Vehicles Without Auto-Cruise Control System

CLOSED THROTTLE POSITION SWITCH AND THROTTLE POSITION SENSOR ADJUSTMENT







1. Connect the scan tool to the data link connector. When not using the scan tool, proceed as follows.
1. Disconnect the connector of the throttle position sensor.
2. Connect an ohmmeter between terminal 3 (closed throttle position switch) and 4 (sensor ground) by using jumper wires.




2. Insert a feeler gauge with a thickness of 0.45 mm (0.177 in.) between the fixed SAS and the throttle lever.
3. When using the scan tool, turn the ignition switch ON. (Do not start engine.) Observe operation of the closed throttle position switch.




4. Loosen the throttle position sensor mounting bolt, then turn the throttle position sensor body fully counter clockwise.
5. In this condition, make sure that the closed throttle position switch is ON.
6. Slowly turn the throttle position sensor clockwise until the point at which the closed throttle position switch is turned OFF is found.
Tighten the throttle position sensor installation bolt at that position. Proceed to Step 8.




7. When not using the scan tool, proceed as follows:
1. Connect the special tool (test harness set) between the throttle position sensor connectors which have been disconnected. (Connect all terminals taking care not to mistake the terminal No.)
2. Connect a digital voltmeter between the throttle position sensor terminal 2 (sensor output) and terminal 4 (sensor ground.)
3. Turn the ignition switch ON (but do not start the engine).

8. Check the throttle position sensor output voltage.

Standard value: 400 - 1,000 mV

9. If there is a deviation from the standard value, check the throttle position sensor and the related harness.
10. Remove the feeler gauge.
11. Switch OFF the ignition switch.
