- Steering wheel is in the straight-ahead position, etc.

G THROTTLE POSITION SENSOR IDLE POSITION ADJUSTMENT

NOTE:
- Never adjust throttle adjust screw (TAS).
- Do not touch throttle drum when checking "CLSD THL/P SW" signal or "continuity", doing so may cause an incorrect adjustment.





1. Warm engine up to normal operating temperature.
2. Check FI cam. Refer to procedure C.
3. Stop engine.

NOTE: If handy vacuum pump is a already set, go to step 7.





4. Remove the vacuum hose connected to the throttle opener.
5. Connect suitable vacuum hose to the vacuum pump and the throttle opener.
6. Apply vacuum [more than -40.0 kPa (-300 mmHg, -11.81 inHg)] until the throttle drum become free from the rod of the throttle opener. During the TPS adjustment the vacuum should be applied.
7. Loosen throttle position sensor fixing bolts.











With Consult
8. Turn ignition switch "ON".
9. Select "DATA MONITOR" mode with CONSULT.
10. Select "CLSD THL/P SW" from the menu.
11. Read "CLSD THL/P SW" signal under the following conditions.
- Insert 0.2 mm (0.008 in) feeler gauge between throttle adjust screw and throttle drum and check the following.
- Open throttle valve and then close.
- "CLSD THL/P SW" signal should remain "OFF" when the throttle valve is closed. (If signal is "ON", turn throttle position sensor body counterclockwise until the signal switches to "OFF".)

12. Temporarily tighten sensor body fixing bolts as follows.
- Gradually move the sensor body clockwise and stop it when "CLSD THL/P SW" signal switches from "OFF" to "ON", then tighten sensor body fixing bolts.

13. Make sure the signal is "ON" when the throttle valve is closed and "OFF" when it is opened. Repeat it 2 or 3 times.
14. Remove 0.2 mm (0.008 in) feeler gauge then insert 0.3 mm (0.012 in) feeler gauge and check the following. Make sure the signal remains "OFF" when the throttle valve is closed. Repeat it 2 or 3 times.
15. Tighten throttle position sensor.
Check that the "CLOSED THL/P SW" signal remains "OFF" while closing throttle valve. If NG, repeat from the step 4.
After this adjustment, go to procedure H RESET THROTTLE POSITION SENSOR IDLE POSITION MEMORY.

Without Consult
8. Disconnect closed throttle position sensor harness connector.
9. Connect tester prove to the closed throttle position switch terminals 6 and 8 and check continuity under the following conditions.
- Insert the 0.2 mm (0.008 in) feeler gauge between the throttle adjust screw and throttle drum and check the following.
- Open throttle valve then close.
- The continuity should not exist while closing the throttle valve. If the continuity exists, turn throttle position sensor body counterclockwise until the continuity does not exist.

10. Temporarily tighten sensor body fixing bolts as follows.
- Gradually move the sensor body clockwise and stop it when the continuity comes to exist, then tighten sensor body fixing bolts.

11. Make sure the continuity exists when the throttle valve is closed and continuity does not exist when it is opened. Repeat it 2 or 3 times.
12. Remove 0.2 mm (0.008 in) feeler gauge then insert 0.3 mm (0.012 in) feeler gauge and check the following. Make sure the continuity does not exist when the throttle valve is closed. Repeat it 2 or 3 times.
13. Tighten throttle position sensor. Check that the continuity does not exist while closing the throttle valve. If NG, repeat from the step 5. After this adjustment, go to procedure II' RESET THROTTLE POSITION SENSOR IDLE POSITION MEMORY.
