What does the P0522 code mean?
The P0522 code is a diagnostic trouble code that indicates a problem with the engine oil pressure sensor circuit. The engine oil pressure sensor is responsible for monitoring the oil pressure in the engine and sending this information to the engine control module (ECM).
The ECM uses this information to adjust the engine oil pressure and maintain the correct oil pressure for optimal engine performance. If the ECM detects a problem with the engine oil pressure sensor circuit, it will trigger the check engine light and display the P0522 code on the dashboard. To put it simply, it means that the sensor may not be able to provide accurate readings of the oil pressure, and this may lead to further complications related to the engine’s performance.
What causes the P0522 code?
There are several potential reasons behind the code P0522 being displayed on the diagnostic tool. Some of the main symptoms that follow these codes are trouble starting the engine, issues with the lower oil pressure, and even misfires. Here are some of the main causes of this issue:
Faulty engine oil pressure sensor
A faulty engine oil pressure sensor is one of the most common causes of the P0522 code. Over time, the sensor can become clogged with debris or may fail completely, resulting in inaccurate readings or a lack of readings altogether.
Wiring issues
Wiring issues can also cause the P0522 code to appear. Loose or damaged wiring can prevent the engine oil pressure sensor from sending the correct signals to the ECM.
Low oil pressure
Low oil pressure can also trigger the P0522 code. A lack of oil pressure can cause serious damage to the engine and other components, so it is important to address this issue promptly.
Which car models does the P0522 code affect the most?
While the P0522 code can appear on any vehicle, some car models are more prone to this issue than others. The code typically appears on vehicles with high mileage or those that have been driven in extreme conditions. Some of the car models that are most affected by the P0522 code include:
- Dodge RAM: This pickup truck is known for its powerful engine and towing capacity, but its oil pressure sensor is prone to failure, which can trigger the P0522 code.
- Jeep Wrangler: The popular off-road vehicle has a history of oil pressure issues, which can cause the P0522 code to appear.
- Chrysler 300C: This luxury sedan has been reported to have problems with its oil pressure sensor, leading to P0522 code warnings.
How to diagnose the P0522 code
Besides using a scanner tool to diagnose the code, there are several other ways in which you can get to the bottom of what’s causing the issue. So, we advise you to apply one of the following methods to figure out the source of the problem:
Check the engine oil
The first step in diagnosing the P0522 code is to check the engine oil level and quality. Low oil pressure can be caused by low oil levels or dirty oil. If the oil level is low or the oil is dirty, it is important to change the oil and filter and monitor the oil pressure.
Check the engine oil pressure sensor
If the oil level and quality are good, the engine oil pressure sensor should be checked. The sensor can be tested using a multimeter to check for continuity and resistance.
Check the wiring
If the sensor is functioning properly, the wiring should be checked for any loose or damaged connections. All wiring connections should be checked to ensure they are properly connected and not damaged.
Check the oil pump
If the wiring is functioning properly, the oil pump should be checked to ensure it is working correctly. The oil pump should be checked for blockages or damage.
How to fix the P0522 code
Once the cause of the P0522 code has been identified, it is important to address the issue promptly. Some potential fixes for the P0522 code include:
Replace the engine oil pressure sensor
If the engine oil pressure sensor is faulty, it should be replaced. A new sensor can be installed by a professional mechanic or DIYer.
Repair or replace wiring
If the wiring is loose or damaged, it should be repaired or replaced. This can usually be done by a professional mechanic.
Replace the oil pump
If the oil pump is damaged or blocked, it should be replaced. This is a more complex repair that should be done by a professional mechanic.
How to prevent the P0522 code
The best way to prevent the P0522 code is to perform routine maintenance on your vehicle. This includes the following methods:
- Change the oil and the filters regularly
- Checking the oil level and quality
- Making sure that all the wiring and connections are at bay
You should also stick with the manufacturer’s recommended servicing requirements so you can ensure that your vehicle is at a lower risk of being plagued by the code P0522.
Our take
Overall, it’s not as easy to deal with the code P0522 as it may seem, but that doesn’t mean you should delay dealing with the problem. The best thing to do is to uncover the reason behind the code’s activation and fix or repair the faulty components that lead to it so you can drive safely again.
That’s where our guide may become helpful and we hope you won’t have to deal with the issue ever again if you hold on to our recommended prevention methods.
How serious is the P0522 code?
While the P0522 code itself is not likely to cause immediate harm to your vehicle, ignoring it could result in more serious engine problems over time.
How can I prevent the P0522 code?
Regular maintenance is key to preventing the P0522 code and other engine-related issues. This includes changing the oil and oil filter regularly, checking the oil level and quality, and ensuring all wiring connections are secure.
Can I still drive my car if the P0522 code appears?
It depends on the severity of the problem. If you notice any unusual symptoms such as engine knocking or stalling, it’s best to stop driving your car immediately and seek professional help. Otherwise, you may be able to continue driving your car until you can have it inspected by a mechanic.
