    Suddenly lt rear tire not registering on TPMS. Battery checks out ok in the tire pressure sender on obdi code reader but no registering in car. Is there a recalibration button in 458 like the 430 had? Or should I change out the sending unit for new in the left tire? The other 3 tires read fine. Thanks for help.

    The TPMS batteries only last 5-8 years. If one is gone, likely need to change all four unless they are fairly new.

    The code reader says the batteries are okay, and have a few years life in them. Should I have to change them anyway? Or is there some error with the code reader? Thanks

    There are other things that can cause a sensor to not register, like a problem with the antennas in the wheel-wells. Any good wheel and tire shop will have a TPMS tool that may be able to diagnose the problem.
