SYMPTOM
P0340-NO CAM SIGNAL AT PCM

WHEN MONITORED
Engine cranking/running. Battery voltage greater than 10 volts.

SET CONDITION
At least 5 seconds or 2.5 engine revolutions have elapsed with crankshaft position sensor signals present but no camshaft position sensor signal.

POSSIBLE CAUSES
- Intermittent crankshaft position sensor signal
- Intermittent camshaft position sensor signal
- Intermittent wiring
- Intermittent condition
- (K7) 8-volt supply circuit shorted to ground
- (K7) 8-volt supply circuit open
- (K7) 8-volt supply circuit shorted to voltage
- (K44) CMP sensor signal circuit shorted ground
- (K44) CMP sensor signal circuit open
- (K44) CMP sensor signal circuit shorted to voltage
- (K44) CMP sensor signal shorted to (K7) 8-volt supply circuit
- (K4) sensor ground circuit open
- PCM - (K7) 8-volt supply
- PCM - (K44) CMP sensor signal
- Camshaft position sensor
