Cam and crank position sensor codes thrown after clutch and CSC failure
Last thursday the clutch and CSC in my 2014 touring went out. The clutch was completely destroyed, and my OBDII read three new codes, a P0340, P0345 and P0335. The 340 and 345 codes refer to both cam position sensors and the P0335 refers to the single crank position sensor.
Has anyone had their Z throw position sensor codes after a CSC and/or clutch failure? I'd like to run tests on the crank sensor, but I can't find diagnostic measurements like resistance in any service manual. Any help or insight would be appreciated, TIA. |

First thing that pops into my head is a wiring/harness/connector problem.

Cant post the pics. Check Crankshaft sensor for chipping. You ring gear may have also chipped. Sounds like a catastrophic failure. The FSM shows many variables. Too many to list for you. Sorry. Get a hold of the FSM and go to the chapter i quoted. As SouthArk has suggested, start with easy stuff. |

Did you visually inspect the crank sensor for damage since the cluth failed? I know it's a pain to get to but pull it for a visual inspection.
The cam shaft codes in the situation are most likely correlation codes. The pcm has to have sync between the two for fuel and spark timing. I would say it's safe to assume you probably couldn't start the car when the cluth went boom not knowing you had these codes?

I noticed that in the bellhousing, there were friction/score marks from the clutch when it blew up, and some of them lead to the where the crank sensor sits. I checked it for physical signs of damage but it was fine. Hopefully it stays that way.
I have since replaced the clutch and flywheel with JWT's lightweight flywheel and heavy duty clutch and I put the transmission back in. The code has not reappeared. Thank you all for your input! |
