temperature/ cold start problems

[sphinx0nine]

after putting about 100 miles on the car today i realized that the car runs really cold, and the check engine light came on as i was comming down the mountain. it seems like the faster i go the cooler the car runs. I connected the car to the laptop and it told me that the problem was the coolant temp. sensor. Is this the sensor that's on the bottom part of the radiator?


Theres should be a valve that helps the car start when its really cold. wich one is it? because i dont think mine is workin, it took me about 5 min. to turn the car on this morning. any ideas?

The coolant temp sensor is on the thermostat housing, not the bottom of the radiator. I think the other part you are referring to is the fast idle air valve. It's located on the throttle body.
