Nissan Xterra P0057 Fault Code After Catalytic Converter and Oxygen Sensor Replacement
After replacing the catalytic converter and four oxygen sensors on my 2005 Nissan Xterra, a P0057 diagnostic trouble code has appeared. I'm seeking clarification on potential causes and next steps to resolve this issue.
The P0057 trouble code indicates a failure in the heater circuit of Bank 2, Sensor 2 (O2 sensor) on the exhaust system. Potential causes include: physical damage to the heated oxygen sensor, a shorted control circuit or voltage feed to the sensor, or a failed oxygen sensor heater driver. It's also possible that improper installation or wiring during maintenance contributed to this fault. For more details, refer to official P0057 code explanations.
