QuestionQUESTION: Where is the coolant temp sensor and air temp sensor located.
What are the voltage ranges for each to run in closed loop mode.
ANSWER: why are u asking this u cant see the voltage ne way with out a scanner. And the range will depends on the outside air for the air temp sensor. the coolant temp sensor will show to be good if the inside gauge is working correctly.

QUESTION: where are the sensors located. I am building a potentiometer to intercept the voltage and fool the computer. I have covered the oxygen sensors. Some newer vehicles have air/fuel censors. I am getting 34 miles per gallon with my system but if I can control the coolant temp and air temp I think i can get more. I will have all the side work you can handle just with the current system. I can double fuel mileage on several vehicles but some require controlling the other sensors.
The air temp on my multimeter runs around 500 millivolts when fully warm in closed loop mode. I believe the coolant sensor starts at 5 volts cold and ends up at 500 millivolts hot. I need the location because its not on the thermostat housing.
Answerits right under the AC compressor u might need to remove the compressor to get access to it.The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature decreases, resistance (voltage) in the sensor increases
DO u work in ATL
