Both of the following conditions (a) and (b) are met for 10 seconds or more (2 trip detection logic):

(a) The purge VSV operation duty signal is 0%.

(b) The amplitude of the No. 2 turbo pressure sensor (bank 1) output voltage is at the threshold or higher.

  • Open or short in No. 2 turbo pressure sensor (bank 1) circuit

P2B7A1F EVAP System Pressure Sensor/Switch "C" Circuit Intermittent Circuit Intermittent

Both of the following conditions (a) and (b) are met for 10 seconds or more (2 trip detection logic):

(a) The purge VSV operation duty signal is 0%.

(b) The amplitude of the No. 2 turbo pressure sensor (bank 2) output voltage is at the threshold or higher.

  • Open or short in No. 2 turbo pressure sensor (bank 2) circuit

  • No. 2 turbo pressure sensor (bank 2)

  • ECM

 Comes on DTC stored SAE: P2B7E

MONITOR DESCRIPTION

During fuel cut, the No. 2 turbo pressure sensor output voltage stabilizes because the purge VSV is stopped.

When the amplitude of the No. 2 turbo pressure sensor output voltage is at the threshold or higher during fuel cut, a malfunction in the No. 2 turbo pressure sensor is judged, and the ECM illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN

B006FO6E13

  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG).

  3. Turn the GTS on.

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

  5. Turn the engine switch off and wait for at least 30 seconds.

  6. Turn the engine switch on (IG).

  7. Turn the GTS on.

  8. Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher [A].

  9. Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [B].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    Tech Tips

    Drive the vehicle while keeping the engine load as constant as possible.

  10. Using the GTS, enter the following menus to check the fuel-cut status: Powertrain / Engine / Data List / Idle Fuel Cut.

  11. With the shift state M selected, drive the vehicle at 60 km/h (37 mph), and then decelerate the vehicle by releasing the accelerator pedal for 10 seconds or more to perform the fuel-cut [C].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    Tech Tips

    While "Idle Fuel Cut" on the Data List is ON, fuel-cut control is being executed.

  12. Repeat step [C] 2 times or more in one driving cycle.

  13. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending [D].

  14. 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.

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

  16. Input the DTC: P24D51F or P2B7A1F.

  17. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    Tech Tips


    • If the judgment result is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system is malfunctioning.

    • If the judgment result is INCOMPLETE, drive the vehicle with the shift state M, and then perform step [C] again.

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.

  • Bank 1 refers to the bank that includes the No. 1 cylinder*.

    *: The No. 1 cylinder is the cylinder which is farthest from the transmission.

  • Bank 2 refers to the bank that does not include the No. 1 cylinder.
