The P0522 fault code indicates that the engine oil pressure sensor or switch is detecting a low voltage signal. This sensor plays a crucial role in monitoring the oil pressure within the engine, and a failure can lead to potential engine damage if not addressed promptly.

What are the symptoms of the P0522 code?

Typical symptoms associated with the P0522 code include:

• Warning light on the dashboard indicating low oil pressure
• Engine performance issues
• Odd noises from the engine due to inadequate lubrication
• Possible overheating of the engine if the oil pressure is not regulated properly

What causes the P0522 code?

Common causes of the P0522 code may include:

• A faulty engine oil pressure sensor
• Damaged wiring or connectors leading to the sensor
• Low engine oil levels
• Problems with the engine's oil pump
• A malfunctioning engine control module (ECM)

How to fix P0522?

To resolve the P0522 fault code, you may follow these steps:

• Inspect and, if necessary, replace the engine oil pressure sensor.
• Check for any damaged wiring or connectors and repair or replace them as needed.
• Ensure that the engine oil level is within the recommended limits.
• Test the oil pump for proper operation and replace if faulty.
• If the issue persists, consider consulting a professional to evaluate the ECM for possible faults.
