Code P0058 2014 GMC Sierra Description

The P0058 diagnostic trouble code (DTC) for a 2014 GMC Sierra refers to a problem with the HO2S (Heated Oxygen Sensor) Heater Control Circuit High Voltage for Bank 2 Sensor 2. This sensor is located downstream of the catalytic converter on the second bank of cylinders in the exhaust system. The HO2S 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.

Tech Notes for P0058 2014 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.
