coolant sensor problem
i am working out the gremlins I inherited in a 2000 f350 7.3. 110,000 miles automatic tranny.
With the genisys scan tool the coolant temp is reading -40 degrees although the gauge on the dash shows the sensor working properly. I also shot the engine with a temp gun at operating temp. and it was in the 180 range.
So I think the sensor on the front of the engine tells the gauge on the dash whats going on, Does anyone know what tells the computer what is going on? I think if I find that info I will find out why I get the false reading from the scan tool.
I just did a quick search and found that the pcm doesn't mointor the engine coolant temp on the automatic transmission. Is the good info?
