This will allow the ECM to automatically learn the throttle valve position. If equipped with a push button start system, push the engine start button two times without depressing the brake pedal. In this case, repeat the above procedure.

If the engine is started without waiting for at least five seconds after turning the ignition to the on position to allow the ECM to automatically learn the throttle valve position, MIL illumination with DTC P0638 and P2110 will occur. Keep in mind your radio will go into SAFE mode so make sure you have the code to. This will drain any power left in the brain and should result in a full throttle body recalibration once everything is reconnected. Wait for five seconds after turning on the ignition. To do this disconnect the +/- battery leads and touch them together (you may need to use a wrench or something to bridge the gap). Select “Reset,” then wait 10 seconds after turning the ignition key off (Relay off).Ħ. RESET/RELEARN ETC ADAPTIVE VALUE SERVICE PROCEDUREĥ.

If starting the engine without resetting/relearning the ETC adaptive values, DTCs P0638(throttle actuator control range/performance) or P2110 (throttle actuator control system – force limited rpm) will be stored in the ECM memory and the MIL will illuminate. This bulletin provides the procedure to reset (erase) and relearn the Electronic Throttle Control (ETC) adaptive value (throttle valve position) on the following Kia vehicles: Rondo, Forte, Optima, Sorento and Sportage with Theta 2.0 or 2.4 gasoline engines with ETC systems.Īfter the repairs have been completed, the ETC adaptive value must be reset/relearned.
