So I have a 2010 Dragon RMK with a Aerocharger turbo and a HM Turbos fuel controller on it. My check engine light is flashing which I know is supposed to be the pipe sensor. Bought a new one which was 190 bucks or something and put it in and still flashing. So I figured that with my luck I got a faulty sensor so I took the one off my brother's 700 Dragon and installed it and still flashing. So then I took my old original sensor and put it on his sled and it didn't flash so my sensor was obviously fine. Could someone tell me what might be goin on??
