Question

2003 Toyota 4Runner 4.0L, could the bank 2 sensor 1 be causing this issue? code P0057

Answer 1

Hi there,

This code is for the heater in the sensor or the power wire or return to the computer. This code cannot be caused by the front sensor. If you have replaced the sensor and the problem or code is still there, you need to check the wiring for the sensor heater itself.

Answer 2

P0057 TOYOTA - Oxygen Sensor Heater Control Circuit Low Bank 2 Sensor 2
