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

SAE: P00CF

MONITOR DESCRIPTION

At ignition switch to ON 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 stores a DTC.

  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.

    HINT:

    • 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.

CAUTION / NOTICE / HINT

HINT:

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)

(a) Read the DTCs.

Powertrain > Engine > Trouble Codes

(b) Using the table, read the normal atmospheric pressure value for the applicable altitude and temperature.

HINT:

  • 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.

(c) Compare the Atmospheric Pressure and Boost Pressure Sensor or Boost Pressure Sensor2 values in the Data List with the normal atmospheric value from the table.

Result

Proceed to

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

HINT:

  • 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.
