ETCS consists of throttle body, accelerator pedal position sensor, Throttle Position (TP) sensor, throttle control motor, magnetic clutch and Engine Control Module (ECM). ETCS uses the ECM to calculate throttle valve opening in the throttle body in relation to driving conditions. ETCS controls operation of idle speed control system, cruise control system, traction control system (if equipped) and vehicle skid control system (if equipped). Accelerator pedal position sensor is mounted on throttle body and is integrated with throttle lever which attaches to the throttle cable. See Fig. 5 . Accelerator pedal position sensor consists of 2 sensors which delivers input signals to the ECM. TP sensor delivers input signals to ECM to indicate throttle valve opening.
ECM uses these input signals to operate throttle control motor to obtain proper operating speeds in relation to accelerator pedal position and engine speed, obtain proper idle speed, and operate cruise control system, traction control system (if equipped) and vehicle skid control system (if equipped). Throttle control motor is mounted on side of throttle body and operates throttle valve on throttle body by use of a magnetic clutch.
In the event of an ETCS malfunction, Malfunction Indicator Light (MIL) will be illuminated and Diagnostic Trouble Code (DTC) will be stored in ECM. MIL is displayed as an engine icon on instrument cluster on instrument panel. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM in appropriate SELF-DIAGNOSTICS article for retrieval of DTCs. If malfunction exists, magnetic clutch will be disengaged, allowing spring pressure to close the throttle valve. When magnetic clutch is disengaged, throttle control motor will not operate the throttle valve. If ETCS is shut off, accelerator pedal may be used to operate throttle valve for vehicle operation in limp mode by using limp mode lever on throttle body. See Fig. 5 .

2001 MR2 With Sequential Manual Transaxle & 4Runner
NOTE: On MR2 models, there are 2 types of manual transaxles used. The standard type manual transaxle in which the driver operates the clutch and shifts the transaxle, and the sequential manual transaxle, which is electronically controlled. The clutch is operated and transaxle is shifted hydraulically by moving the shift lever forward or backward. The sequential manual transaxle may be identified by the shift lever pattern and shift lever pattern consists of 'R', 'N', 'S' and '+' in place of the conventional type shift lever pattern and there is no clutch pedal.
On all models, ETCS consists of throttle body, accelerator pedal position sensor, Throttle Position (TP) sensor, throttle control motor, magnetic clutch and Engine Control Module (ECM). ETCS uses the ECM to calculate throttle valve opening in the throttle body in relation to driving conditions. ETCS controls idle speed and cruise control system operation. Accelerator pedal position sensor is mounted on throttle body and is integrated with throttle lever, which attaches to the throttle cable. See Fig. 6 and Fig. 7 . Accelerator pedal position sensor consists of 2 sensors which deliver input signals to the ECM. TP sensor delivers input signals to ECM to indicate throttle valve opening.
ECM uses these input signals to operate throttle control motor to obtain proper operating speeds in relation to

ETCS consists of throttle body, accelerator pedal position sensor, Throttle Position (TP) sensor, throttle control motor, Hybrid Vehicle (HV) control Electronic Control Unit (ECU) and Engine Control Module (ECM). Hybrid vehicle control ECU is referred to as HV ECU. ETCS uses the ECM to calculate throttle valve opening in the throttle body in relation to driving conditions. ETCS controls idle speed and cruise control system operation. Accelerator pedal position sensor is mounted near accelerator pedal. See Fig. 8 . Accelerator pedal position sensor consists of 2 internal sensors which deliver accelerator pedal position signals to the HV ECU. HV ECU in turn delivers the input signals to ECM. TP sensor delivers input signals to ECM to indicate throttle valve opening.
ECM uses input signals to operate throttle control motor to obtain proper idle speed and provide cruise control operation. Throttle control motor is mounted on side of throttle body and operates throttle valve. See Fig. 8 .
In the event of an ETCS malfunction, MIL will be illuminated and a DTC will be stored in ECM. MIL is displayed as an engine icon on instrument cluster at center of instrument panel. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM in appropriate SELF-DIAGNOSTICS article for retrieval of DTCs. If malfunction exists, voltage to throttle control motor is turned off in which throttle control motor becomes inoperative, allowing spring pressure to close the throttle valve.
