Injection Pump Timing Offset

Where it lives

For P2672, start at the pump the description names.

Check these first

• Worn timing components letting the injection pump timing drift
• A failed crankshaft or camshaft position sensor skewing the timing reference
• Incorrect injection pump timing after a pump or belt service
• Air in the fuel skewing the injection event

What to do next

1. Read the injection pump timing offset on a scan tool
2. Compare crankshaft and camshaft position signals
3. Check the fuel system for air or low supply pressure
4. Verify the injection pump is timed to the marked position
5. Relearn the injection pump timing if the reference signals test good
6. Clear the code and retest
