DIAGNOSIS
Step 5
1) If the position sensor output voltage is 0.5 V and less at fully
close position, adjust the output voltage to specified by
turning out the
NO.1
cable adjuster
CD.
2) Repeat the above procedure (Step 4) until the out put voltage
becomes specified value. (If C46 code is indicated after
adjusting the voltage, increase the voltage to 0.4 V.)
ICAUTION I
* Adjusting the cable with the EXCV
fully
opened or
fully
closed can damage the EXCVA. Be sure to
adjust
the cable with the EXCV set in adjustment
position.
(CT6-4)
* Do

turn
the EXCVA pulley using the wrench.
3) If the position sensor output voltage is 4.5 V and more at fully
open position, adjust the output voltage to specified by
turning out the NO.2 cable adjuster
~.
Repeat the above procedure (Step 4) until the output voltage
is within the specified value.
