Data confidence65%
The control module detected a fault associated with the B Camshaft Position Actuator Temperature Sensor Circuit Bank 2 circuit or function; the stored code identifies the affected component rather than a single failure mode.
Symptoms
MIL illuminated
Possible rough idle or reduced power
Possible causes
Low oil level/pressure or degraded oil
VVT solenoid (oil control valve) fault
Timing chain stretch or incorrect timing
Camshaft adjuster fault
Wiring fault
Recommended checks
Check oil level and condition first
Read specified vs actual cam timing with live data
Actuate the VVT solenoid and verify response
Check timing marks/chain condition if deviation persists
Powertrain: engine, transmission and driveline systems.
