Throttle Position (TP) Sensor On-Vehicle Inspection

  1. Warm up engine and stop it when its temperature has reached normal operating temperature (Make sure that they have some clearance between fast idle cam and cam follow lever.).
  2. Disconnect negative cable at battery and coupler from TP sensor.
  3. Using ohmmeter, check for resistance between terminals under each condition. If check result is not satisfactory, replace TP sensor.

    TP sensor resistance 

    Between "1" and "3" terminals: 4 - 6 kohm 

    Between "2" and "3" terminals: 0 - 4.6 kohm (varying linearly according to throttle valve opening)
