My fan is inoperative and I'm getting a blink code 42 which the owners manual says is: "coolant temp low voltage". The service manual says something different "Engine Temperature Sensor Circuit: Short To Ground". Unfortunately, I don't know what either one means so I'm hoping someone can tell what needs to be repaired. The fan doesn't run when I disconnect the thermistor either. The machine has 190 miles on it and it's overheating after short rides.
