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 DATA REFERENCE CHART

    4. Is resistance within specifications?

      [REFERENCE DATA] 

      DATA REFERENCE CHART

      Data Reference Data
      Current 22 mA
      Air Gap Input sensor 1.3 mm
      Output sensor 0.85 mm
      Resistance Input sensor Above 4 MΩ
      Output sensor Above 4 4 MΩ
      Voltage High 4.8 ~ 5.2V
      Low Below 0.8V

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

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

  2. CHECK 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 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.
