Circuit Description
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The Engine Control Module (ECM) controls the throttle blades by applying a varying voltage to the throttle valve motor. The ECM monitors the actual throttle blade position using the Throttle Position (TP) sensor 1 and 2. If the ECM detects the throttle actuator control system does not operate in the desired throttle range, DTC P2107 sets.
