P0524 - ENGINE OIL PRESSURE TOO LOW

The PCM (Powertrain Control Module) controls various sensors, switches, and other electrical components of the vehicle in order to make the vehicle operate as efficiently as possible. In the case of the Oil Pressure Sensor, it detects the amount of mechanical oil pressure in the engine. It then transmits this information in a voltage reading to the PCM. This value is then transmitted to a gauge located in the instrument cluster, which allows the driver to be aware of the oil pressure.

When the DTC P0524 OBDII code is set, it is because the PCM observed an excessive value from the Engine Oil Pressure Sensor. Note that such a condition is extremely dangerous to the engine, so you should stop and shut down the engine as soon as possible.

• Check Engine light comes on.
• The lamp illuminated indicating an oil pressure warning.
• The oil pressure gauge indicates low or no lev
• The engine exhibits abnormal noises.

The reasons for setting the P0524 OBD2 fault code are:

• Oil pressure or oil level may be excessively low.
• The engine oil provided may not be correct.
• The oil may be contaminated.
• The electrical circuit wires or connectors could be in poor condition.
• The Oil Pressure Sensor may be faulty.
• Faulty Crankshaft Position Sensor (POS).
• Faulty Camshaft Position Sensor (FASE).
• The intake valve control solenoid valve is faulty.
• Debris buildup on signal pickup side of the camshaft.
• Timing chain installation.
• Foreign matter trapped in the oil groove for intake valve timing control.

To troubleshoot P0524 OBDII diagnostic code errors you should consider the following:

• Consult the TSB (Technical Service Bulletins) that apply to your vehicle.
• Inspect the level and condition of the engine oil. It must have the proper level and determine that it has elements that contaminate it, you must perform the necessary maintenance.
• Inspect the Oil Pressure Sensor connectors and wiring. Repair or replace any of these that present inconsistency.
• Use a DVOM to check the resistance and other electrical values of the Oil Pressure Sensor. If it fails these checks, you should replace it.
• With a mechanical oil pressure gauge, check the oil pressure. If the pressure is excessively low, the problem is in the engine.
