DTC P0340
Camshaft sensor fault/Valve timing error Drive cycle A:Signal implausible.

Possible causes by suggested order of priority:
^ Camshaft sensor fault.
^ Open circuit - C636/20 (SU) to C176/2 (SU).
^ Open circuit - C636/17 (B) to C176/1 (B).
^ Voltage incorrect C176/3 (NK) to C176/1 (B).
^ Connector C176.
^ Crankshaft sensor problem.

Camshaft Sensor Fault.
CHECK THE FOLLOWING:
^ Inspect camshaft sensor for evidence of damage.
^ Check camshaft sensor by substitution with a known good unit.
POSSIBLE FAULTS
^ Faulty camshaft sensor.

Open Circuit - C636/20 (SU) to C176/2 (SU).
OPEN_CIRCUIT
^ Check resistance > 1M Ohm

Open Circuit - C636/17 (B) to C176/1 (B).
OPEN_CIRCUIT
^ Check resistance > 1M Ohm

Voltage Incorrect C176/3 (NK) to C176/1 (B).
CHECK THE FOLLOWING:
