The Isuzu Code P0522 is an error code associated with the Engine Oil Pressure (EOP) Sensor Circuit Low Voltage. It is an issue that needs to be addressed quickly, as it can cause significant problems to the engine, leading to costly repairs. To understand the cause and solution of this issue, it is essential to first look at the underlying components involved. The engine is running with engine speed between 1,000 and 3500 RPM, and the oil temperature is less than 140°C (284°F). In addition, two other error codes, P0641 and P1635, must not be present. When the ECM detects that the EOP sensor signal circuit is less than 0.4 volt and this condition is current for greater than 9 seconds, the Isuzu Code P0522 is thrown. To resolve this issue, it is essential to check the EOP sensor circuit for an open or short and replace the EOP sensor.
Possible Solutions: The possible solutions include checking the EOP sensor circuit for an open or short and replacing the EOP sensor.

Causes and Solutions of Isuzu Code P0522
| Causes | Solutions |
|---|---|
| ECM detects EOP sensor signal circuit is less than 0.4 vol | Check the EOP sensor circuit for an open or short |
| The above condition is present for greater than 9 seconds | Replace the EOP sensor |
| P0641 and P1635 are present | Replace the EOP sensor and check the error codes |
| Oil temperature is greater than 140°C (284°F) | Replace the temperature sensor and check the oil temperature |
Checking the EOP Sensor Circuit
The first and most crucial step in resolving the issue is to check the EOP sensor circuit for an open or short. This can be done using a multimeter to measure the circuit’s voltage. The course will likely be available or fast if the voltage is less than 0.4 volts.

Replacing the EOP Sensor
The next step is to replace the EOP sensor. It is essential to use a genuine Isuzu EOP sensor, as this will ensure that the sensor is compatible with the vehicle. Once the sensor has been replaced, resetting the ECM and checking for other error codes, such as P0641 and P1635, is essential.
Oil Temperature Sensor
If the oil temperature is more significant than 140°C (284°F), it is essential to replace the temperature sensor. This can be done by disconnecting the sensor, replacing it with a new one, and then reconnecting it to the engine. Once the sensor has been replaced, it is essential to check the oil temperature regularly and ensure it does not exceed 140°C (284°F).
Conclusion
The Isuzu Code P0522 is an error code associated with the Engine Oil Pressure (EOP) Sensor Circuit Low Voltage. To resolve this issue, it is essential to check the EOP sensor circuit for an open or short and replace the EOP sensor. Furthermore, replacing the temperature sensor is essential if the oil temperature is more significant than 140°C (284°F). Taking the necessary steps to address the Isuzu Code P0522 will ensure the engine runs smoothly without further issues. The key to successfully resolving Isuzu Code P0522 is to take the required steps quickly and accurately.
