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 inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals. Repair as necessary.
Measure the resistance of each of the three Fuel Pressure Sensor circuits between the
