Cam Sensor Codes and others

[DeadSpool]

I finally took the car out for the first drive of the year since the snow finally melted. I just drove 5miles or so then went home. Everything ran perfectly. I shut the car off in my driveway then went to restart it and it struggled to fire and it flashed “system charging issues” in the cluster then fired, I got 8 cam position sensor codes:


P0344 - Camshaft Position Sensor A circuit intermittent
P0345 - Camshaft Position Sensor A circuit
P0349 - Camshaft Position Sensor A circuit intermittent
P0365- Camshaft Position Sensor B circuit
P0369- Camshaft Position Sensor B circuit intermittent
P0390- Camshaft Position Sensor B circuit
P0394- Camshaft Position Sensor B circuit Intermittent

I cleared the codes then it fired perfectly, drove it into the garage, pulled the battery terminals to do a reset and inspect the terminals which were all good, alternator & starter cables all looked good aswell.

I started it up and it ran perfectly, cycled it off and on 4 times to see and all good. Took it for a 10mile test drive and it was perfect, took it home and shut it off, went to start it right after and the same thing with the starting issues. system charging issues popped up while cranking again and cel came back on. This time with only 2 cam sensor codes and other ones:

P0345- Cam position sensor A circuit “a”
P2156- O2 sensor signal biased/stuck rich “a”
P0345- Cam position sensor A circuit “p”
P02196- O2 sensor signal biased/stuck rich “p”

I spent a good hour searching old posts and seen so many regarding a sensor being bad, harness, alternator, etc. None of these seemed to have all the symptoms I’ve described and the exact issues.

Help and insight is needed!

Check to make sure a rodent didn't chew through any harnesses... very common issue with rodents eating vehicle wiring harnesses when stored for a long period of time.

Also check all grounds under the hood to make sure those are secure.

Go to the CAM sensor and make sure that the connector to it is pushed on all the way and is not loose.

Did you hit on these threads regarding the CAM sensor?

Hi @DeadSpool . What happened after that. Did you find any solution for it. I have the same issue now on my 2016 mustang gt

I changed out the o2 and codes never came back.

Ohh i ll try doing that. The weird thing is my car is running fine but it just revs up and down at idle and stalls sometimes but mostly its the rough idling. I changed the cam shaft positioning sensors yesterday and the codes started coming today. Idk if it ll be alright in a while. I need to change my VCT solenoids and O2 sensor. Thanks for the info.
