Q: Warning Lights "Red lightning bolt" on 2003 Dodge Ram 2500

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
doing 65 MPH with cruise control on. Suddenly the cruise control shut off and "check engine light came on"
and then a "red lightning bolt" started flashing". I got off the Interstate and read manual and then shut engine off and waited ten minutes and when I started engine the "check engine light" was still on, but the red lightning bolt was not flashing or even on. I turned around and came back home. I took Dodge to garage and parked it. They later started truck and no warning lights
were on. What is going on?????? Help!!!

I had a similar problem without the cruse on and the engine did not shut down. The engine light came on and the red lightening bolt warning turned on without flashing. I had access to a code reader the the result was P2175. This is a used pickup that I am looking to buy but probably will not now. I hope that this helps someone. The code reader also reported Throtal Actuator control system low air flow detector.
