Throttle Position Sensor (TPS)

  1. The use of Diagnostic Tester (M.S. 1700) is preferred when adjusting the TPS.
  2. If digital voltmeter is used, disconnect Idle Speed Control (ISC) motor electrical connector. Connect ISC Tester (AB.99) and Harness Adapter (Ele.CT.02). Retract ISC plunger until throttle lever contacts the idle stop screw and plunger does not contact the throttle lever.
  3. Turn ignition on. Insert negative lead of voltmeter in terminal "D" and positive lead to terminal "A" of TPS. Voltmeter reading should be 5 volts. Insert voltmeter positive lead to terminal B", reading should be 4.65 volts.
  4. To adjust, loosen TPS retaining screws and pivot sensor to obtain correct reading.
