OK today I turned on the car and di not move it. I let it fully warm up in the driveway. I had my OBDII Bluetooth adapter plugged in, and I was monitoring the Coolant temperature with the Torque app. The coolant temperature reported by the Torque app seemed to track the dash gauge. I let the engine warm up to 219 degrees F, and still no fans came on.
I am wondering what else could be wrong. I recall from reading my FSM that if the car is moving at less that 40mph, and the temperature reaches 99C or 210F, the fans should come on full blast. Turning on the AC does work correctly (fans come on full blast).
I hope I have not cooked the tranny! I have solid 1st and reverse, but no 2nd or 3rd.
I am curious what the resistance should be at the 100 degrees F. I could pull the plug on the sending unit, and simulate temperatures.
