I have a 2017 ZForce 800 Trail. Last weekend while trail riding, my ZForce had gotten rained on during the night-heavy rain too. The next day when we went to go riding, it will start but only if I give it some gas pedal. It will run fine as long as i give it some gas. There is no idle at all. Went thru the system check and the codes say low voltage to the TPS sensor. It has 4.8 vdc. Manual says it should be 5.0 vdc. I have checked everything I can think of-drained the gas, pulled all the connections apart and let it sit out in the sun-changed the fuel filter behind the air box-cleaned the filter. Tapped on the fuel pump. Any help on this would really be appreciated.
