After getting a P0335 engine code and the car stalling at random times, I decided to replace the sensor. A buddy and I had time last night to work on it thinking it would be a quick job, maybe not taking more than an hour. Everything was going fairly smooth, until we tried taking the sensor out. It would not come out and when it finally did it left behind the black plastic shroud that encases the end of the sensor still stuck in the hole. My buddy has been trying everything he knows to get it out and for some reason it seems to be fused inside the hole. He has been picking at it and getting very small pieces out, this is very frustrating. Wondering if anyone has any ideas or has seen or heard of this ever happening.

Heed how to reposition it in this thread (with regular step-by-step instructions). Make sure you pay attention to the new bolt size and head type to use =

The link you provided was for the knock sensor. I am having issues with a broken and stuck crankshaft position sensor. The one you can get access to by taking off the front passenger wheel and the lower wheel well liner. My knock sensor has broken off and we cannot get the broken portion out of the block. Looking for any ideas on that. Thanks.

 

I can't imagine that sensor being stuck in there. It's just a bolt and slide the sensor out. There is a possibility that there is internal damage (flywheel) that has somehow buggered up the sensor so badly that it won't slide out. Did you also have another code thrown on some cars it's a p1336 for flywheel chipping (not sure if it's the same on X type). That indicates internal damage where the knock sensor is detecting, but it's erratic due to damage internally (usually the teeth that can be seen through the hole after sensor removed).

 

Had to take her to the shop to have the sensor removed fully. Mechanic with 40 years experience took two hours to get the remainder of the sensor out. All that was left in the hole was the plastic outer ring of the sensor after it broke. All of the internal parts of the sensor came out. The mechanic ended up having to liberally spray the area with some type of industrial penetrant, then he heated up the plastic piece, then he stuck a punch inside and cut through the plastic piece. From there he pulled and yanked at it until it eventually popped out. He replaced with the new sensor, cleared the codes and did a test drive. Everything appears to run fine now.

Googling "broken crankshaft sensor in engine" returns numerous results about others who have had the same issue. Definite learning lesson that should have been an easy and relatively cheap DIY, turned into more expensive than expected.
