Exhaust Camshaft Position Timing Over-Retarded (Bank 1)

What This Means

The exhaust camshaft on bank 1 is more retarded than commanded. The exhaust valves are closing later than optimal, which can increase emissions and reduce engine efficiency.

Common Symptoms

• Reduced engine power
• Rough idle
• Increased emissions
• Check engine light on

Common Causes

• Low oil pressure
• Dirty engine oil
• Faulty VVT solenoid
• Worn timing components
• Clogged oil passages
