Answer 1

Hi there

This code is for the throttle actuator motor on the electronic throttle body. There is a factory service bulletin for a reflash on the computer that might solve the issue for you. The labor charge for this is .4 hours. Otherwise you might need a new throttle body. It has to be tested to give you an accurate estimate for the repair.
