Kia Sedona (2008 year). Manual - 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.
