Fuel Injector Group G Supply Voltage Circuit High

Where it lives

For P217C, the injector sits on the circuit this code reports. The description of P217C reports a fault at the injector.

Check these first

• A short to voltage in the group G supply voltage circuit
• High resistance in the group G supply voltage circuit
• A failed group G supply relay or fuse
• A failed group G fuel injector
• Low fuel pressure or a weak fuel pressure regulator

What to do next

1. Read the group G injector supply voltage on a scan tool
2. Test the group G supply circuit for a short to voltage
3. Check the group G supply relay and fuse
4. Measure resistance in the group G supply circuit
5. Replace the group G injector or its relay if faulty
6. Clear the code and retest
