Description
The camshaft profile switching actuator for Bank 1, exhaust side, is mechanically stuck. The exhaust cam profile affects scavenging and emissions.
Symptoms
- Check Engine Light
- Poor emissions performance
- Reduced engine braking
- Slight power loss
- Failed emissions test
Common Causes
- Oil sludge in actuator passages
- Faulty solenoid
- Low oil pressure to actuator
- Worn actuator mechanism
- Carbon deposits
Diagnostic Steps
- Check oil condition and level
- Command exhaust cam profile switch
- Monitor cam profile position PID
- Test oil pressure at actuator
- Inspect actuator for carbon buildup
Repair Notes
Replace exhaust cam profile actuator. Perform engine oil flush if sludge is present.
