I'm getting P0135 and P1132 codes on an 01 f150. I have already changed the upstream 02 sensor on the drivers side. Anyone have any ideas?
TIA

 

Something's wrong with the wiring. Are the wires in good shape? Not melted? Is the inside of the connector clean (both male and female) ? Follow the wiring up as far as you can to see if there is any damage. (Cuts, melted insulation etc...)

 

Hi and welcome to the forum. I would check the sensor wiring. trace it back a ways. It may have rubbed a bare spot in it somewhere.
