4-88 FI SYSTEM 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 turn-
ing out the No. 1 cable adjuster 1.
2) Repeat the above procedure (Step 4) until the out put voltage
becomes specified value. (If C46/P1657 code is indicated
after adjusting the voltage, increase the voltage to 0.4 V.)
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 2.
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 Output Voltage 1.3
EXCV is fully open : 3.7 Output Voltage 4.5
Is the voltage OK?
3) After repairing the trouble, clear the DTC using SDS tool.
(4-27)
* 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. (6-4)
* Do not turn the EXCVA pulley using the wrench.
YES
Replace the ECM with a known good one, and
inspect it again.
NO Replace the EXCVA with a new one.
