    Check Engine-PO 116 code

    Hi, I have an 07 GTX LTD. and it has recently started showing Check Engine on the display with a code of PO 116 which according to http://www.sbtontheweb.com/forum/showthread.php?t=14562 shows "Engine temp sensor faulty". Is this the sensor that is on the front of the intake manifold near the IC? I'm 100 miles from a dealer so I thought I'd just buy a sensor and replace it but want to make sure I change the right one or does anyone think it could be something else causing the code besides a bad sensor? BTW, the ski seems to run fine. Thanks.

    I got this alarm too on my ski after I installed a Jim's Perf Modded plate. I was becuase I had a coolant leak(poorly installed connection on my part) and there wasn't enough coolant in the system. I would def check your coolant level first thing, then maybe run the ski in the hose long enough to see if the plate warms up(thus ensuring coolant flow) if that checks out its probably the sensor.

    Thanks Darth, it is full of coolant. No mods on this ski other than SC washers. FWIW the water temp. here is 80 degrees. This alarm kept happening yesterday and the water was pretty rough. I unplugged the sensor today and plugged it back on and went out and rode hard for 15 miles in smooth water and no alarm. Maybe just a bad connection on the sensor? Just trying to prevent having problems the next long holiday weekend. Thanks again!

    The engine temperature sensor is located in the rear of the engine on the top, right next to the large 1 1/2" coolant hose circulating through the head. Having a faulty sensor on the front of the intake manifold (the green sensor) will be 'intake manifold temperature sensor shorted to ground' P 0112.
