Same problem here. 2013 journey 2.4l. Traction control light then limp mode. I replaced wheel sensors, no fix. Shop states etc motor performance and motor current codes. Told me it needed a new throttle body. Wanted to charge me 600. I pulled it out myself in under 15 mins. Awaiting new one to arrive. I have a feeling that this is not the problem. The old throttle body looks fine. Not dirty. Butterfly turning fine. No noise in it to make me believe one of the wheels inside is faulty. Guess we will see.
