    There are multiple brake pressure transducers.

    Start at the base of the steering column. Pull the lower plastic.

    Other place depending is near the MV3 valve center of the dash.

    As @Goodysnap says RH lower side of the steering column.

    What is the issue?

    The issue was my traction control light on the dash had been on for over a month, took it to the dealer for diagnostic and they came up with the brake pressure sensor was corroded/bad...

    I didn't ask them any further details as I wasn't thrilled with the level of service I received from them...

    It was replaced for $600...............
