Code P0054 2016 GMC Sierra Description

The P0054 diagnostic trouble code (DTC) for a 2016 GMC Sierra refers to an issue with the HO2S (Heated Oxygen Sensor) Heater Resistance for Bank 1 Sensor 2. This sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. The heater element in the sensor helps it reach operating temperature quickly for accurate readings.

Tech Notes for P0054 2016 GMC Sierra

The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it takes the sensor to warm up and start sending an adequate signal. The code is set when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can cause the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the fuse and connector are OK, replacing the O2 Sensor usually takes care of the problem.
