Diagnostic Code P0522: Engine Oil Pressure Sensor/Switch Low Input

We know you came here searching for the answer to "how do I fix trouble code P0522?" We aim to answer that question, but first, it is necessary to understand the meaning of the code as well as its causes and symptoms. With that said, let's begin.

What Does the Code P0522 Mean?

The oil pressure sensor or sender is used to detect the oil pressure in your vehicle’s engine. The information collected by this sensor is then sent as a voltage reading to the car’s main computer, the Powertrain control module. Also, some makes and models might have a separate gauge that lets the driver know the pressure. However, even when a gauge is not present, there will probably be a warning light to notify the driver when there is an issue with the standing oil pressure reading.

In regards to the trouble code P0522, when the Powertrain control module receives a reading from the oil pressure sensor that is too low, the code displays. When you notice an issue with your oil pressure, it is crucial that you find a safe place to pull off the road because the engine can be permanently damaged if forced to drive for too long in such a condition.

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. Also, there could be a short in the circuit wiring. Last, it is possible that the diagnostic trouble code is a result of a faulty sensor, meaning that there is actually nothing wrong with your oil or oil pressure. Therefore, it is essential to perform a thorough diagnostic check of your vehicle’s electrical components, ensuring that everything is operating correctly before assuming there is an oil-related issue.

Are There Any Symptoms?

Unfortunately, there are several symptoms of this error code, and most will require your car to spend time on the rack or in the shop. Some issues that might be electrical and have little influence over your drive are the illumination of the oil pressure indicator lamp or the oil pressure gauge reading low or zero. While these issues are alarming, they don’t necessarily speak to an engine problem because the wiring in the sensor could be to blame. However, if you experience problems with your engine starting, quitting or stalling, then you might have a severe problem that could be permanently affecting your engine’s operation.

What Is the Solution?

The first thing you will want to do when attempting to resolve this specific trouble code is to check the oil level and condition. Double-check the oil you purchased against the manufacturer’s recommendations. Also, inspect the oil filter, looking for clogs or heavy debris. If the oil and filter check out, then examine the connections and wires coming from the oil pressure sensor to the Powertrain control module, making sure that everything appears in place and good working condition. Additionally, using a digital volt ohm meter, check the output of the sensor against the manufacturer’s recommendation. If all of the above checks out, then it might be time to take your car into a licensed technician.

The OBD-II scanner error code P0522 problem can be a significant issue. However, the resolution might not be so easy, meaning that a professional with experience might be better than DIYing your way through the process, especially with the potential damage that can be done to the engine if left unchecked.
