How does a mechanic diagnose a P0522 code?
When diagnosing this error code, a mechanic will do the following:
- Will clear all error codes and test drive the vehicle while monitoring the scanner data in real time to see if P0522 appears again
- Check the oil level and condition
- Check the oil filter for clogging
- Visually inspect the engine oil pressure sensor and check its wires and connectors for any damage
- Check the engine oil pressure sensor voltage using an ohmmeter and compare the value obtained with the value specified in the manufacturer's specifications
- Check the oil pressure using a mechanical pressure gauge and compare the obtained value with the sensor readings
Reasons for the error
Code P0522 may mean that one or more of the following problems have occurred:
- The engine oil pressure sensor is faulty.
- Excessive resistance in the oil pressure sensor circuit.
- Damaged, burnt, shorted or corroded wiring.
- Using the wrong engine oil.
- Poor maintenance, such as irregular oil and oil filter changes.
- Excessive mechanical wear of the engine.
- Mechanical failure of internal engine components such as oil pump, oil pressure relief valve. And also possibly timing chain tensioners or guides.
- Sometimes the cause is a faulty PCM.
What repairs can fix the P0522 code?
To resolve this error, the mechanic will do the following:
- Check for error codes using an OBD-II scanner, clear codes from the PCM, and test drive the vehicle to see if P0522 appears again
- Check and, if necessary, replace all damaged, loose, or shorted engine oil pressure sensor wires and connectors
- Check the voltage of the engine oil pressure sensor and, if necessary, replace it (the most common way to resolve the P0522 code)
- Eliminates problems caused by decreased oil pressure
Symptoms of malfunction
The main driver symptom of P0522 is the MIL (Malfunction Indicator Light) illumination. It is also called Check engine or simply “check light”.
They can also appear as:
- The “Check engine” warning light on the control panel will light up (the code will be stored in memory as a malfunction).
- Oil pressure warning light illuminated.
- When the engine is running, various mechanical noises may occur, which change as the rotation speed changes.
- Engine cylinders may misfire, especially if the problem is related to low oil pressure.
The P0522 oil pressure code is considered very serious, so it is recommended to fix this problem as soon as possible. For example, if the oil pressure is too low, it can cause the crankshaft and connecting rod bearings to seize.
The most common mistake
The most common error P0133 indicates the inability to fully accelerate
Please note that if the display shows error number P0133, we can conclude that the car has stopped accelerating well. This is due to the fact that the control oxygen sensor requires information about the concentration of the air-fuel mixture to be transmitted to the control unit. The sensor itself is located directly in the exhaust pipe, without touching the catalytic converter. The engine control unit is located behind the oxygen sensor when the closed-cycle operating time has passed. In addition, the composition of the air-fuel mixture itself is directly regulated by increasing or decreasing the pulses that occur when the injector opens.
Since most domestic car enthusiasts cannot afford to purchase a foreign car, the Lada Granta can easily play the role of a high-quality and complete replacement. Therefore, if any errors or malfunctions occur, the owner should find out the cause as quickly as possible and, if possible, try to fix the problem themselves. This will save not only time, but also very significant money that would have to be paid for contacting a service station.
System diagnostic methods
There are two ways to identify errors in Grant and its analogues. Both methods have clear advantages and disadvantages.
Self-diagnosis of Lada Granta
The principle of the method is to use standard systems installed on the machine. The procedure does not require connecting additional equipment or studying complex instructions. To perform the check, just follow a simple sequence of actions:
If, when switching to self-diagnosis, any indicators do not light up, their circuits must be checked first.
The disadvantage of this method is the low accuracy of the indicators. The display displays compressed information about the breakdown, which can only indicate the direction from which to start looking for the problem.
In the most popular versions of ECU firmware, network errors are noted as:
If “E” is displayed on the device, this indicates that the firmware is not working correctly.
Computer diagnostics
The next method involves connecting special equipment to the machine. The bottom line is this:
If everything is done correctly, special codes are displayed on the monitor. Moreover, each part of the code speaks of its own circuit.
The following are standard notations:
The next part indicates the serial number of the on-board circuit section where the breakdown is located:
Next comes another two-digit number - the last part of the index points directly to the system where there is a problem.
A little about the error
Error P0523, which is displayed by your on-board computer, indicates a malfunction of the engine oil pressure sensor (EOP). Its task is not to miss the moment of pressure drop, and there is hardly any need to explain how serious the consequences can be if your Lada Granta is not repaired in time.
The operation of the device is simple, but extremely useful. Inside it there is a membrane, which bends under the pressure of oil, while closing or opening the contacts. The contacts are connected to a warning light, which will immediately notify the driver if there is a lack of oil in the engine. So, your warning light may be on. The computer reminds you of error P0523. What could have led to this?
