On-Vehicle Inspection

1. Warm up engine and run at idle.
2. Listen for "click" at each injector with a screwdriver or stethoscope.
3. If no sound is heard while cranking, check resistance at each injector. It should be 12 - 16 ohms.
4. If injector resistance is okay, check wiring to injectors and voltages at PCME terminals:
^ California B6: 2A, 2U, 2V, 2Y, and 2Z
^ MTX except Calif. B6: 2A, 2U, and 2V
^ ATX except Calif. B6: 3A, 3U, and 3V

5. For further PCME troubleshooting information, refer to Computers and Control Systems.
