The sensor has a negative-temperature coefficient. Ensure it has enough but NOT over full. I get home and while idling the overdrive light flashes on for a second.
I ordered one from Honda but before it came I decided to spray all 3 the electrical connections on the tranny to make it easier to pull. The Automatic Transmission Fluid Temperature TFT sensor is a resistor or thermistor which changes value based on temperature. Use a small screwdriver to pry the connector from the oil temperature sensor.
The Transmission Control Module TCM supplies a 5V reference voltage to the sensor and the output voltage of the sensor changes when the ATF temperature varies. Discussion Starter 1 Feb 1 2009. Youll have to eyeball the new part and find that part on.
The FSM shows how to test it Then refers you to AT100 On Vehicle Replacement to remove it. Disconnect the oil temperature sensor connector A. Remove the bolts that secure the valve body cover and remove the cover.
