TEST ACTION APPLICABILITY
1 Turn the ignition off.
Disconnect the Fuel Pressure Sensor harness connector.
Disconnect the ECM harness connectors.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires. Repair as necessary.
Visually inspectthe related wiring harness connectors. Look forbroken, bent, pushed
out, or corroded terminals. Repair as necessary.
Measure the resistance of eachof thethree Fuel Pressure Sensor circuits between the
ECM harness connector and the Fuel Pressure Sensor harness connector.
Is the resistance below 10.0 ohms for each measurement?
All
Yes → Test Complete.
No → Repair open circuit(s) as necessary.
Perform ROAD TEST VERIFICATION - VER-2.
