45 45 ETS(Electronic control Throttle valve) The throttle valve opening is control by throttle motor which is controlled by ETS control module. Accelerator position sensor detects the acceleration pedal position. It sends a signal to ETS control module and ECM. Throttle position sensor detects the throttle valve position. It also sends a signal to ETSCM and ECM. The throttle position sensor signal is used for feed back control. ETS system of Centennial is similar to XG ETS. The differences are - None failsafe motor - No initialization
