My 09 Escape is throwing the code for the Bank 2 Sensor 2 oxygen sensor. From what I've read, Sensor 2 should be behind the catalytic converter. The only 2 sensors I can see are the ones you can see under the hood behind the engine. Where would the bank 2 sensor 2 be located at? Thanks.

 

You need to get underneath to see the downstream sensors. Which code are you getting? If it’s P0430 it’s more likely there’s an exhaust leak or combustion problem causing the cat to operate outside normal limits.

 

I believe it was P013(can't remember the last number). It was for bank 2 sensor 2.

 

You need 1) the EXACT code (guessing doesn't work) and 2) identify your engine. If you have a 4-cylinder, B2S2 doesn't even exist. A P013x DTC refers to a bank 1 code anyway. It would have to be a P015xx to be bank 2.

 

It is a V6. The code was P013C. O2 Sensor Slow Response - Rich to Lean for Bank 2 Sensor 2.
