Throttle Position Sensor Test

  1. Turn ignition switch to "OFF" position. Disconnect sensor connector. Check resistance across poles "1" and "3". Total resistance should read 4000-6000 ohms.
  2. Connect a circuit tester across poles "1" and "2" or across poles "2" and "3". Check to ensure that when throttle valve is slowly operated from idle to fully opened position, resistance changes smoothly.
