    07 5.7L Long bed 210k. my battery terminal recently separated from the battery, it gets loose at times. So, I have a few codes, besides the TPMS sensors. I've been running this OBD2 reader and this is the first time I've run into these 4 codes. Interesting 3 airbag codes and another under the TPMS sensor codes. I may give it a couple days just to make sure there is no real issue, just the whole ECU/PCM running checks after a reset. Here are the 4 codes.

    Is this related to an O2 sensor?? I recently replaced my starter, and no I didn't remove the exhaust
    P2476 Exhaust Gas Temperature sensor circuit high bank 2 sensor 4

    I may need to troubleshoot this under my seat, I didn't see any SRS airbag light on the dash, which I still think its a ECU/PCM running checks down the system. When I ran this diagnostic I had my door open and wasn't wearing my seatbelt, which I don't think make a difference, but I need to check under my seat, regardless.
    B1653 is stored when a malfunction is detected in the seat position airbag sensor circuit.
    B1655 Driver Side Seat Belt Buckle Switch Circuit Malfunction
    B1821 Open In Side Squib - Right Circuit'

    Any one else have these issues??

    On hindsight, these B codes may be for my Celica.... LOL... It just dawned on me, that I haven't plugged in my driver side seat sensor encompassing the B codes. I'm still confused on the P2476. EGT portion, may have to reset the scanner and re-scan the Tundra, so for now I'm confirming the B codes are not relevant. I'll need to research further the P2476, last time I touched that sensor was about 6 months ago when I swapped out my starter. I'll have to re-check its connection, if not replace the sensor altogether.
