ACDelco GM Original Equipment 213-354 Engine Crankshaft Position Sensor

Good

Worked for my 2001 Silverado 5.8L V8. I had intermittent stalls and rough idle for over a year (no codes on PCM). It got bad enough to stall after it got warmed up, every time. Would not start again until it cooled off and it ran perfect till warm again. I was ready to junk it. Finally got the code P0336 and this was the problem. It does not always set a code at first. Look on the forums and this is a very common issue for these engines. Now I know what to look for next ttme.OEM part for half the price of dealer part. Took about 1 hour to install. Drop the starter (leave the wires connected) and move it under exhaust manifold. The sensor is behind the starter. Remove the connector and one bolt holds it. Safety reminder: Don't forget to unhook the battery and use jack stands when you jack it up. 2 starter bolts are 13mm and sensor bolt is 10mm. Replace this sensor before you replace fuel pump, injectors or MAF etc. This is an easy repair and cheap.

ok

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.

I have been chasing a code P0300 for the longest time on my 1999 GMC Sierra 1500. This code is very generic for Engine Random misfire. This code points to about everything on the engine and fuel system. I did some repairs and put some fuel system cleaner. Finally in the last month or so I got a different code that directed me to the crankshaft position sensor. I ordered it, it was delivered as expected and I installed it this weekend. It took me about 1 1/2 hour to do this. Not only did it clear the issue with the Crankshaft position code it also clear the P0300 code. The engine is running as smooth as ever even on cold start.One note, the sensor is located behind the starter when looking from below the truck. It is a bit tricky to get to and pull out since you have to drop the starter. it is a bit of tight squeeze under there.

When my truck quit it seemed to be running out of gas. So changed the filter to no avail. Same with the fuel pump. Runs for a while then quits and sputters just like running out of gas. A GM mechanic suggested I change the crankshaft position sensor. Problem solved. This sensor will not cause codes and when it warms up it just sputters to a halt. Much cheaper than the fuel pump too I might add. If your GM pick up or van has these symptoms. Try changing the crank sensor above the starter on the 6.0 liter engine first. This Delco product is exactly the same as the dealer product. The dealer wants over twice as much for the same sensor. The part numbers are different but it's the same item.
