Before you erase the error codes on your Kia Sportage, the problems must be addressed. The error codes are sent by the on-board engine management computer when an irregularity is recognised. This error code could be either a sensor or an electromechanical object used for engine management. To clarify, electromechanical objects create mechanical motion through the introduction of an electrical current, such as an idle air controller, EGR purge solenoids or fuel injectors. The error codes denoted by the check engine light in no way reflect engine mechanical problems. The check engine light only tracks the items that it operates.

  1. 1

    Insert the code scanner cable connector into the OBD (on-board diagnostics) port located on the driver's side under the dash just to the left of the steering column. Turn the ignition switch to the "Run" position but do not start the engine.

  2. 2

    Depress the "Erase" key on the face of the code scanner to delete the code from the computer's memory. This will reset the computer and turn off the check engine light until the next recognised irregularity in the computer system.

  3. 3

    Start the engine and drive the SUV for five miles. Shut the engine off. Reconnect the scanner and turn the key to the "Run" position.

  4. 4

    Depress the "Read" key on the scanner. If the repair was done properly, the scanner should respond with a "No Codes Stored" statement on the display. Turn the key off and disconnect the scanner.

Tips and warnings

  • A code scanner is the only way to interface with the on-board computer and extract the codes. Code scanners can be purchased at any auto parts store and are not expensive. They are also compatible on all vehicles.
