Injection Pump Timing Offset
The high-pressure injection pump timing is offset from the expected reference. On distributor pumps with a timing solenoid, the actuator does not match the commanded position.
Affected components
- Injection pump
- Timing actuator
Common causes
- High likelihood: Worn timing actuator piston or seal
- Medium likelihood: Stretched pump drive chain or belt
Diagnostic notes
- The malfunction indicator lamp may illuminate
