1989 Cadillac DeVille 4.5L MIL Lamp on
Posted to GM Driveability on 12/22/1998

I pulled a code E38, MAT sensor open, but cannot find the sensor. Where is the MAT sensor located? I've tried all the usual places.

Customer reports no problems except SES light ocassionally comes on.

Thanks in advance.
