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

The No. 2 turbo pressure sensor is installed to the intake manifold and detects the turbo pressure.

When the engine switch is turned on (IG) or the engine is idling, the pressure detected by the No. 2 turbo pressure sensor and the atmospheric pressure sensor built into the ECM will both be the same as atmospheric pressure.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P00CF62 Barometric Pressure - Turbocharger / Supercharger Boost Sensor "A" Signal Compare Failure Difference between atmospheric pressure value of the No. 2 turbo pressure sensor and atmospheric pressure sensor is higher than threshold value (1 trip detection logic).

  • No. 2 turbo pressure sensor

  • Intake system

  • Wire harness or connector

  • ECM

 Comes on DTC stored SAE Code: P00CF

MONITOR DESCRIPTION

When the engine switch is turned on (IG) or the engine is idling, the pressures detected by the No. 2 turbo pressure sensor and the atmospheric pressure sensor (built into the ECM) are compared. If the difference in the pressures detected is higher than threshold value, the ECM determines that the No. 2 turbo pressure sensor or atmospheric pressure sensor may be malfunctioning. In this case, the ECM illuminates the MIL and stores this DTC.

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.

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

      B003TXZ

      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 depending on the weather.

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

      Tech Tips


      • Use the table below for reference only.
