CMP (Camshaft Position) Sensor and Its Circuit Inspection
- Confirm that terminal voltages and ground circuit continuity at CMP sensor connector terminals is in good condition. See DTC P0340: CAMSHAFT POSITION SENSOR CIRCUIT
.
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. See INSPECTION OF ECM AND ITS CIRCUITS .
- Check that CMP sensor waveform as specified referring to "REFERENCE WAVEFORM NO.19 AND NO. 20" under INSPECTION OF ECM AND ITS CIRCUITS
.
If waveform is out of specification, replace CMP sensor.
If waveform as specified, CMP sensor is in good condition.
