Code P0522 2018 Chevrolet Silverado Description

The engine oil pressure sensor changes voltage based on the engine oil pressure. The engine oil pressure sensor is a 3-wire sensor comprising the signal circuit, the low reference circuit, and the 5 V reference circuit. The Engine Control Module (ECM) supplies 5 V to the engine oil pressure sensor via the 5 V reference circuit and provides ground via the low reference circuit. The ECM monitors the signal circuit of the engine oil pressure sensor to determine if the engine oil pressure sensor voltage is within the normal operating range of approximately 1 - 4 V. When the engine oil pressure is high, the engine oil pressure sensor voltage is high, and the ECM senses a high signal voltage. When the engine oil pressure is low, the engine oil pressure sensor voltage is low, and the ECM senses a low signal voltage. The ECM sends the engine oil pressure information to the instrument cluster via serial data. The instrument cluster will illuminate or display the engine oil pressure indicator when the engine oil pressure is low. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the engine oil pressure sensor signal circuit is less than 0.2 V for greater than 10 s.

Frequently Asked Questions about P0522 2018 Chevrolet Silverado Code

What does the OBDII code P0522 mean for a 2018 Chevrolet Silverado?

Code P0522 indicates that the engine oil pressure sensor is detecting a voltage level that is lower than expected, which may suggest an issue with the sensor, wiring, or oil pressure.

What are common symptoms of code P0522 on a 2018 Chevrolet Silverado?

Symptoms may include an illuminated check engine light, oil pressure warning light, inaccurate oil pressure readings, and potential engine performance issues.

Can driving with code P0522 damage the engine?

Yes, driving with code P0522 can be risky because low oil pressure can lead to insufficient lubrication, potentially causing severe engine damage.

What are common causes of code P0522 on a 2018 Chevrolet Silverado?

Common causes include a faulty engine oil pressure sensor, damaged or corroded wiring, low engine oil levels, or issues with the oil pump.

How do you diagnose code P0522 on a 2018 Chevrolet Silverado?

Diagnosis involves checking the engine oil level, inspecting the wiring and connections to the oil pressure sensor, and testing the sensor itself for proper function.

Can low engine oil trigger code P0522?

Yes, low oil levels can cause the sensor to detect low pressure, which may result in this code being stored.

How can code P0522 be fixed on a 2018 Chevrolet Silverado?

Repairs may include replacing the engine oil pressure sensor, fixing damaged wiring, topping off or changing the oil, and addressing issues with the oil pump if necessary.

Is replacing the engine oil pressure sensor difficult?

Replacing the sensor is typically straightforward, but it may require specialized tools and access to the sensor's location on the engine.

Can a faulty oil pressure sensor affect engine performance?

Yes, a faulty sensor can lead to inaccurate oil pressure readings, potentially triggering limp mode or causing engine performance issues.

How much does it cost to fix code P0522 on a 2018 Chevrolet Silverado?

Repair costs can vary but typically range from $100 to $300, depending on whether the sensor, wiring, or other components need replacement.
