ENGINE RPM FLUCTUATION - CRUISE CONTROL CABLE ADJUSTMENT PROCEDURE
This TSB has been revised to include additional diagnostic trouble codes and adaptation clearing instructions.
DESCRIPTION:
This bulletin provides diagnostic and service procedures for a vehicle that may experience engine RPM fluctuation and also exhibits some or all of the
following:
^
The vehicle has less than approximately 2,000 miles on the odometer or the vehicle has had the cruise control cable removed recently.
^
The TPS Adaptation Value (as displayed by the Hi-Scan Pro in the "Current Data" Menu) has reached its maximum value of 29.9%. A common
value is typically less than 10%.
^
The TPS Value (as displayed by the Hi-Scan Pro in the Current Data Menu) does not increase until the throttle pedal has been depressed about 25%
of its normal travel.
^
The vehicle may also have a higher than specified idle and DTC P0507 (Idle Speed Higher Than Expected) may also be found stored in the ECM.
^
The vehicle may also have less throttle response than expected.
^
The ECM may have diagnostic trouble codes P0121 (TPS Plausibility) and/or P0123 (TPS High Input) stored.
This TSB applies to the following models:
^
1999-2002 Sonata V6
^
2001-2002 Santa Fe V6
^
2001-2002 Elantra

POSSIBLE CAUSE:
The cause of the condition may be a cruise control cable that needs adjustment. A cruise control cable that needs adjustment may be positioning the
throttle plate slightly open, causing all or some of the symptoms mentioned above.
REPAIR PROCEDURE:
Correct the condition by creating a slight slack in the cruise control cable. Adjust the cable at either the throttle body end or the cruise control module
end (depending on the model).
