P2120 APP SENSOR
DescriptionINFOID:0000000001162667
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensors detect the accelera-
tor pedal position and sends a signal to the ECM. The ECM uses the
signal to determine the amount of fuel to be injected.
