P0522-OIL PRESSURE CIRCUIT LOW —
TEST
4 Turn the ignition off.
Disconnect the PCM harness connectors.
Measure the resistance between (G60) Oil Pressure Signal circuit and ground at the
Sensor connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (G60) Oil Pressure Signal
No
5 Measure the resistance between the (G60) Oil Pressure Signal circuit and the (K900)
Sensor ground circuit at the Sensor connector.
Is the resistance below 5.0 ohms?
Yes → Repair the short between the (K900) Sensor ground and the (G60)
No
6 Turn the ignition off.
Disconnect the PCM harness connectors.
Measure the resistance of the (K7) 5-volt Supply circuit from the Sensor harness
connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 7
No
7 Measure the resistance between ground and the (K7) 5-volt Supply circuit in the Oil
Pressure Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K7) 5-volt Supply circuit.
No
8 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.
