P1110 Throttle Actuator Control Module Performance

Component Location





General Description

The ETS(Electronic Throttle System) is the throttle body whose throttle angle is controlled by control module. It consists of ETS unit,ETS-motor, Accelerator Position Sensor(APS),Throttle Position Sensor(TPS) and Limp home valve. The PCM sends throttle valve target opening value to ETS unit after calculating from signals such as APS and other input values. The ETS unit controls ETS motor to meet PCM's throttle valve target opening value. TPS is mounted on throttle body assembly and detects the opening angle of the throttle valve. The TPS is a variable resistor(potentiometer) whose characteristic is that the resistance changes according to throttle position angle. TPS 1 and TPS 2 signals are used to monitor PCM's throttle valve target opening value's activation between PCM and ETS unit. TPS1's output signal is the main signal to calculate the target value for opening throttle valve and to decide whether TPS2 is normal or not. TPS2's output signal is the sub signal to decide whether TPS1 is normal or not. And if TPS1's signal is abnormal, TPS2's output signal is used as the main signal.
