Q: What does code P2119 mean?

Throttle Actuator Control Throttle Body Range/Performance. P2119 is a generic powertrain code indicating that the engine computer has detected a problem with the throttle actuator control (TAC) system's ability to maintain the commanded throttle plate position within the expected range. The computer compares the actual throttle position from the throttle position sensor (TPS) to the desired position and sets this code when the two do not match for a calibrated period, often during a self-test or while the throttle is being moved.
