Code P2616 GMC Description

The P2616 GMC code indicates a problem with the camshaft position signal output circuit being too high. This means that the signal being sent from the camshaft position sensor to the engine control module (ECM) is registering as higher than the expected voltage range. The camshaft position sensor is a crucial component that helps the ECM determine the position of the camshaft in relation to the crankshaft. This information is essential for the ECM to properly control fuel injection timing and ignition timing.
