P0524 OBD-II Trouble Code: Engine Oil Pressure Too Low

P0524 code definition

When the PCM of a vehicle stores this code, it’s because its oil sensor detects that the amount of engine oil pressure is too low.

What the P0524 code means

The vehicle’s PCM is responsible for monitoring overall performance, which it is able to do thanks to a number of different sensors, controls and other types of electronics. One of these is the oil pressure sensor. It tracks how much oil pressure is present in the engine and continuously sends that data back to the PMC in the form of a voltage reading. In some vehicles, the amount is also passed onto the driver. In others, they simply get a warning light when it is becoming too low.

When the oil pressure becomes too low, this code is triggered. If the warning light is ignored, oil levels could get low enough that the engine is permanently damaged.

Along with code P0524 being stored, the check engine light should come on too. Other codes associated with this one include P0523, P0522, P0521 and P0520.

What causes the P0524 code?

Generally, this code is stored because you don’t have enough oil in your vehicle for the near future.

There could be other reasons, though:

• Incorrect oil viscosity
• The oil is contaminated (could be from coolant, fuel, etc.)
• The oil pressure sensor is defective or has shorted
• Internal engine components have become defective (e.g. bearings, oil pump, etc.)
  

What are the symptoms of the P0524 code?

The main symptom of this code should be the warning light we mentioned above. Your vehicle may also turn on the Check Engine light.

One symptom we also touched on above – and one you definitely don’t want to experience – would be a grinding in the engine or even smoke before your vehicle is no longer able to work. This is the consequence of too little oil in your vehicle.

How does a mechanic diagnose the P0524 code?

Diagnosis is pretty easy as this is one of the most common reasons people bring their car into a mechanic. They still may use an OBD-II scanner, though, just to make sure there aren’t any other codes that need their attention.

Then, they’ll pop the hood and remove the dipstick to see how much oil is left. If the code is stored, it’s probably a safe bet that more is needed.

Depending on how long the warning light has been on, your mechanic may also inspect the engine just to be sure no damage occurred from a lack of oil.

Common mistakes when diagnosing the P0524 code

When a lot of mechanics hear what warning light is on in your vehicle, they’ll immediately get to work dumping what’s left of the old oil and replacing it. However, as we pointed out above, there can also be plenty of other reasons for this problem. Even if more oil is needed, the oil pressure sensor could still be defective, so it’s worth looking into.

How serious is the P0524 code?

This is a very serious code because if you keep trying to drive without addressing it, your vehicle could quit working and it will cost a lot to fix it. In comparison, if all it takes is an oil change, you’re looking at a relatively affordable investment to keep your vehicle on the road. Don’t ignore this one.

What repairs can fix the P0524 code?

For the most part, no repairs are necessary. All your vehicle needs is a simple oil change. Otherwise, at most, a pressure sensor will need to be replaced or some wires may require repairs.

Additional comments for consideration regarding the P0524 code

If you plan on changing your own oil, be sure you dump whatever is left before proceeding.
