Hello All-

The CEL on the wife's Rodeo has been on for a few months now and I am at my wits end. When the light came on I took it to Autozone and they told me that the front O2 sensors were bad, so I purchased Bosch replacements thinking that would fix the problem....I was wrong.

The light was back on in no time, so I took it to the dealership (<70K miles) just in case something else was wrong with it. They ended up replacing the intake gasket (warranty), but confirmed the right front O2 sensor was still not working. They wanted $262 to replace it, but I decided to do it myself since I had just put that one in. Autozone swapped out the sensor without question, but I still had the problem. I took it back to the dealer again and they gave me the same diagnosis. They suggested I use an Isuzu sensor, so I ponied up $110 for it......unfortunately the light came back on shortly after it was reset.

Any suggestions on what else could it be? Is there a fuse somewhere that needs replaced? Thanks for any and all input.
