Operation



Specific to:

Hyundai Santa Fe 2006-2008

Hyundai Veracruz 2007-2008

The sensor is a Hall-effect sensor. The sensor converts the transaxle gear revolutions into pulse signals, which are sent to the PCM.

Removal & Installation



Specific to:

Hyundai Santa Fe 2006-2008

Hyundai Veracruz 2007-2008

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Raise and support the vehicle safely.
  4.  
  5. Place a drip pan below the Vehicle Speed Sensor (VSS) to catch any spilled fluid when it is removed.
  6.  
  7. Disconnect the VSS connector.
  8.  
  9. Remove the sensor from its mounting.
  10.  

To install:

  1. Installation is the reverse of the removal procedure.
  2.  
  3. Replace any lost transaxle fluid.
  4.  

Testing



Specific to:

Hyundai Santa Fe 2006-2008

Hyundai Veracruz 2007-2008

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Many malfunctions in the electrical system are caused by poor harness and terminal connections. Faults can also be caused by interference from other electrical systems and mechanical or chemical damage.
  4.  
  5. Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, or damage.
  6.  
  7. Make repairs as necessary.
  8.  
  9. Turn the ignition OFF .
  10.  
  11. Disconnect the VSS connector.
  12.  
  13. Start the engine.
  14.  
  15. Measure the voltage between terminal 1 of the VSS harness connector and a chassis ground. Specification: Battery voltage (approximately 12 volts).
    1. If the measured voltage is within specifications, inspect the ground circuit.
    2.  
    3. If the measured voltage is not within specifications, check for an open/short to ground in the power harness.
    4.  

  16.  
  17. Repair as necessary.

  18.  
  19. Inspect the ground circuit.
    1. Turn the ignition "OFF."
    2.  
    3. Disconnect VSS connector.
    4.  
    5. Measure the resistance between terminal 2 of the VSS harness connector and the chassis ground. The specification: Approx. 0 ohms.
    6.  
    7. If the measured resistance is within specifications, inspect the signal circuit inspection.
    8.  
    9. If the measured resistance is not within specifications, check for an open/short to power in the ground harness. Repair as necessary.
    10.  

  20.  
  21. Inspect the signal circuit
    1. Turn the ignition "OFF."
    2.  
    3. Connect a scan tool to the Data Link Connector (DLC).
    4.  
    5. Start the engine and select "SCOPEMETER FUNCTION" on the scan tool.
    6.  
    7. Drive the vehicle and measure the output signal between terminal 3 of the EPS CM harness connector and chassis ground. Specification: see waveform illustration.

    8.  
    9. If the VSS output signal is within specifications, substitute with a known-good EPS CM and check for proper operation.
    10.  
    11. If the problem is corrected, replace the EPS CM.
    12.  
    13. If the VSS output signal is not within specifications, check for an open/short to ground in the signal circuit and other systems which use the VSS. Repair as necessary.
    14.  
    15. If the VSS is found faulty, replace with a new component.
