Throttle Control Motor (MR2 With Sequential Manual Transaxle)
There are 2 types of manual transaxles used for this model. Standard type manual transaxle in which the driver operates the clutch and shifts the transaxle, and the sequential manual transaxle, which is electronically controlled and the clutch is operated and transaxle is shifted hydraulically by moving the shift lever forward or backward. Sequential manual transaxle may be identified by the shift lever pattern which consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and there is no clutch pedal. Models with sequential manual transaxle use throttle control motor with Electronic Throttle Control System (ETCS) for controlling throttle operation and idle speed. See ELECTRONIC THROTTLE CONTROL SYSTEM under AIR INDUCTION SYSTEMS for additional information.
