Cylinder 3 Alternative Fuel Injector Control Circuit High

Where it lives

For P22E3, the circuit described runs through the injector. The description of P22E3 puts it on cylinder 3.

Check these first

• A cylinder 3 alternative fuel injector control wire shorted to voltage
• An open injector control circuit
• A failed cylinder 3 alternative fuel injector
• High resistance in the injector circuit

What to do next

1. Command the cylinder 3 alternative fuel injector on a scan tool
2. Test the injector control wire for a short to voltage
3. Check the injector control circuit for an open
4. Measure cylinder 3 alternative fuel injector resistance
5. Replace the cylinder 3 alternative fuel injector if the circuit tests good
6. Clear the code and retest
