My FFH at ~63,000 miles has the "Service Engine Soon" warning light displayed. At first it was intermittent, now it is on all the time. I have no driving issues, I'm getting my normal 40-43 mpg.
When I have the codes checked at my local Advanced Auto store (free), they pull a P0130 code, and their OBDII readout says Oxy Sensor, Bank 1, circuit 1. Advanced shows that part costs $273 (I think it is electrically heated). Rockauto.com shows Oxygen sensors from $25 to $174 for the FFH, that suggest they are for the front bank, but some have oval and some have round connectors.
If there is anyone with FFH oxygen sensor knowledge here, please advise. I have had no other issues with the vehicle, and still don't for performance and driveability. Are emission items covered on any warranty other than the 3/36? I didn't get an extended warranty, and I'm not sorry about that yet.
