Code P0057 2012 Nissan Pathfinder Description

The P0057 diagnostic trouble code (DTC) for a 2012 Nissan Pathfinder refers to a malfunction in the Heater Control Circuit of the HO2S22 sensor. HO2S stands for Heated Oxygen Sensor, and the number 22 indicates that it is the sensor located downstream of the catalytic converter on bank 2 of the engine. This sensor plays a crucial role in 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.

What does this mean?

Tech Notes for P0057 2012 Nissan Pathfinder

The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.

When is the Code Detected?

The P0057 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit
