Considering the fact that P0522 trouble code in the engine or other electronic systems of the car not always point directly to the faulty element and that different makes and models of cars the same error can occur as a consequence of failure of absolutely different elements of electronic system we created this algorithm of help and exchange of useful information.
We hope with your help to form the cause-and-effect relation of this or that P0522 trouble code in a particular car (make and model). As experience shows if we consider a certain make-model of the car, in the vast majority of cases the cause of the error is the same.
If the error indicates the wrong parameters (high or low values) of any of the sensors or analyzers, most likely this element is normal, and the problem should be sought in the so-called “upstream” in the elements whose work is analyzed by the sensor or probe.
If the error indicates a permanently open or closed valve, you need to approach the solution of the problem wisely and not mindlessly change this element. There can be several reasons: the valve is clogged, the valve is jammed, and the wrong signal comes to the valve from other malfunctioning nodes.
Engine operation errors P0522 TROUBLE CODE and other systems of the car (ELM327) do not always directly indicate a malfunctioning element. The error itself is an indirect data about the fault in the system, in a sense a clue, and only in rare cases a direct indication of a faulty element, sensor or part.
Errors (error codes) received from the device, scanner requires the correct interpretation of the information, so as not to waste time and money on replacing working elements of the car. The problem is often much deeper than it seems at first sight.
This is caused by the fact that the information messages contain, as mentioned above, indirect information about the malfunction of the system.
Here are a couple of common examples. If the error indicates incorrect parameters (high or low values) of any of the sensors or analyzers, most likely this element is normal, as it analyzes (gives out some parameters or values), while the problem should be sought “upstream”, so to speak, in the elements whose work is analyzed by the sensor or probe.
If the error indicates a permanently open or closed valve, then you need to approach the solution of the problem wisely and not mindlessly change this element. There can be several reasons: the valve is clogged, the valve is jammed, and the wrong signal comes to the valve from other defective nodes.
Another point that I would like to note is the specificity of this or that make and model. That is why when you find out about an error in the engine or any other system of your car do not make hasty decisions, but approach the question comprehensively.
Our forum is created for all users, from simple motorists to professional car electricians. A drop from each and all will be useful.
Description and meaning of error P0522
The ship’s main computer has caused the Powertrain Control Module (PCM) to control many sensors, controls, and electronics in the ship.
One of the sensors, called the oil pressure sensor or gauge, determines the amount of (mechanical) oil pressure in the engine and relays that as a value or voltage value to the PCM.
In some vehicles, this oil pressure value is then transmitted to a sensor in the dashboard to show the driver the oil pressure, in other cases that sensor does not exist, but there will be a warning light if there is a problem.
This specific Engine Code P0522 is caused when the PCM sees too low a value in the engine oil pressure meter/sensor. If the engine oil pressure actually drops too low, the engine can be permanently damaged, so if you notice low oil pressure, it is very important that you stop and shut down the vehicle as soon as possible.
For this alarm code, the cause is more than likely electrical-related. Note: this code is serious, you must act now to diagnose the repair. This code is related to all the trouble code such as P0520, P0521, P0523, and P0524.
Symptoms of error P0522
Symptoms of DTC P0522 may include: oil pressure gauge reading low or zeros Pressure Indicator Lamp illuminate engine can’t start or stall while controlling.
Possible causes of error P0522?
Shorted wiring to ground, engine oil pressure sensor, ECM Potential causes of code P0522 include: Faulty wiring or connection/connector in oil pressure servicer circuit faulty oil pressure servicer/ sensor open or short circuit in oil level wiring Low, improper oil, clogged oil passageway.
How do I correct error P0522?
There is a well-known service bulletin that applies to a number of GM vehicles, including Chevrolet, Cadillac, GMC, Pontiac, Buick, and Saab. Bulletin number-PIP4786.
Check for all the applicable Stabs (maintenance bulletins) for your vehicle even if it does not have one of those before going too far in the diagnostics.
There is also a TSB for some 2011 model year Chrysler Dodge cars where to fix the reprogramming of the PCM. First, and especially if you have other oil related DTCs, check the oil level status.
Make sure you have the correct oil type and weight and the oil filter is not clogged. Visually check the wiring and connectors on the oil pressure unit.
Look for broken or frayed wires, burned spots, loose or exposed wiring, etc. Refer to the model resource for the sender location. Do the same for the wiring and connectors leading to the PCM.https://www.youtube.com/embed/QIuR_5bYv04
Use a digital volt-ohm meter (DVOM) to check the sensor itself, and if it does not meet the manufacturer’s specifications, you must replace it.
This is a 5 volt circuit. Replacing the sensor/sender will be the most likely repair for this code. If it checks out okay, then test the wiring and connectors from the sensor to the PCM.
Make sure there are no breaks in the wiring or shorted ground due to chafing, pinching, etc. Make sure electrical connectors are tight and corrosion-free.
The technician can also put on a mechanical oil pressure gauge to check the actual oil pressure and compare that to the gauge reading using a preliminary reamer tool.
If your problem is not solved by fixing/replacing the wiring/sensor, check the actual engine pressure. As you can see, there are a number of possible causes for this P0522 code.
If the sending unit is cheap, then you could try replacing it first and see if that fixes it, but proper diagnosis definitely recommended so you are not replacing perfectly good parts. Good luck, if you need help stop by our car repair forum.
