    Just got this code. What does the Speed Sensor do and where can it be
    found on a 2002 Hyundai SantaFe 2.7 engine ? Many thanks.

    Did you retrieve this code from the Engine or Transmission computer?

    It was retrieved from the plug in access located in the Fuse Box by
    the Parking Brake Release .

    Is you speedometer working? I'm thinking its the vehicle speed sensor
    normally attached to one of the front wheels. Check to see if wiring loose
    or broken.

    I'm going to presume that this, along with the reply regarding the
    location of the connector where you checked for the code, imply that
    you've scanned the Engine Control Module with a generic scanner.

    The ECM receives vehicle speed information from the right front wheel
    speed sensor, presuming your Santa Fe isn't equipped with ABS. Check
    the tone wheel on the axle and check the wiring going to the sensor,
    especially for being chewed by rodentia. These are far more common
    problems than problems with the sensor itself.

    If you have ABS, the vehicle speed signal is received via a dedicated
    wire running from the ABS module to the ECM. If this is the case, and
    you haven't seen an illuminated ABS lamp, then check the integrity of
    this wire.

    I have the same issue (also due to rodent damage) on a 2005 Manual Transmission Elantra 4-dr GT model. That car's value is pretty low, so two questions:

    1) how do I trace the wire to see where a break is ? I think the wire runs from near the transmission to the front passenger wheel, correct ? Do I need a lift for that ? And yes, I do have ABS lights lit p on the dash...

    And 2) if I have someone else address this, how much $$ am I wasting on it ? I need to pass emissions by Oct 31st and of course the CheckEngine light comes on and off (mainly off) while the problem exists. Thanks !

    The vehicle uses two speed sensors.
    One is in the front right wheel. It checks the speed of the wheel
    The other is in the transmission.
    It checks the gear speed of the transmission and relates it to the average speed of the vehicle
    The ECU compares the two to determine if the vehicle is correct
    If not the ECU can put the vehicle in limp mode.

    If the ABS light is on and off then would assume it is the front right ABS sensor.

    Thank you so much!!! So in your opinion, is it cost effective to pursue this on an '05 with about 125K miles on it ? Dang desert rats, here in AZ, cause lots of damages to several of us ….Cheers !
