FI SYSTEM DIAGNOSIS
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
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.)
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
Do not 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.
Position sensor output voltage
EXCV is fully close: 0.5
EXCV is fully open: 3.7
Is the voltage OK?
Replace the ECM with a new one
Replace the EXCVA with a new one.
