Default MAT sensor help.
I'm still trying to find why my car is running so rich. I want to check the MAT sensor, but the search isn't bringin' up an ohm table for it. Can someone help me with that?

If the mat sensor is telling the computer its super cold outside, maybe thats why I'm runnin' so rich. Just a thought, can be tested for free!

If you have a MAF the MAT has no effect on richness; if a SD system a bad MAT sensor could cause it to run rich.

oh, well, nevermind. Does the mat do anything for me then? I've seen something about egr before, but I don't have egr.

The MAT sensor is used for EGR control. I know of no other use for it.
