4. Is resistance within specifications?

YES



Go to "COMPONENT INSPECTION" procedure.

NO



Check for open in harness. Repair as necessary and Go to "VERIFICATION OF VEHICLE
REPAIR" procedure.



If ground circuit is OK, Go to step 2.

COMPONENT INSPECTION

1. Check "OUTPUT SPEED SENSOR"

1. Ignition "OFF".

2. Disconnect the "OUTPUT SPEED SENSOR" connector.

3. Measure resistance between terminal "1", "2" and "2", "3" and "1", "3" of the "OUTPUT SPEED

SENSOR" connector.

Specification: Refer to OUTPUT SPEED SENSOR SPECIFICATION CHART

5. Is "OUTPUT SPEED SENSOR" signal value changed according to simulation frequency?

YES



Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination,
deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF
VEHICLE REPAIR" procedure.

NO



Substitute with a known-good PCM/TCM and check for proper operation. If the problem is
corrected, replace PCM/TCM as necessary and then go to "VERIFICATION OF VEHICLE
REPAIR" procedure.

VERIFICATION OF VEHICLE REPAIR

Refer to DTC P0717.

GENERAL DESCRIPTION

The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the
1st gear ratio, while the transaxle is engaged in the 1st gear. For example, if the output speed is 1000 RPM and
the 1st gear ratio is 4.497, then the input speed is 4,497 RPM.

DTC DESCRIPTION

This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by
the 1st gear ratio, while the transaxle is engaged in 1st gear. This malfunction is mainly caused by mechanical
troubles such as control valve sticking or solenoid valve malfunctioning rather than an electrical issue.
