Accelerator pedal position sensor converts accelerator pedal angle into an electrical signal and delivers output signal to Hybrid Vehicle (HV) control Electronic Control Unit (ECU). Hybrid vehicle control ECU is referred to as HV ECU. The HV ECU communicates with the ECM for controlling the Electronic Throttle Control System (ETCS) for throttle operation. See ELECTRONIC THROTTLE CONTROL SYSTEM under AIR INDUCTION SYSTEMS for additional information.
