Im throwing codes 335 and 336, which are some crankshaft sensore codes. I have replaced the sensor but am still throwing the codes. Any ideas as to why, and also if this would be causing the miss im getting after the h/c install. thanks

 

The 335 is for a circuit problem. Usually do to a connection/wiring problem. The 336 is performance. Therefore if you have a cut wire, you should have both codes. A problem with the CKP will not cause a misfire. It's only there for reporting purposes.

First, any time you have a sensor problem, check the wiring. In the case of a 3 wire sensor like the CKP, check for the presense of 12 volts and ground and ohm the signal wire if you can't actually confirm the signal, from source to destination.

In this case, the pink/black wire is ground and the pink wire is 12 volts. Then ohm the yellow wire back to the PCM on the red connector first pin.

The interesting part about your problem is the 12 volts that powers the CKP from fuse 11 underhood, is also the same source that powers the ignition system. So it would be a good assumption that perhaps this 12 volts is dropping out occasionally causing your miss and the CKP problem.

Start by checking the connection at the fuse and then connector C100. The black 10 pin connector near the PCM. It's the pink wire that is NOT on the end pin. I would put a meter in the connector for the CKP and wiggle every part of the wiring from the fuse to the splice where the wires split off to the different devices. I suspect your problem lies somewhere from the fuse through C100 upto the splice.
