The coolant temp sensor provides input to the fuel control system. What symptoms are you experiencing? Are the readings on your gage inconsistent with what you feel the engine operating temperature is. Is it showing high temps for a cool engine, or low temps for a hot engine?
Yes. the gauge says the car is cold but i have been driving the cat for over an hour and the gauge still reads cold.I also have been experiencing bad gas mileage...Have changed the following sensors IAC,TPS,O2, cam, crank the only one left is the air temperature one left.
