Avalon, Camry Solara, Sienna, Tacoma & Tundra

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2003 Toyota Tundra, 2003 Toyota Tacoma, 2003 Toyota Sienna, 2003 Toyota Sequoia, and 2003 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
  1. Manufacturer does not list procedure for Throttle Position (TP) sensor adjustment. Only information available is for checking resistance of TP sensor.
  2. Disconnect electrical connector from TP sensor. Note electrical terminals on TP sensor. See Fig 1-Fig 4 . Apply vacuum to throttle opener.
  3. 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.
