P0155 Mitsubishi -

Question

where is the bank 2 sensor 1 oxygen sensor located?  I have read conflicting information from different websites.  I believe this sensor is located before the catalytic converter on the side of the transverse engine nearest the front bumper.

can an expert confirm this?  I have a P0155 error code and need to make sure I order the right sensor since there are 4 of them.

thx!

Hi there,

You are correct, the code is for bank 2 sensor 1. This is the side closest to the radiator and the first sensor prior to the catalytic converter.
