How does this effect the air and fuel systems?
Expert:  Tim's Auto Repair replied 4 months ago.

the ect tells the computer if the engine is cold or hot..when cold the computer will inject way more fuel than it does when hot.[like a choke on a carb]when warm,the computer doesnt give nowhere as much fuel..it uses this ect to sense the temperature to determine how much fuel to give it.
