Over last 18 months has intermittent problems with EPC light, traction control light and check engine light. Initially codes revealed problem in throttle body 2. Went to dealer 4 times on flat bed truck. 3 months ago changed the throttle body and PC relay. (cost $1600.00) 1 month ago problem re-surfaced. Took it to the local shop (Dons Service Center, Terre Haute, Indiana). electronics tech discovered and replaced the connector to the throttle body ($300.00). working OK so far.

Recommend electronics tech to trouble shoot these gremlins.
