    TPS Issues

    A little something I learned today.

    Some Common TPS Failure Reasons

    Over torque of the TPS, use the torque specs and torque evenly so you don't crack the housing.
    Salt water corrosion, usually do to a broken or cracked housing.
    The connections at the TPS develop corrosion, it's important to hang the wires from the TPS so they do not pull or tug at the connector.

    The early TPS sensors (99-01) with the pig tails have an average life of 4 years.
    The newer style without the pig tails were the headaches, read above and take the neccessary precautions to help preserve your TPS.

    I am almost certain Bernie will have something to add here.

    Apparently salt water was also getting into the TPS where the 'sealed' wires entered the housing, on at least one TPS generation. And extra vibration with the two cylinder motors also seems to kill them faster (info from Bernie).

    So what is the average life of the current TPS design, since many of the original ones (average life of 4 years, from 2001) would likely be bad by now.
