P0523-OIL PRESSURE CIRCUIT HIGH (CONTINUED) 3. (G6) OIL PRESSURE SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE Turn the ignition off. Disconnect the PCM harness connectors. Ignition on, engine not running. Using a 12-volt test light connected to ground, probe the (G6) Oil Pressure Signal circuit. Is the test light brightly illuminated? Yes >> Repair the short to voltage in the (G6) Oil Pressure Signal circuit. Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) No >> Go To 4 4. (G6) OIL PRESSURE SIGNAL CIRCUIT OPEN Turn the ignition off. Measure the resistance of the (G6) Oil Pressure Signal circuit from the Oil Pressure Sensor harness connector to Is the resistance below 5.0 ohms? Yes >> Go To 5 No >> Repair the open in the (G6) Oil Pressure Signal circuit. Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) Per- 5. (K900) SENSOR GROUND CIRCUIT OPEN Measure the resistance of the (K900) Sensor ground circuit from the Oil Pressure Sensor harness connector to the Is the resistance below 5.0 ohms? Yes >> Go To 6 No >> Repair the open in the (K900) Sensor ground circuit. Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) 6. PCM NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal If there are no possible causes remaining, view repair. Repair Replace and program the Powertrain Control Module per Service Information. Perform POWERTRAIN VERIFICATION TEST.
