Any time a customer works on their own vehicle before bringing it to you can cause you to try and figure out if the work they did caused the problem. SureTrack community member HcTruckRepair had a Dodge Grand Caravan in their shop where the customer replaced the rocker arms and then ended up with a P0344 cam sensor code. They posed the question to the community, and with the help of fellow community member RVAAuto and others, they were able to resolve the issue quickly.
The following Community Fix summarizes the interaction between members of the community that led to the solution.
2017 Dodge Grand Caravan SE 3.6L
P0344 After Rocker Arm Replacement, replaced cam sensor.
Customer states that check engine light is on.
Diagnostic Steps Performed/Parts Replaced
Customer brought in vehicle after changing their own rocker arms. Code P0344-Camshaft Position Sensor Intermittent – Bank 1 Sensor 1 present. Claims they released bank 2 timing chain with the hook tool but they did not. Somehow they still changed the rockers. I removed valve covers to check, and all rocker arms had been changed, new cam sensor on Bank 1. I did not see damage to bank 1 cam wheels. What could be causing this issue? Could they have bent the cam getting the rocker arms out by prying up on the cam? Replace the cam sensor but still same issue. Where to look from here?
Best Answer from Community Member RVAAuto
Scope the cam signal and compare to the good bank. They might have demagnetized a section of the trigger (tone) wheel.
They used a magnet to remove the rockers, wiped out a spot on the cam sensor tone wheel causing bad signal.
Replaced Bank 1 cam sensor tone wheel and issue is resolved.
