Heated oxygen sensor

so if you don't tell us we can't give an answer we need to know what the code is

Im sorry, po135 bank1 sensor1

this can be a sensor bad, ecm or a short in system try replacing sensor first as it's the heater element and may have burnt out. that is cheapest fix then reset computer and if light goes back on then you can delve into it further.

info is right but it is on the rh side of engine before the converter.

Thank you very much I'm going to pick
Up a sensor now I'll let you know.
Thank you again
