    Your talking about the pressure sensor on the manifold? I killed one but I think I over boosted it with my turbo when I was dialing it in.

    The one on the front of the manifold. Its a temp sensor. The old ones were green, the new ones are blue. Leaking IC's are what used to kill the old green ones, but the new, blue ones I though were not supposed be killed by water.

    I had a green one go bad a couple of years ago. Bought another green one and it went bad about a month ago. Got a blue one this time. Well today, I am getting a check engine, when I pull up the code p0113, Manifold temp sensor.


    Fault P0113
    Descrption Intake manifold temp sensor shorted to 12V or voltage too high

    I've posted this chart and how to test in the past... (picture attachments below)

    The MATS (and CTS) sensors are really easy to test. All you need is a multimeter!

    The new sensors are now impervious to the elements but like anything, they can fail. But if they fail its not because you get water on them from normal IC condensation or leaking IC. They are just a thermistor shrouded in a brass casing - full metal jacket

    really easy ....if you not have a suspension model!
    Otherwise it takes a lot of work, because without removing
    the engine compartment cap (before lift up the moving deck from behind) - you will not get a
    single finger on to the sensor

    You can't even access the wires that run to the ECM?....you can test the wires from there (disconnecting the ECM harness)

    ECM connector "A" H3-White/Gray & J3-Black/White

    Yeah no kidding, I will never own a ski I can't work on. No amount of suspension is worth the hassle (unless just a basic tune).
