My check engine light is on. I ran the obdII on it and the code was INTAKE AIR HEATER CIRCUIT A MALFUNCTION. What would cause that problem. The only thing I can think is the IAT sensor. I haven't done anything performance wise to the truck other than a k&n air filter. Any experienced help would be great.
