Camshaft Position Sensor: Testing and Inspection
CMP (Camshaft Position) Sensor and Its Circuit Inspection
1. Confirm that terminal voltages and ground circuit continuity at CMP sensor connector terminals is in good condition.
If terminal voltages and ground circuit continuity are specified value, go to next step. If terminal voltages or ground circuit continuity is out of
specification, check and/or repair CMP sensor circuit.
If CMP sensor circuits are in good condition, check ECM.
2. Check that CMP sensor waveform as specified.
If waveform is out of specification, replace CMP sensor.
If waveform as specified, CMP sensor is in good condition.
