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
