P0520 Jeep Error Code: Understanding and Troubleshooting with Methods A, B and the Zeus App

If you are encountering a P0520 error code on your vehicle, there are two straightforward DIY methods to resolve this issue. In this article, we will guide you through the process of fixing the error code at home using practical solutions.

Using the Zeus App to Identify the Error Code

The first step is to utilize the Zeus app to scan your vehicle and identify the error code P0520. This specific code indicates that the engine computer has detected a signal from the sensor that falls outside the manufacturer’s predetermined parameters, either being too high or too low.

Method A: Oil Change

The initial method involves performing an oil change on your vehicle. Here are the steps to follow:

  1. Locate the oil drain plug on your vehicle and position an oil collection pan beneath it.
  2. Use a socket ratchet to remove the plug from the oil pan and allow the oil to drain into the collection pan.
  3. After draining the oil, replace the drain plug and tighten it securely.
  4. Locate the oil filter, typically found near the oil pan or under the hood of your vehicle, and replace it with a new one. Remember to spread a bit of fresh oil evenly on the new filter’s gasket.
  5. Fill the vehicle with the specified amount of fresh oil as per the owner’s manual and start the engine to ensure the oil pressure is up.
  6. Check the oil level using the dipstick and add more oil if necessary. Dispose of the used oil appropriately at an auto store or recycling center.

Method B: The Oil Pressure Sensor

The second method involves addressing the oil pressure sensor:

  1. Remove the oil pressure sensor from your vehicle and inspect it for any damages. If damages are found, replace the oil pressure sensor.


By following these practical solutions, you can effectively resolve the P0520 error code on your vehicle. After completing the repair, use the Zeus app to clear the error code and rescan your vehicle to ensure everything is in proper working order.
