I replaced my Bosch O2 Sensor a couple weeks back as it had about 40K+ miles on it since the last change and I figured since my gas mileage had dropped a bit, and after doing any of the other things (distributor change, plugs, wires, new tires, air filter, etc....) this was the last thing that needed to be changed.
Flash forward to this week... and my Check Engine light has come on a couple times. Ran my code scanner and got codes P0148, P0138 & strangely... '00 8' and not sure what that is. I know that one of these is for the O2 sensor signals, but not sure the other two. This just started about 1 month after replacing the O2 Sensor w/another new Bosch Sensor.
Could I have just got a bad Sensor? I have the box the part came in, but not the receipt and doubt Autozone will exchange for me. I kept the 'old' O2 sensor so perhaps I should just swap that one back in and try my luck at exchanging and replacing.
Any suggestions? Could it be something else I need to check?
Appreciate the help.
