ACDelco GM Original Equipment 213-354 Engine Crankshaft Position Sensor

Good

ok

I installed a new engine in my Silverado and purchased aftermarket sensors for cheap. What a mistake!! My PCU/ECM couldn't recognize two of the sensors (Crank & Camshaft position sensors) and I had to spend many hours of troubleshooting and knuckle busting replacing them with Genuine GM/ACDelco. They worked perfectly and are priced great on Amazon.

I've had the occasional PO300 code (random misfire) on my Silverado, but just thought maybe it was bad gas. I would just throw some fuel injector cleaner in the gas tank, and it would be good for awhile. Last week, the truck threw a PO336 code (crank position sensor) So I ordered a new one. Don't bother with any other brand, ACDelco is a trusted GM factory parts brand made by GM (they own ACDelco).Make sure to disconnect the negative battery cable before installing the new sensor. You'll have to remove the starter --> (2) 13mm bolts and a 10mm bolt holding the plastic splash shield ( I left the cables attached ) and move it off to one side. It is a little difficult, but it can be done. The crank position sensor is above the starter. Unplug the electrical connector to the crank sensor and remove any loose debris like flaking rust away from the block. There is a 10mm bolt holding the sensor to the block. I used a long extension and removed the bolt from the right wheel well. I then used a long shaft flat blade screw driver and gently pried on the old sensor until it popped out of the bore in the block. Oil the O-ring on the new sensor and insert into the bore. Plug in the connector, put the starter back into the housing and tighten up the 2 bolts. Reconnect the negative battery cable and you should be good to go. My truck fired right up and ran very, very smoothly. Some people say that you should get a relearn procedure done with a scan tool, but I didn't and I don't have any codes. Everything is good to go.Despite what the Amazon listing says about this crank position sensor NOT fitting my truck, it DOES INDEED fit my truck: 2003 Silverado LS, 4.8Litre V8. I have verified this with GM Parts Direct, Rockauto, Summit Racing, and countless other sources. The new sensor is in EVERY way IDENTICAL to the old one.My truck idles so smoothly now and accelerates like a rocket😁👍Edit: August 29 2020- I had a CKP variation relearn done at my local GM dealer as I had read that not getting a relearn done might make the engine over-rev, which is NOT good.

Installed like normal. Verified packaging and part number for any signs of being a counterfeit, none found. Installed and vehicle fired right up after being a crank, no start. Performed crankshaft position relearn, no issues to date.

Perfect fit, working fine
