Code P2120 2006 Toyota Camry Description
In the accelerator pedal position sensor, the voltage applied to terminals VPA and VPA2 of the Engine Control Module (ECM) changes between 0 V and 5 V in proportion to the angle of the accelerator pedal. The VPA is a signal to indicate the actual accelerator pedal angle and is used for the engine control. VPA2 is used to detect malfunctions of the sensor itself.
The ECM monitors the accelerator pedal angle from VPA and VPA2 signal outputs, and controls the throttle motor based on these signals.
