of sensor with your fingers.
• Do not damage the movable drive face posi-
tion sensor.
Is there resistance within 0 – 6.0 k

F)?
YES – GO TO STEP 5.
NO – Faulty movable drive face position sen-
sor
5. Movable Drive Face Position Sensor Power
Input Voltage Line Inspection
Turn the ignition switch ON and engine stop
switch " ".
Measure the voltage at the movable drive face
position sensor 3P connector of the wire side.
Is the voltage within 4.75 – 5.25 V?
YES – GO TO STEP 6.
