Inspection (2.5L)

  1. Disconnect TP sensor connector. Connect ohmmeter between TP sensor connector terminals "E" and IDL. See Figure . Insert feeler gauge of specified thickness between throttle lever and throttle stop screw. See TP SENSOR CONTINUITY (2.5L) table.
  2. If continuity is not as specified, adjust TP sensor. See ADJUSTMENT procedure. If continuity is as specified, connect ohmmeter between TP sensor connector terminals Vt and "E". If resistance is less than 1000 ohms with throttle fully closed and about 5000 ohms with throttle wide open, TP sensor is adjusted. If resistance is not as specified, adjust TP sensor. See ADJUSTMENT procedure.
NOTE: If ohmmeter reading indicates a rough transition anywhere in range between lowest and highest readings, TP sensor potentiometer is faulty. Replace TP sensor.
