limp mode

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Ah, limp mode—the car's way of saying, "I'm done running at full speed, figure me out!" Since you've already swapped the throttle body and pedal switch on your 2010 Dodge Journey, the issue could be lurking elsewhere. Check for wiring issues or a bad sensor, especially the transmission input/output sensors or the PCM (powertrain control module). It could also be something as simple as a ground wire acting up. Random limp mode is like playing automotive whack-a-mole, but don't give up!
