Code P0522 2016 GMC Sierra Description
When the diagnostic trouble code P0522 appears on a 2016 GMC Sierra, it indicates an issue with the engine oil pressure sensor circuit registering low voltage. This sensor is responsible for monitoring the oil pressure in the engine, providing crucial data to ensure proper lubrication and performance. A low voltage reading can signal a potential problem with the sensor itself, the wiring connected to it, or the engine's oil pressure. If left unaddressed, this issue can lead to inadequate lubrication of engine components, which may result in engine damage, decreased performance, and even engine failure.
Common Causes of P0522 2016 GMC Sierra
- Faulty engine oil pressure sensor
- Wiring or connector issues in the sensor circuit
- Low engine oil level or degraded oil quality
- Engine oil pump malfunction
- Engine mechanical problems affecting oil pressure
Symptoms of P0522 2016 GMC Sierra
- Illuminated oil pressure warning light on the dashboard
- Fluctuating oil pressure gauge readings
- Engine knocking or tapping noises
- Engine performance issues, such as reduced power or rough idling
- Oil leaks around the oil pressure sensor
How to Fix P0522 2016 GMC Sierra
- Begin by checking the engine oil level and quality, topping it up or replacing it if necessary.
- Inspect the wiring and connectors connected to the oil pressure sensor for any damage or corrosion, repairing or replacing them as needed.
- Test the engine oil pressure sensor using a multimeter to determine if it is functioning properly. Replace the sensor if it is faulty.
- Check the engine oil pump for proper operation and replace it if it is malfunctioning.
- If the issue persists, perform a thorough inspection of the engine to identify any mechanical problems affecting oil pressure, such as worn bearings or a clogged oil filter.
Cost to Fix P0522 2016 GMC Sierra
The typical repair costs for addressing a P0522 code on a 2016 GMC Sierra can vary depending on the specific cause of the issue. On average, the cost of parts for replacing the oil pressure sensor and associated components can range from $50 to $200. Labor costs can add another $100 to $200, depending on the shop's hourly rates and the complexity of the repair. It's important to consider additional diagnostic time and potential costs for addressing any underlying engine issues that may be contributing to the low oil pressure reading.

Frequently Asked Questions about P0522 2016 GMC Sierra Code
What does the OBDII code P0522 mean on a 2016 GMC Sierra?
The P0522 code indicates that the Engine Control Module (ECM) has detected a low voltage signal from the engine oil pressure sensor, which monitors oil pressure levels.
What are the common symptoms of code P0522 in a 2016 GMC Sierra?
Symptoms can include the engine oil pressure warning light turning on, inaccurate oil pressure readings on the gauge, engine performance issues, and in some cases, engine knocking.
What causes the P0522 code to appear on my 2016 GMC Sierra?
Common causes include a faulty oil pressure sensor, low engine oil levels, damaged wiring or connectors in the oil pressure sensor circuit, or a failing ECM.
Can I continue driving my 2016 GMC Sierra with the P0522 code?
Driving with this code is not recommended as it could indicate low oil pressure, which may lead to severe engine damage if not addressed promptly.
How do I diagnose the P0522 code on my 2016 GMC Sierra?
Diagnosis typically involves checking the engine oil level, inspecting the oil pressure sensor and its wiring for damage, and using a scan tool to monitor sensor readings.
How do I fix the P0522 code on my 2016 GMC Sierra?
Repairs may include replacing the oil pressure sensor, repairing or replacing damaged wiring, ensuring proper oil levels, and in rare cases, addressing ECM issues.
Can low engine oil cause the P0522 code on a 2016 GMC Sierra?
Yes, low engine oil levels can result in low oil pressure, which may trigger the P0522 code.
How much does it cost to repair the P0522 code on a 2016 GMC Sierra?
The cost can vary, but replacing the oil pressure sensor typically costs between $100 and $300, including parts and labor.
What tools are needed to replace the oil pressure sensor on a 2016 GMC Sierra?
You will need a ratchet, an oil pressure sensor socket, and possibly a torque wrench to replace the sensor properly.
Can a dirty oil filter cause the P0522 code on a 2016 GMC Sierra?
Yes, a clogged or dirty oil filter can restrict oil flow, potentially causing low oil pressure and triggering the P0522 code.
