P0524 OIL PRESSURE TOO LOW

When Monitored and Set Condition:

When Monitored: While the engine is running.
Set Condition: The oil pressure detected by the ECM is less than a calibrated value.

POSSIBLE CAUSES

• LOW OIL LEVEL
• (G60) SIGNAL CIRCUIT SHORT TO GROUND
• OIL PRESSURE SWITCH
• INTERNAL ENGINE DAMAGE

DIAGNOSTIC PROCEDURE

1. Check the engine oil level. Is the engine oil in the safe operating range?
   Yes --> Go To 2
   No --> Repair any condition that may cause the oil level to be above or below the safe operating range.
2. With the DRBIII®, erase DTCs. Turn the ignition off. Disconnect the oil pressure switch harness connector. Turn the ignition on for 1 minute. Did DTC P0521 set?
   Yes --> Go To 3
   No --> Repair the (G60) signal circuit shorted to ground.
3. Measure the engine oil pressure with a mechanical gauge. Is the oil pressure within the acceptable operating range?
   Yes --> Replace the oil pressure switch.
   No --> Repair internal engine damage.
