Throttle Position Sensor: MR2

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tacoma, 2002 Toyota RAV4, 2002 Toyota Prius, 2002 Toyota MR2, and 2002 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.

There are 2 types of throttle bodies and Throttle Position (TP) sensors, depending on type of transaxle used. On models with standard type manual transaxle, the driver operates the clutch and shifts the transaxle. On models with sequential manual transaxle, transaxle is electronically controlled and clutch is operated and transaxle is shifted hydraulically by moving shift lever forward or backward. Sequential manual transaxle may be identified by shift lever pattern which consists of "R", "N", "S" and "+" in place of conventional type shift lever pattern and no clutch pedal is used. On this model, a different type TP sensor is used. On all models, manufacturer does not list procedure for TP sensor adjustment. Only information available is for checking resistance of TP sensor.
On models with sequential manual transaxle, it may be necessary to remove throttle body for access to electrical connector at TP sensor. If necessary to remove throttle body, see THROTTLE BODY under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article. On all models, disconnect electrical connector from TP sensor. Note electrical terminals on TP sensor. See Figure and Figure .
On models with standard type manual transaxle, using ohmmeter, check resistance between specified terminals in relation to throttle position. See THROTTLE POSITION SENSOR RESISTANCE table. Replace components as necessary if resistance is not within specification.
On models with sequential manual transaxle, using ohmmeter, check resistance between VC and E2 terminals on TP sensor. Replace components as necessary if resistance is not within specification. See THROTTLE POSITION SENSOR RESISTANCE table.
