i have an 04 dakota 4.7L magnum V8 that sat while i was out of town from TG to Xmas when i came home i got a P0344 code for intermittent Cam position sensor bank 1
so i replaced the cam position sensor and now it starts and runs a little worse and gives me P0340 code cam position sensor failure
so tested wiring and power, 12.45 V from battery, getting voltage to sensor, ground checked good, and signal wire is good.
i currently believe it to be the PCM and so before i go spend the money, that i dont really have to spend, to replace it i want to confirm that it is the PCM. could it be the crank sensor is bad and so the cam sensor isnt agreeing? could it be the replacement cam sensor, if so how would i test that? im just trying to eliminate all other possibilities before spending $200-$400 on the replacement

 

What engine?

 

4.7l magnum v8

 

Aftermarket sensor? Think I would try and swap that first.....

 

Moved to the correct section.

 

yes its a BWD sensor, its the only one carried in stock at my local auto parts stores, so i will have to order a mopar, couple more days without my truck :-( thanks for the tips tho

 

Just to add, it seems like most of the aftermarket sensors have problems. Yes the Mopar parts are more expensive but you figure the one you are replacing was 13-14 years old...

 

so today i finally got the sensor put on and.... mopar for the win, was only a couple bucks more but had to wait to have it shipped, but it got here and its on and it works, thank you all for the input

 

Yep, not a surprise. These trucks just do NOT like aftermarket sensors.....
