this one the right way, I had to film it.
Great
I used a drywall screw and a hammer to take it out came right out first try after it broke
any recommendations on how to remove the sensor if it won’t come out easily?
I'll assume you've gained access to it, and got the bolt out - almost for sure you've got "dingy yellow build up" on the portion that extends through the cover. It makes it larger than the hole. So, you can TRY gently pulling on it while turning it around and around. Sometimes that will grind up the scum ring until it lets go. You can also grab some carb cleaner, and blast it down the gap, then pull and turn it a bunch, blast some more... repeat ad nauseam. Carb cleaner is mostly acetone and will dissolve nearly everything. Including your hands! So wear good (not latex) gloves. And don't breath the shit.
When the top breaks off, you'll have to drill a hole in the remaining part of the sensor and thread in a 5" lag bolt to use as leverage to pull out. Not for the faint of heart. Otherwise, you'll be pulling the timing cover.
So is this the same for a 2014 gmc Yukon 5.3? This is the camshaft position sensor?
IF you have VVT, it'll look different. Otherwise - should be the same.
@@DrFiero what is vvt?
@@jaredvera7079 - Variable Valve Timing.
If your timing cover looks like mine (not as shiny doesn't count!) then you DON'T have VVT.
VVT covers have a big hump. Very noticeably different.
I have a 2011 Silverado z71 LTZ 5.3 and my setup is nothing like this. I have a metal shield surrounding the wiring harness and it will not come out unless that pulley comes off.
There's a metal shield over this one as well - and I've had it in/out a few times with the crank pulley in place. Just for funsies I looked up the harness specifying your year etc - exactly the same part number!
Yup what this guy is showing is not like ours I just did a 2012 gmc 5.3 his was easy the ones we have have another wire harness going over the timing Chain cover up too another sensor and yes same part BUT DIFFERENT HARNESS THEIRS a 3rd bolt right under the main pulley I used a swivel head wratchet wrench and it worked for me thank God but the sensor ballooned in the block took me 3 dam hours to get that thing out and a ton of cuss words this always seems to help me 😂😂.. but yeah same part Different harness
@@eddietrujillo224 - do you have VVT on yours? If so it’s simply not the same engine and would then be a different job.
My 2011 LT 5.3 looks just like this, same thing.
Yeah, they don't come out that easy.... Anyone reading this, and thinking of changing their own, should be ready to deal with an extraction process that involves drilling the senor and using a 4-5" lag bolt screwed into the hole to extract. If that doesn't work, you're pulling the timing cover. So be prepared for a headache. Not a task for the average DIY'er.
Yea not even close on a 14 Silverado!
