Kia Sedona (2008 year). Instruction — part 96

GROUND CIRCUIT INSPECTION

1. Ignition "ON" & Engine "OFF".

2. Disconnect the "INPUT SPEED SENSOR" connector.

3. Measure resistance between terminal "1" of the INPUT SPEED SENSOR harness connector and chassis

ground.

Specification: approx. 0 ohms

4. Is resistance within specification?

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 in harness is OK, Go to step 2.

COMPONENT INSPECTION

1. Check "INPUT SPEED SENSOR"

1. Ignition "OFF".

2. Disconnect the "INPUT SPEED SENSOR" connector.

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

SENSOR" connector.

Specification: Refer to RESISTANCE SPECIFICATION CHART

5. Is "INPUT 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

After a repair, it is essential to verify that the fault has been corrected.

1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode.

2. Using a scan tool, Clear DTC.

3. Operate the vehicle within DTC Enable conditions in General information.

4. Is resistance within specification?

YES



Go to the applicable troubleshooting procedure.

DTC P0722 OUTPUT SPEED SENSOR CIRCUIT - NO SIGNAL

COMPONENT LOCATION

Refer to DTC P0717.

GENERAL DESCRIPTION

The Output Speed Sensor outputs pulse-signals according to the revolutions of the output shaft of the
transmission. The Output Speed Sensor is installed in front of the Transfer Drive Gear to determine the Transfer
Drive Gear RPMs by counting the frequency of the pulses. This value, together with the throttle position data, is
mainly used to decide the optimum gear position.

DTC DESCRIPTION

The TCM sets this code if the calculated value of the pulse-signal is noticeably different from the value
calculated, using the Vehicle Speed Sensor output, when the vehicle is running faster than 30 km/h. The TCM
will initiate the fail safe function if this code is detected.
