Which o2 sensor to replace
Hello fellas ! I pulled 2 codes off my reader P0136/P0138 (Bank I Sensor 2). How do I know which o2 sensor to replace ? I also read somewhere that these codes can be due to a faulty MAF or leaky gasket in the throttle body. I did just remove the throttle body and cleaned it up nice (due to a different code) and used sensor cleaner on the MAF so I'm a little concerned because the new codes came up a couple of days after I cleaned everything. I'll start with the sensor for now I just don't know which one to replace first. Any thoughts ? Your help is appreciated !
