DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P0299 Turbocharger / Supercharger Underboost The pressure is 55 kPa below the Target Booster Pressure for 80 seconds at an engine speed of 2800 to 4400 rpm (2 trip detection logic).

  • Turbocharger sub-assembly

  • Extremely low battery voltage (P0560 output simultaneously)

  • Disconnected pipe between turbo and intake manifold

  • Disconnected manifold absolute pressure sensor hose

  • Throttle valve stuck closed

  • Electric EGR control valve assembly does not close

  • Exhaust system or intake system modified (leading to increased pressure loss, etc.)

  • Manifold absolute pressure sensor

  • Injection system (reduction in fuel injection volume)

  • ECM

  • Target Booster Pressure

  • MAP
Tip:

  • If DTC P0299 is stored due to the variable nozzle being stuck open, the following symptoms may appear:

    • Lack of power

    • Vehicle surge or hesitation under light or medium load

CONFIRMATION DRIVING PATTERN

DTC No. DTC Detection Drive Pattern
P0299 Accelerate vehicle with accelerator depressed halfway or more starting from a speed of 120 km/h (75 mph) or more for 2 minutes (make sure gear is fixed and does not change)

CAUTION / NOTICE / HINT

Note:
Tip:

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

  • Comparison of the data list items MAP and Target Booster Pressure during acceleration under medium to high engine speeds can be used to determine the state of the problem.

PROCEDURE

  1. CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0299)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    4. Read the DTCs.

      Tip:

      If any DTCs other than P0299 are output, troubleshoot those DTCs first.

  2. CHECK FREEZE FRAME DATA (FUEL PRESS AND TARGET COMMON RAIL PRESSURE)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    4. Record the stored DTC and freeze frame data.
