Crankshaft sensor code? P0337 Hey guys and gals. I just finished replacing my Knock sensors, knock sensor harness and Oil Pressure sending unit.
Before this I would periodically get a SES light for a knock sensor ground low voltage reading. But I would only get the SES light about once a week and it would go away after a few times of shutting it off and starting back up.
But now after replacing these parts my SES light is on constantly. I went to AutoZone to get the codes read. I am throwing a P0337, the tech there told me it is a Crankshaft sensor code. What would cause a crankshaft sensor code to be thrown? And what should I do about it? I hate having the SES light on constanly, I don't want to be throwing another code and not know about it.

I've searched in the search box above and on google and haven't found anything except just an explanation of what the code is, which I already know. I need to know what could be causing this code and what I should check to solve it!

I had the same thing, but my car would not start (or it would start, run for ~5 minutes, and then cut off while moving) until I replaced the crank position sensor behind the starter.
The hardest part of the whole job was getting it up on the jack/jackstands, and the CPS is not very much coin.
It could be a ground wire, or the CPS wire into the ECM, but you will go crazy looking for that, so I would just try replacing the CPS itself first.

Ok, so it's right behind the starter? Should I get the part from GM or is it the same thing at autozone/oreillys?
My car starts and runs fine, but it feels slightly sluggish and not as responsive on the throttle but it's just a fraction. Could just be my imagination b/c the SES light is on.

Check out all the connectors and wiring, make sure nothing is burned or loose. If you change the crank position sensor, you might need to have a CASE relearn performed on it as well. The dealer or someone with scanning software can do it for you.
