P03E7A Camshaft Position Actuator Position Sensor C Circuit Low Bank 1

P03E7 indicates that the powertrain control module has detected an abnormally low voltage signal on the camshaft position actuator position sensor C circuit for bank 1. This sensor reports the actual position of the camshaft phaser, and a low signal means the PCM cannot trust the feedback, so it may disable variable valve timing and set the warning light.
