Thanks everyone. After reading these posts I decided to go back and re check some things. Started with checking the Fuses for the Fan control 1 and the Fan Control 2-3. They are 25 amp. Used my Volt Meter to check each side of the fuse and found the fuse for Fan Control 2-3 was blown on one side. It shows 12 on one side and nothing on the other. Changed that fuse. Took the car out ran some errands and no Check Engine light so far. This is the longest I have gone without the Check Engine light coming on.
I’m hoping this solves the problem.
Still wondering why that fuse would have gone. And if it goes bad again where would I look to find what is causing it.
