Question

I got a 2012 Honda Accord SE with error code P0135 for the check engine light

Answer 1

Hi there,

This code is for the heater circuit on the bank 1 sensor 1. On the 4 cylinder engine this is the first O2 sensor before the catalytic converter. In most cases the issue is with the sensor itself. If this is the 6 cylinder engine, then bank 1 sensor 1 is the first O2 sensor before the converter on bank 1
