CHT Sensor readings and question.
EDIT: My CHT sensor is a modern 2 wire
So, had major problems on the road. Got the car home and here is where I think the problem lies. When cold the CHT was showing 2.11 which is in specs (1.4 - 3.6 ohms) When I barely warmed up the engine I was getting .203 which seemed at least I was going in the right direction. Still the car was nowhere near 105-175 degrees so this seemed off. I decided to let the car idle for a while and got the temp close to 194F/90C per dash/gauge and the reading I got was 99.1 all the way up to 118, which is quite away from the .150 to .300 I was expecting. Has anyone had these kind of readings before??? These are what I was using for comparison: ![]() ![]() If I am reading things right it would seem my sensor is going completely in the wrong direction I know these fail but can these technically fail this far off? I am looking into making a resistor for my on the road kit per old threads and carry that, DME and other bits all the time. Hopefully someone with similar experience can chime in. Thanks! Erik
