Have you tried cleaning the sensor and the electrical connection? I gave mine a thorough cleaning and coated the electrical connection with dielectric grease and it hasnt acted up since...knock on wood. At last check the A/C sensor was 150 and the Kymco sensor was 55, it weighs less than one lb and will fit in a cigarette pack, no way shipping will cost 90 bucks. I WOULD try another dealer. For 150 bucks I wouldnt bother fixing it!
Yes, I did the same as you did but it still doesn't work. The problem is, there's only one Kymco dealer that is close to me. They are the ones that talked me out of ordering the Kymco sensor, because they don't want to sell the wrong part. My OEM # is supposed to be 3313-172 and I couldn't find the Kymco cross reference, nor could they. Arctic Cat (Thief River Falls) is about 2 hrs north of me, so he said there wouldn't be any shipping on the AC sensor. I've found an aftermarket one online for about $110.
