Cylinder 11 Injection Timing Performance - Over Advanced

Check these first

• Cylinder 11 injector firing early, so timing runs advanced
• A short or signal fault in the cylinder 11 injector circuit
• High fuel pressure at the cylinder 11 rail
• A sticking cylinder 11 injector
• A timing or cam signal fault skewing cylinder 11 injection

What to do next

1. Run an injector balance test on cylinder 11
2. Inspect the cylinder 11 injector connector and wiring
3. Check fuel pressure at the rail feeding cylinder 11
4. Check cam and crank timing signals
5. Replace the cylinder 11 injector if it sticks
6. Clear the code and retest
