Symptoms
MIL illuminated
Possible rough idle or reduced power
Possible causes
Valve timing
engine mechanical 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
