TSB: VOLUNTARY SERVICE CAMPAIGN: ECM UPGRADE - MIL ON WITH DTC P0087 (SC114) - THIS BULLETIN PROVIDES INFORMATION RELATED TO AN ECM SOFTWARE UPDATE FOR THE ENGINE CONTROL UNIT (ECU) IN CERTAIN 2012~2014MY SORENTO, 2012~2013MY OPTIMA, AND 2012~2013MY SPORTAGE VEHICLES EQUIPPED WITH THE 2.4L AND 2.0L TURBO GDI ENGINES. THE SUBJECT VEHICLE’S ENGINES ARE EQUIPPED WITH A GASOLINE DIRECT INJECTION (GDI) SYSTEM THAT UTILIZES A FLOW CONTROL VALVE (FCV) TO CONTROL THE SUPPLY OF FUEL. THE FCV NEEDLE MAY EXPERIENCE EXCESSIVE WEAR, EVENTUALLY RESULTING IN IMPAIRMENT OF FUEL FLOW. IF THAT HAPPENS, AND TO PROTECT THE ENGINE, THE ECU MAY REDUCE ENGINE ACCELERATION WHILE ILLUMINATING THE “CHECK ENGINE” OR MALFUNCTION INDICATOR LAMP (MIL). THE ECU UPDATE WILL IMPROVE THE DURABILITY AND OPERATION OF THE FCV NEEDLE.
