Component Testing
WARNING: This page is about a different variant/trim than selected.
- Ignition OFF, disconnect the harness connector at the G18 High Pressure Fuel Pump.
- Test for 0.3-0.7 Ω at 20°C (68°F) between the low control circuit terminal 1 and the high control circuit terminal 2.
- If not between 0.3-0.7 Ω
Replace the G18 High Pressure Fuel Pump.
- If between 0.3-0.7 Ω
- If not between 0.3-0.7 Ω
- Test for infinite resistance between each terminal and the G18 High Pressure Fuel Pump housing.
- If less than infinite resistance
Replace the G18 High Pressure Fuel Pump.
- If infinite resistance
- If less than infinite resistance
- All OK
NOTE:
The DMM and test leads must be calibrated to 0 Ω in order to prevent misdiagnosis.
