Component Inspection

WARNING: This page is about a different car, the 2007 Kia Optima, 2007 Kia Magentis, 2006 Kia Optima, and 2006 Kia Magentis. However, it is still accessible from the selected car via links, so may be relevant.

Check "OUTPUT SPEED SENSOR"

Ignition "OFF".
Disconnect the "OUTPUT SPEED SENSOR" connector.
Measure resistance between terminal "1","2" and "2","3" and "1","3" of the "OUTPUT SPEED SENSOR" connector.
Specification: Refer to DATA REFERENCE CHART

YES : --> Go to 2 "CHECK TCM (PCM)" as below.

no : --> Replace "OUTPUT SPEED SENSOR" as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

CHECK TCM (PCM)
1. Ignition "ON" & Engine "OFF".
2. Connect "OUTPUT SPEED SENSOR" connector.
3. Install scantool and select a SIMU-SCAN.
4. Simulate frequency to OUTPUT SPEED SENSOR signal circuit.

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 TCM (PCM) and check for proper operation. If the problem is corrected, replace TCM (PCM) as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
