What is the code for the oil pressure sensor?
As a seasoned auto repair expert at Kevin's Autos, I often get asked about the oil pressure sensor, a critical component in your vehicle's engine monitoring system. This article will explain what the oil pressure sensor does, why it’s important, and how to identify its code for replacement or diagnostics.
Understanding the Oil Pressure Sensor
The oil pressure sensor is a small but vital part of your car's engine. Its primary function is to monitor the oil pressure in the engine and send this information to the vehicle's computer or dashboard. If the oil pressure drops below a safe level, the sensor triggers a warning light to alert the driver. This helps prevent engine damage caused by insufficient lubrication.
Why You Might Need the Oil Pressure Sensor Code
When diagnosing issues with your vehicle or replacing the oil pressure sensor, you may need the specific part code. This code ensures you purchase the correct sensor for your car's make and model. Using the wrong sensor can lead to inaccurate readings or even damage to your vehicle's engine.
How to Find the Oil Pressure Sensor Code
Here are some steps to locate the oil pressure sensor code for your vehicle:
- Check the Owner’s Manual: The owner’s manual often includes part numbers for various components, including the oil pressure sensor.
- Inspect the Sensor Itself: If you can access the oil pressure sensor, it may have a part number or code printed on it. Be sure to clean the area around the sensor to make the code visible.
- Use an OBD-II Scanner: If your vehicle has triggered a warning light related to oil pressure, an OBD-II scanner can read the diagnostic trouble code (DTC). This code can help identify issues with the oil pressure sensor.
- Contact Your Dealer or Mechanic: If you’re unable to find the code, your vehicle’s dealership or a trusted mechanic can provide the correct part number based on your car’s VIN (Vehicle Identification Number).
Common Oil Pressure Sensor Codes
While the specific code for the oil pressure sensor varies by vehicle make and model, here are some common diagnostic trouble codes (DTCs) related to oil pressure sensors:
- P0520: Engine Oil Pressure Sensor/Switch Circuit Malfunction
- P0521: Engine Oil Pressure Sensor/Switch Range/Performance
- P0522: Engine Oil Pressure Sensor/Switch Low Voltage
- P0523: Engine Oil Pressure Sensor/Switch High Voltage
When to Replace the Oil Pressure Sensor
If you notice any of the following symptoms, it may be time to replace your oil pressure sensor:
- The oil pressure warning light stays on even when oil levels are adequate.
- The oil pressure gauge shows erratic or inaccurate readings.
- You experience engine performance issues, such as knocking or overheating.

Frequently Asked Questions
Can I drive with a P0521 code?
In some cases, the low oil warning light will illuminate. If the low oil warning light activates along with the check engine light, stop driving immediately and have your vehicle towed for repairs.
Will low oil cause oil pressure sensor code?
With the P0522 code, a low oil pressure issue like a low oil pressure condition will trigger the code. Faulty oil pressure sensors or damaged oil pumps can also cause any of these codes to be set.
How do I fix my oil pump pressure?
How do you fix low oil pressure? To fix low oil pressure, start by checking your oil level and topping it up if it's low. If the oil level is fine, the next step is to inspect and possibly replace the oil filter, as a clogged filter can restrict oil flow.
What would cause a P0522 code?
What Are the Causes of P0522? While this error code can appear when your car has low oil levels, the wrong oil or an oil blockage, the most likely culprit is electrical. Therefore, you might be experiencing a faulty wire or connection in the circuit for the oil pressure sensor.
How to fix oil pressure sensor code?
The P0520 and its related codes can be inspected by replacing the oil pressure sensor with a new sensor. This is the most common repair, followed by repairing any faulty wiring, connectors, or oil pressure gauges. Sometimes, a simple oil change and a new oil filter are needed.
What is the code for the engine oil pressure sensor performance?
P0521
P0521 indicates that an irregularity has been detected in the sensors that monitor oil pressure in your vehicle. In some instances, this means that the value of oil pressure has remained fixed for too long, or that an abnormal amount of pressure (or lack thereof) has been read by your car's computer.
What happens if you keep driving with a P0522 code?
Engine may quit or stall.
Can I drive my car with a faulty oil pressure sensor?
Avoid driving your car until you fix this problem, since operating with low oil can be dangerous.
Will a bad oil pressure sensor hurt your engine?
Oil pressure sensors go bad and eventually fail. When this happens, the dashboard light can become constantly illuminated. It can also cause an oil leak. If you keep driving your vehicle, you'll cause significant damage to your engine.
How serious is a P06DD code?
Additionally, issues with the P06DA, P06DD, and P06DE codes have to do with a problem surrounding your oil system, which can result in engine damage and even engine failure — loss of oil pressure is one of the quickest ways to seriously damage an engine.
