engine code help

[darkagentL]

Hello all! Anyone deal with a P0054 code. Not showing up on the predator but the SES light keeps coming on. Autozone pulled the 0054 code bank 1 sensor 2 circuit bad? no reference to lean or rich condition. I checked all the wires at the sensors they look fine. Is there a fuse tied to that circuit? The truck is and has been running strong for a long time with no problems. I've reset the light a few times now and it keeps coming back. Think my O2's have crapped out? Truck has 48,000 on it. Thanks for any advice offered! :thumbsup:

It's the O2's Back sensor (Drivers side...I think)

Isn't bank 1 on the other side? Anyway there's nothing physically wrong like loose or broken wires. If it is an O2 sensor that's a little disappointing under 50k miles. I'll keep looking. May try cleaning the MAF. The exhaust seems a little rich.
