DTC P2299 BRAKE PEDAL POSITION / ACCELERATOR PEDAL POSITION
Brake switch monitors malfunction of accel pedal sensor(APS).Drivers depress brake pedal when 1).the voltage higher
than driver’s intension is detected due to APS malfunction(signal circuit short to high voltage) 2).engine power generates
excessively due to fault signal.Like previous example, if driver’s intension to decelerate is transmitted to ECM(brake pedal
depressed) when APS signal is high, ECM consider APS to be fault and Limp Home mode is activated.When Limp Home
mode is activated, engine speed is fixed at 1200RPM and driving performance is limited, later, if correct APS signal is
detected, Limp Home mode is deactivated immediately.
P2299 is set when brake signal is inputted to ECM for more than 0.5 sec. while APS is depressed more than 5% at
above 870RPM, 2Km/h. And Limp Home mode is activated with the DTC code occurence. Later, if correct APS signal is
detected, Limp Home mode is deactivated immediately. This code is set when APS signal is a bit higher than the voltage
at accelerator released position and driver’s pedal manipulation, therfore careful inspection of APS and checking driver’s
pedal depressing habit is required.
