13 ADJUSTMENT THROTTLE POSITION SWITCH CLOSED POSITION-II
With CONSULT-II
1. Temporarily tighten sensor body fixing bolts as follows.
+Gradually move the sensor body clockwise and stop it when ªCLSD THL/P SWº signal switches from ªOFFº to
ªONº, then temporarily tighten sensor body fixing bolts.

2. Make sure two or three times that the signal is ªONº when the throttle valve is closed and ªOFFº when it is opened.
3. Remove 0.05 mm (0.0020 in) feeler gauge then insert 0.15 mm (0.0059 in) feeler gauge.
4. Make sure two or three times that the signal remains ªOFFº when the throttle valve is closed.
5. Tighten throttle position sensor.
6. Check the ªCLSD THL/P SWº signal again.

14 RESET THROTTLE POSITION SENSOR IDLE POSITION MEMORY
With CONSULT-II
NOTE:
Always warm up engine to normal operating temperature. If engine is cool, the throttle position sensor idle posi-
tion memory will not be reset correctly.
1. Confirm that proper vacuum is applied. Refer to Test No. 10.
2. Attach blind cap to vacuum port from which vacuum hose to throttle opener was disconnected.
3. Start engine.
4. Warm up engine to normal operating temperature.
5. Select ªTP SW/TP SEN IDLE POSI ADJº in ªWORK SUPPORTº mode.
6. Stop engine. (Turn ignition switch ªOFFº.)
7. Turn ignition switch ªONº and wait at least 5 seconds.
