DTC
Description
Possible Cause
Action
Camshaft inlet sensor, short
circuit to ground, short
circuit to power, open circuit,
high resistance
Camshaft inlet sensor
air-gap to target rotor
greater than specification
Excessive run out on target
rotor
Loose variable valve timing
actuator chain drive or
tensioners
Damaged, worn timing chain
installation
Refer to electrical circuit diagrams and check
the camshaft inlet sensor circuit for short
circuit to ground, short circuit to power, open
circuit, high resistance
Refer to the relevant sections of the
workshop manual and check the camshaft
inlet sensor for correct air-gap to target rotor
spacing, check target run out is to
specification, check variable valve timing
actuator chain drive or tensioners are
operating to specification
