location of cam sensor
im getting a P0344 (cam sensor circuit intermittent), i need to know where the sensor is so i can do some more tests to determine if the sensor is bad
anyone know where its at (engine is an '03 4.7ltr), i think its the sensor above the oil filter, but im unsure and wanted more input on it

RE: location of cam sensor
OF:
Cam sensors are usually attached to the end of the head. I have not specifically located the one on my 01 4.7, but if you see a sensor mounted to the front of either head that is probably it. I would hope they would not have mounted it to the rear which would be a nightmare.
What symptoms are you having?? If it is a starting issue, the CS can surely cause that.

Yes the 4.7 is an SOHC motor.
As a semi educated guess, I think the cam sensor is only used upon engine start up so the computer will know where the cam is in relation to the crank for timing. I don't think that info is needed anymore once the engine is running.
If anyone can confirm or deny this theory, please speak up!!!!!!!!!!!!!!!!!!!!!!

RE: location of cam sensor
if it was only used on start-up then why am i experiencing drivibility issues during normal driving? like stalling, loss of power from ignition cutting out, etc
i have reset my computer, unplugged all 4 connectors checked pins 34 and 35 (cam and crank respectivly) of connector 2 (grey/white), both contacts appear to be at correct depth in plug, i believe the issue lies in the plug where the wire meets the metal contact piece, unsure of how to test this
need to know location of cam and crank sensors for further testing with DMM and O-Scope
will be datalogging code set on monday to check other parameters occuring when code is set

RE: location of cam sensor
did some more digging
CMP is located front of engine passenger cylinder head, below valve cover
CKP is located in block next to starter (starter does not need to be removed to service sensor)
there is a TSB out for loss or interrmittent loss of CMP signal (TSB #082200 dated in 2000)
https://dodgeforum.com/recalls-and-t...082200/TSB.htm
CKP failure is also known to throw P0344 code
upon inspection of my own motor, wire harness for CMP appears to have been moved (factory wire retainer that slides onto valve cover bolt, was not on said bolt) leading me to believe this is a prior issue
also: fault (loss of signal) must occur 20 times before MIL will come on
also: CMP is monitored at all times, to keep motor in time, since timing is always changing during accel and decel, PCM must compare CKP and CMP to determine proper timing

RE: location of cam sensor
took out CMP, no visible damage from contact with reluctor, pulling CKP next to inspect
believe issue may be related to connections not the sensors themselves
found another TSB relating to erronious codes being set, for total loss of CKP or CMP signal, believe my issue may be related, correction for that TSB is total PCM reflash....doing more research into this TSB will post more info later
