I bought a Jetta car rental in 2008, and the Epc light came on, and the computer detected that the wiring harness was broken. After replacing the wire harness, the Epc light went out, but new problems appeared. ... I'm sorry to tell you that you were fooled by the master of the repair shop. . EPC light is on. Check whether the circuit on the throttle is connected to the circuit on the instrument panel. This is a short circuit. Solution: 1 If all lines are connected and there is no short circuit, replace the throttle sensor. 2. If the line is short-circuited, just connect the line. There is no need to change the harness. There is a lot of money. .

According to what you said, there should be something wrong with the throttle sensor. Replacing the throttle sensor can solve the problem.

Just my point of view.
