P03E6A Camshaft Position Actuator Position Sensor C Range/Performance Bank 1

P03E6 indicates that the engine control module (ECM) has detected an out-of-range or performance problem with the camshaft position actuator position sensor 'C' on bank 1. The sensor reports the actual position of the camshaft phaser, and the ECM compares this signal against the commanded position to verify the variable valve timing system is responding correctly.
