My service tire monitor light is on. Everything appears and sounds fine with the right front tire which it indicates is the problem. How do I fix or reset this?

    check the tire pressures and make sure they all match according to the drivers door placard.
    if the light persists, there may be a malfunction with the sensor itself.

    This might be a problem with the TPMS sensor itself. Take your vehicle to a reputable tire store and have them try to reset the system for you. If the TPMS system will not reset per the reset procedure, a sensor may have failed and need replaced.
