Symptom:
P0522-OIL PRESSURE SENSOR LOW
When Monitored and Set Condition:
P0522-OIL PRESSURE SENSOR LOW
When Monitored: With the ignition key on and battery voltage above 10.4 volts.
Set Condition: The oil pressure sensor voltage at PCM goes below 0.1 volts for 0.5 of a
second.
POSSIBLE CAUSES
GOOD TRIP EQUAL TO ZERO
OIL PRESSURE SENSOR INTERNAL FAILURE
(G6) OPS SIGNAL CIRCUIT OPEN
(G6) OPS SIGNAL CIRCUIT SHORTED TO VOLTAGE
PCM
TEST ACTION APPLICABILITY
1 NOTE: Diagnose and repair any other Sensor Voltage High DTCs before
performing this test.
Turn the ignition on, with the engine not running, for a minimum of 90 seconds.
With the DRBIIIt, read PCM DTCs and record the related Freeze Frame data.
Is the Good Trip counter displayed and equal to zero?
All
Yes → Go To 2
No → Refer to the INTERMITTENT CONDITION symptom in the
Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
2 Turn the ignition off.
Disconnect the Oil Pressure Sensor harness connector.
NOTE: When there is no oil pressure present, the Oil Pressure Sensor
contacts are normally closed.
NOTE: Engine must be off for a minimum of 90 seconds to allow for the oil
pressure to bleed down.
Measure the resistance between the Oil Pressure Sensor signal circuit terminal in
the Oil Pressure Sensor and ground.
Is the resistance above 5 ohms?
All
Yes → Replace the Oil Pressure Sensor.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 3
