    Code P0544

    06 RXT threw P0544 code after launching. Ski was then ridden for 3 hours.
    Code states Exhaust Temp sensor.

    Can it be more anything more than that?

    thanks
    scott

    PS: friend's ski.

    No work has been done on the ski. The last time the ski was ridden not fault codes were present, fresh water. The ski was launched in salt water and shortly after the ski was put in the water it happened.

    Its my friend ski. Unfortunately I wasn't there at the time it happened. Knowing the tow vehicle and the ramp I am starting to wonder if he didn't back up far enough and drive to drive the ski off the trailer, heat up the exhaust and damaged the sensor or causedthe sensor to throw the code.

    Is that a valid hypothesis?

    Thanks to everyone sharing their ideas and experieince.

    it takes a lot of heat to melt those high temp sensors, mine melted after 12 or 13 high temp bleeps at WOT then blew the waterbox, it all stemmend from a partially blocked external intercooler, (full of lake weed)
