Adjusting TP Sensor

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Lexus SC 430, 2002 Lexus RX 300, 2002 Lexus LX 470, 2002 Lexus LS 430, and 2002 Lexus IS 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Data link connectors No. 1 or 3 may also be referred to as DLC1 or DLC3.
  1. Loosen 2 sensor mounting screws. Turn TP sensor until it no longer contacts throttle valve shaft. Turn TP sensor back until it just starts to touch throttle valve shaft, then snug mounting screws. On GS300, IS300 and LX470, disconnect accelerator pedal position sensor connector. On all models, connect scan tool to DLC3. See Figure. Go to next step.
  2. Turn ignition switch on. DO NOT depress accelerator pedal. On scan tool, select CURRENT DATA, then THROTTLE POS. Slowly turn TP sensor until value is as specified. See TP SENSOR SPECIFICATIONS  table. Tighten sensor mounting screws. Go to next step.
