4-98 FI SYSTEM DIAGNOSIS
Step 5
1) If the EXCVA position sensor output voltage is 0.5 V and less
at EXCV fully closed position, adjust the output voltage to the
specified value by turning out the No.1 cable adjuster
2) Repeat the above procedure (Step 4) until the output voltage
becomes specified value. (If C46/P1657 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
position. ( 6-4)
* Do not turn the EXCVA pulley using the wrench.
3) If the EXCVA position sensor output voltage is 4.5 V and
more at EXCV fully opened position, adjust the output voltage
to the specified value by turning out the No.2 cable adjuster
.
Repeat the above procedure (Step 4) until the output voltage
is within the specified value.
EXCVA position sensor output voltage
EXCV is fully closed : 0.5
EXCV is fully opened: 3.7
Is the voltage OK?
Replace the ECM with a known good one, and
YES
inspect it again.
NO Replace the EXCVA with a new one.
4) After repairing the trouble, clear the DTC using SDS tool.
