Local brought in a truck keeps throwing a cam position circuit code. They already changed the sensor and Dodge told them they needed an ECM. Looking at the scanner you can hold it at 1500rpms and the crank reading will stay steady but cam will go from 1500 to over 3000rpms intermitantly. Being that its jumping in rpm not dropping I too think it must be an ECM so I got another ecm programmed it and same thing.
So I am laying under the truck and start hearing a wierd noise from the middle of the truck, its the transfer case going in and out of 4wd (electric). Key is off and out and selector is to 2wd, turn key on it stops cycling, turn it off it starts cycling again.
So the transfer case thing I am thinking maby the TIPM is going nuts but not sure if the cam signal can be messed with by the TIPM but if it can be could be the whole issue.
Anyone else seen this?
