Error Code P0522: What It Means & What To Do?

<<See All OBD Codes

Is your Car’s Check Engine Light illuminating on the dashboard? Do you find sudden engine misfires? And is the car engine running rough with decreased performance? This might be the indication of problems with the engine oil pressure system of the car which in other words can be an OBD code P0522 error.

Error Code P0522 is defined as Engine Oil Pressure Sensor/Switch Low Voltage. This means the sensor is indicating that the oil pressure value is too low, which is due to faulty sensor, faulty sensor circuit or low oil level.

The PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) is the main computer of the vehicle which takes control of many electronics, sensors and controls within the vehicle, especially the engine. One of these sensors that the PCM controls is the oil pressure sensor or sender, and it detects the amount of oil pressure in the engine, relaying that information in the form of voltage reading/value to the PCM. For some vehicles, the oil pressure value is then relayed to a gauge into the instrument cluster to show oil pressure to the driver. Other times, the gauge is not there, but there will be a warning light should there be a problem.

Error Code P0522 gets triggered when the PCM detects a voltage that is lower than normal coming from engine oil pressure sensor. If the engine oil pressure actually drops too low, it can cause permanent damage to the engine. Thus, if you notice this error code, or a low oil pressure condition in your vehicle, it is crucial that you pull over and shut the engine off as soon as possible.

What causes this problem with the Engine Oil Pressure Sensor/Switch Low Input?

• Wiring or connection/connector in the Oil Pressure Sender Circuit faulty
• Oil Pressure Sender/Sensor failure
• Open or short in circuit wiring
• Low Oil level, use of wrong Oil, Oil Passage blockage
• Connector in the Oil Pressure Sensor Circuit faulty

1. Hoses & Fittings - Check for damaged oil hoses that might need replacement. Buy new parts and fittings now!
2. Oil Pressure Sensor - Inspect for faulty oil pressure sensor and replace it immediately as it can relay information wrongly to the PCM, causing performance issues.
3. Oil Pump - Oil pump can be clogged and damaged and should be repaired or replaced as per necessity. Buy new oil pump from us.
4. Oil Pressure Sender - If the oil pressure sender is faulty, replace it immediately. Buy new sender from us and replace now!
5. Powertrain Control Module - PCM issues directly affects the engine control and transmission control module. Thus, replace faulty components now.
6. Diagnostic Tool - Find wide range of diagnostic tools to detect and correct the OBD code error.

Willing to know some common symptoms of OBD Code P0522? Your wish is our demand. Have a look at them below:

Common Symptoms

• Check Engine Light illumination
• Engine may be shut down by the PCM
• Ticking, thudding, knocking, or rumbling sounds that change as the engine speed changes
• Engine may misfire, especially if the problem is an actual low oil pressure condition

We have listed out some ways which would help you to correct the occurrence of OBD Code P0522. They are mentioned here as follows:

• Replacement of oil pump
• Replacement of oil pressure sender
• Replacement of oil pressure sensor
• Replacing damaged hoses, wiring and connectors

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Oil Pressure Sender Circuit, Oil Hoses, Oil Pressure Sensor and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• A suitable OBD-II scanner (or code reader), a digital volt/ohmmeter, and a manual oil pressure gauge will be most helpful in performing a successful diagnosis. Begin with a visual inspection of all wiring and connectors.
• Repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and components as necessary. Always retest the system after repairs are completed to ensure success. If all system wiring, connectors, and components (Including fuses) appear to be in normal working order, connect the scanner (or code reader) to the diagnostic connector and record all stored codes and freeze frame data.
• This information can be extremely helpful in diagnosing intermittent conditions that may have contributed to this code being stored. Continue by clearing the code and operating the vehicle to see if it returns. This will help to determine whether or not the malfunction is intermittent. After the codes are cleared, test drive the vehicle to see if the code returns. If the code fails to immediately return, you may have an intermittent condition.
• Intermittent conditions can prove to be quite a challenge to diagnose and in extreme cases may have to be allowed to worsen before a correct diagnosis can be made. If engine oil pressure is excessive, suspect a faulty oil pressure sensor or clogged oil filter. Make sure that the engine is filled to the proper level with suitable engine oil. To diagnose the low oil pressure condition, connect the scanner or code reader and make a note of all stored trouble codes and applicable freeze frame data. Clear the codes and shut the engine off. Connect the manual oil pressure gauge to the engine.
• Start the engine and check for leaks. Allow the engine to reach normal operating temperature and make a note of the actual oil pressure reading at idle, 1,200 RPMS, and 2,500 RPMs. Compare your findings with manufacturer’s specifications and repair open or shorted wiring as necessary. PCM failure is rare as a cause of this condition.

Common Mistakes When Diagnosing the P0522 Code

• Clogged or damaged oil filter not checked
• Damaged or contaminated oil sender replaced
• Faulty oil pressure sensor not examined
• Not checking for oil hoses leaks
• Powertrain Control Module (PCM) replaced without doing proper diagnosis
• Wrong engine oil used in the vehicle
