A9: Check Injector Ground

NOTE: This test is appropriate for a ground fault on 1A, 2B, 3B, 4A, therefore codes P0201, P0206, P0207 & P0204 will be present.





Measure the resistance between EM015/011 and ground EM1AR.

Is the resistance < 0.5 ohms?

Yes
Go to A10 A10: Check For Short to 1B, 2A, 3A, 4B GND

No
Repair the connector EM015/011 for bent/damaged pin, harness or ground EM1AR and test the system for normal operation
