Thanks for the definition to malfunction-that helped a lot. basically what I'm wondering, would the sensor set off the other code?-Transmission Control System Malfunction. I can figure out the "basics" of what it means by deductive reasoning, I'm just wondering if one is linked to the other & if by replacing the sensor, would that most likely fix my problem? Also, should I go to the Jeep dealer for the part or pick one up at autozone, napa, ect.? Where is the sensor located? Thanks
