Accelerator Position Sensor

GENERAL DESCRIPTION
The ETSCM (Electronic Throttle System Control Module) is integrated with PCM (Powertrain Control Module). Therefore, Make sure that location of ETS Module is changed. The ETS (Electronic Throttle System) is the throttle body whose throttle angle is controlled by control module. It consists of ETS-motor, Accelerator Position Sensor (APS),Throttle Position Sensor (TPS) and Limp home valve. Among above-mentioned parts, APS consists of APS1, APS2 and idle switch which detects the closed throttle position. When a driver steps on the gas pedal, the output signal of APS1 is used for the sub signal and that of APS2 is used for the main signal. And if the PCM receives theses signals and other input values, it calculates throttle valve target opening value and then controls ETS motor to meet the throttle valve target opening value.
