Code P0522 2016 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 2016 Chevrolet Silverado Code

What does the OBDII code P0522 mean for a 2016 Chevrolet Silverado?

P0522 indicates that the Engine Control Module (ECM) has detected a low voltage signal from the engine oil pressure sensor, which monitors the engine's oil pressure.

What are the common symptoms of code P0522 in a 2016 Silverado?

Symptoms may include the oil pressure gauge reading abnormally low, the oil pressure warning light coming on, engine performance issues, or, in some cases, engine noise due to low oil pressure.

What causes the P0522 code in a 2016 Chevrolet Silverado?

Common causes include a faulty oil pressure sensor, low engine oil level, contaminated oil, wiring issues such as damaged connectors or short circuits, or a failing ECM.

Can I continue driving my 2016 Silverado with a P0522 code?

It’s not recommended to drive with this code active as it may indicate low oil pressure, which can cause severe engine damage if not addressed promptly.

How do I diagnose the P0522 code on a 2016 Silverado?

Start by checking the engine oil level and condition, inspect the oil pressure sensor and its wiring for damage, and test the sensor's voltage signal with a multimeter.

How can I fix code P0522 in my 2016 Chevrolet Silverado?

Repairs may include topping off or changing the engine oil, replacing the oil pressure sensor, repairing wiring or connector issues, or addressing any deeper engine problems if oil pressure is truly low.

How much does it cost to fix code P0522 on a 2016 Silverado?

The cost varies but replacing the oil pressure sensor typically costs $100–$300, including parts and labor. Wiring repairs or other issues may increase the cost.

Can a dirty or old oil filter cause the P0522 code?

Yes, a clogged or old oil filter can restrict oil flow, leading to low oil pressure and triggering the P0522 code.

What tools are needed to fix the P0522 code?

Common tools include a multimeter for voltage testing, a socket wrench for sensor removal, and an OBDII scanner to read and clear the code.

Will clearing the P0522 code solve the issue in my 2016 Silverado?

Clearing the code will temporarily remove the warning, but if the underlying problem isn’t fixed, the code and symptoms will likely return.
