P03F7B Camshaft Position Actuator Position Sensor C Range/Performance (Bank 1)
Position sensor C reads in range but plausibility check fails — slow response or stuck reading. The camshaft position sensor identifies which cylinder is on the compression stroke — without it the ECM cannot run sequential injection or coil-on-plug ignition correctly.
