SFI SYSTEM(w/o Canister Pump Module), Diagnostic DTC:P00CF62

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

DESCRIPTION

At engine switch on (IG) or during idling, the No. 2 turbo pressure sensor and the atmospheric pressure sensor built into the ECM are at atmospheric pressure and their outputs match.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P00CF62 Barometric Pressure - Turbocharger / Supercharger Boost Sensor "A" Signal Compare Failure 15 kPa [2.18 psi] or greater difference between the atmospheric pressure values of the No. 2 turbo pressure sensor and the atmospheric pressure sensor (1 trip detection logic).

  • No. 2 turbo pressure sensor

  • Wire harness or connector

  • ECM

 Comes on DTC stored SAE: P00CF

MONITOR DESCRIPTION

At engine switch on (IG) or during idling, the output values from the No. 2 turbo pressure sensor and the atmospheric pressure sensor built into the ECM are compared. If the difference in atmospheric pressure values is 15 kPa [2.18 psi] or greater, there may be a malfunction in the No. 2 turbo pressure sensor and atmospheric pressure sensor. In this case, the ECM illuminates the MIL and stores a DTC.

  8. Read the pending DTCs.

    Tech Tips


    • 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

Tech Tips

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 engine switch on (IG).

    3. Turn the GTS on.

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

    5. Read the DTCs.

      Tech Tips

      If any DTCs other than P00CF62 and P023400, P023562, P211900, P211904 or P211977 are output, troubleshoot those DTCs first.

    4. Using the table, read the normal atmospheric pressure value for the applicable altitude and temperature.

      B008ILG

      Tech Tips


      • 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 by weather.

    5. Compare the Atmospheric Pressure and Boost Pressure Sensor values in the Data List with the normal atmospheric value from the table.

      Result

      Difference between (difference between Boost Pressure Sensor in the Data List and normal atmospheric pressure) and (difference between Atmospheric Pressure in the Data List and normal atmospheric pressure) is 4 kPa [0.58 psi] or greater A
      Other than above B

      Tech Tips


      • As the table below shows reference values only, use actual values for calculations.

      • In Example 1, as the pressure difference is 4 kPa [0.58 psi] or higher, proceed to the next step.

      • In Example 2, as the pressure difference is less than 4 kPa [0.58 psi], replace the ECM.
