SYMPTOM
P0340 - NO CAM SIGNAL AT PCM

WHEN MONITORED
Engine cranking/running.

SET CONDITION

- CMP signal circuit shorted to 8 volt supply circuit
- CMP signal circuit shorted to voltage
- Tone wheel/pulse ring damaged
- Sensor ground circuit open
- Wiring harness intermittent problem
- Stray signal from the Crankshaft Position Sensor
- Irregular lab scope pattern of CMP signal
- CMP signal circuit open
- CMP signal circuit shorted to ground
- CMP signal circuit shorted to sensor ground circuit
- 8 volt supply circuit open
- 8 volt supply circuit shorted to ground
- 8 volt supply circuit shorted to sensor ground circuit
- Camshaft Position Sensor
- Powertrain Control Module (8 volt supply)
- Powertrain Control Module (CMP signal circuit)
- Powertrain Control Module (sensor ground circuit)
