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.
  1. Idle speed is controlled by Engine Control Module (ECM) and is not adjustable. Check idle speed with engine at normal operating temperature, transaxle in Neutral, parking brake applied, air cleaner and all air intake hoses installed, all vacuum hoses installed, electronic fuel injection system wiring connectors properly installed, ignition timing properly set, electric cooling fan off, and A/C and all accessories off.
  2. Start engine and warm engine to normal operating temperature. Shut engine off. Connect Toyota hand-held tester to data link connector No. 3 at driver's side of instrument panel. See Figure. Hand-held tester is used to read engine RPM.
  3. Apply parking brake. Place transaxle in Neutral. Start engine and increase engine speed to 2500 RPM for 90 seconds and then allow engine to idle while reading idle speed from CURRENT DATA on hand-held tester. Ensure idle speed is within specification. See IDLE SPEED SPECIFICATIONS  table. Shut engine off. Remove hand-held tester.
  4. If idle speed is not within specification, check air intake system. If air intake system is okay, check throttle body. See IDLE CONTROL SYSTEMS in SYSTEM & COMPONENT TESTING - 4-CYLINDER article.
