MANY things can make your check engine light come on. Some of the common things are low coolant level, high coolant temp., low oil pressure, high oil temp., any bad sensor or bad wiring to the sensors and much more.

On your truck you should be able to find out a code that causes a check engine to come on. Turn your cruise control off and hold your cruise control SET button down and start counting. For example it will flash 9times then little pause and flash 2time. You got a code 92 that you can even look up online on google. com
