Re: I have a 02 GMC Envoy w/4.2L. OBDII reader says...
It's referring to a problem detected in throttle actuator control module, but if your not experiencing any driveability issues, it may have been set by a low battery condition as well. Are you experiencing any, or has battery gone low that you know of recently?
