SFI SYSTEM, Diagnostic DTC:P00CF62

DTC Code DTC Name
P00CF62 Barometric Pressure - Turbocharger / Supercharger Boost Sensor "A" Signal Compare Failure

DESCRIPTION

The No. 1 turbo pressure sensor is installed between the intercooler and throttle body with motor assembly and measures the internal pressure of the intercooler. When the ignition switch is ON or the engine is idling, the No. 1 turbo pressure sensor and the atmospheric pressure sensor build into the ECM detect atmospheric pressure and output same value.

Barometric Pressure - Turbocharger / Supercharger Boost Sensor "A" Signal Compare Failure

Difference between atmospheric pressure value of the No. 1 turbo pressure sensor and atmospheric pressure sensor is 15 kPa (2.18 psi) or higher (1 trip detection logic).

  • No. 1 turbo pressure sensor

  • Wire harness or connector

  • Intake system

  • ECM

SAE Code: P00CF

MONITOR DESCRIPTION

When the ignition switch is turned to ON or the engine is idling, the pressures detected by the the No. 1 turbo pressure sensor and the atmospheric pressure sensor built into the ECM are compared. If the difference in the pressures detected is 15 kPa (2.18 psi) or higher, the ECM determines that the No. 1 turbo pressure sensor or atmospheric pressure sensor may be malfunctioning. In this case, the ECM illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN

  1. Connect the GTS to the DLC3.

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

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the ignition switch off and wait for at least 30 seconds.

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

  6. Start the engine and wait 5 seconds or more.

  7. Enter the following menus: Powertrain / Engine / Trouble Codes.

  8. Read the pending DTCs.

    Tip:

    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  9. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  10. Input the DTC: P00CF62.

  11. Check the DTC judgment result.

CAUTION / NOTICE / HINT

Tip:

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P00CF62)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Trouble Codes.

    5. Using the following table, determine the normal atmospheric pressure for the current altitude and temperature.

      A337505
      Tip:

      • Standard atmospheric pressure is approximately 101 kPa(abs) (14.65 psi(abs)).

      • For every 100 m (328 ft.) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies depending on the weather.

    6. Compare the values of Atmospheric Pressure and Boost Pressure Sensor with the normal atmospheric pressure in the table.
