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 "REFERENCE DATA "

    4. Is resistance within specifications?

      [REFERENCE DATA] 

      REFERENCE DATA

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

      YES 

      • Go to  2"CHECK PCM/TCM" as below.

      NO 

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

    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.
