Code P0152 2015 GMC Sierra Description

The P0152 diagnostic trouble code (DTC) for a 2015 GMC Sierra relates to the oxygen sensor circuit of Bank 2 Sensor 1 operating at a high voltage level. The oxygen sensor, also known as the heated oxygen sensor (HO2S), plays a crucial role in monitoring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) for optimal fuel delivery. In this case, the HO2S in Bank 2 Sensor 1 is reporting a voltage higher than the normal operating range, indicating a potential issue with the sensor or its circuit.
