Re: ?sensors? need help

TPS = Throttle Position Sensor - tells computer how far you have your foot in it http://en.wikipedia.org/wiki/Throttle_position_sensor

IAC = controls airflow into the air/fuel mixture http://www.2carpros.com/articles/how...ol-valve-works

It's amazing what info is on the net, and how easy it is to find it with Google, Yahoo!, etc.
