DTC P0139 HO2S Slow Response Bank 1 Sensor 2


Recommended Posts


In front of the catalytic converter.

Thanks Jim!

I am definetly going to leave this issue alone... Drove the car a little this evening and it was codeless.. yet another fit from my PCM i believe.. I do however want to figure out why the car stumbles when it is cold at take off everyday then clears up after 30 seconds... I am thinking faulty EGR valve... No codes of course.. Any idea's? This has done this for years before any issues with anything else..
