Question

2000 Ford Taurus 3.0L DOHC with code P0156

Answer 1

Hi there,

This code is for the bank 2 sensor 2 which is the O2 sensor AFTER the catalytic converter on bank 2. On this engine bank 2 is the bank closest to the radiator. The code is specific to the heater in the O2 sensor and in most cases the sensor itself is the problem.
