FI SYSTEM DIAGNOSIS 4-97
Step 4
1) Turn the ignition switch OFF.
2) Connect the position sensor coupler
.
3) Measure the EXCVA position sensor output voltage at EXCV
fully closed position and fully opened position.
4) Insert the needle pointed probes to the back side of the
EXCVA position sensor coupler. ( Y – B/Br)
5) Disconnect the EXCVA motor coupler .
6) To set the EXCV to fully closed position, apply 12 V to and
terminals.
Positive wire – (P wire) terminal
Negative wire – (Gr wire) terminal
7) Turn the ignition switch ON.
8) Measure the EXCVA position sensor output voltage at EXCV
fully closed position.
9) Then, to set the EXCV to fully opened position, apply 12 V to
and terminals.
Positive wire – (Gr wire) terminal
Negative wire – (P wire) terminal
10)Measure the EXCVA position sensor output voltage at EXCV
fully opened position.
EXCVA position sensor output voltage
EXCV is fully closed: 0.5 – 1.3 V
EXCV is fully opened: 3.7 – 4.5 V
( Y – W)

Tester knob indication: Voltage ( )
Is the voltage OK?
11)After repairing the trouble, clear the DTC using SDS tool.
( 4-28)
YES
Replace the ECM with a known good one, and
inspect it again.
