HFT
DTC 25-1 (SW ASH PLATE ANGLE
SENSOR LOW VOLTAGE)
• Before starting inspection, Check for loose or
poor connectors on the swash plate angle sensor
3P connector and TCM 33P (Black) connector,
then check the DTC.
• When removing the swash plate angle sensor,
Perform the HFT initialization procedure (page 11-
93).
1. Swash
Inspection
Remove the swash plate angle sensor (page 11-
100
Measure the resistance at the swash plate angle
sensor A and C terminals of the sensor side.
CONNECTION: A - C
Is there resistance w ith in 1.6 - 2.4 ki2 (20°C7
68 F)?
YES
NO
2. Swash
Inspection
Inspect the resistance of the swash plate angle
sensor shaft groove turning.
CONNECTION: A - B
Is there resistance w ith in 0 to 1 .6 -2 .4 k & (20 °C/
68 F)?
YES
NO
3. Swash
Inspection
Turn the ignition switch ON and engine stop
switch " O " .
Measure the voltage between the swash plate
angle sensor connector and ground.
CONNECTION: Black/blue (+) - Ground (-)
Is the voltage w ith in 4.75 - 5.25 V?
YES
NO
