Ok I was driving home from work today and the Check Engin light came on
I took it to Auto Zone and had them hook up the truck and the guy said the only code comming up was a Coolent Temp. Sens. he erased the code. I know the other day when it was like -15 out it took forever to warm up but the truck is running fime and Temp Gage is good reading were is should. anyone else had this problem? should I run the truck and see if the code comes back or go ahead and change the sensor?
