where is bank 2 sensor 1 code P0154 on a 1996 silverado

Question

I have the part ready to install but I don't know what side or which sensor is the 1 to replace , also the autoparts guy checked for free and gave me the code P0154 and mentioned downstream. .

Answer 1

Hi there,

Bank 2 is the passenger side of the engine, sensor 1 is the pre converter sensor on that side of the engine. This is the upstream sensor, not the down stream.
