7.
Loosen the VVEL control shaft position sensor mounting bolts
(1).
8.
Turn the VVEL control shaft position sensor (2) clockwise and
counterclockwise while monitoring the output voltage between
the VVEL control module terminals with a tester and adjust the
output voltage to be within the standard value.
9.
Tighten the VVEL control shaft position sensor mounting bolts.
10. Reconfirm that the output voltage of VVEL control shaft position sensor is within the standard value.
NOTE:
If it varies from the standard value after the mounting bolts are tightened, perform steps 7 to 9 again.
11. Turn ignition switch OFF and wait at least 10 seconds.
12. Start engine and warm it up to normal operating temperature.
13. Turn ignition switch OFF and wait at least 10 seconds.
14. Perform Idle Air Volume Learning. Refer to
EC-582, "IDLE AIR VOLUME LEARNING : Special Repair
.
