Code P0057 2006 Infiniti G35 Description

The P0057 code for a 2006 Infiniti G35 specifically indicates an issue with the Heater Control Circuit of the HO2S22 sensor. The HO2S22 sensor is part of the vehicle's oxygen sensor system and is responsible for monitoring the oxygen levels in the exhaust gases. The heater control circuit is designed to keep the sensor at a specific operating temperature for optimal performance. When the control circuit is detected to be low, it means that the sensor is not heating up as it should, which can lead to inaccurate readings and affect the vehicle's fuel efficiency, emissions, and overall performance.

What does this mean?

Tech Notes for P0057 2006 Infiniti G35

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
