11 CHECK THROTTLE POSITION SWITCH CLOSED POSITION-II
With CONSULT-II
1. Connect ªCONSULT-IIº to the data link connector and select ªENGINEº from the menu. Refer to EC-83.
2. Turn ignition switch ªONº.
3. Select ªTP SW/TP SEN IDLE POSI ADJº in ªWORK SUPPORTº mode with CONSULT-II.
4. Read ªCLSD THL/P SWº signal under the following conditions.
+Insert a 0.05 mm (0.0020 in) and 0.15 mm (0.0059 in) feeler gauge alternately between stopper and throttle drum as
shown in the figure and check the signal.

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.
