SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P106C62, P106D62

DTC Code DTC Name
P106C62 Evaporative Emission System Pressure/Barometric Pressure Signal Compare Failure
P106D62 Evaporative Emission System Pressure Sensor - Turbocharger/Supercharger Boost Sensor Signal Compare Failure

DESCRIPTION

Those DTCs are designed to detect a deviation in the output characteristics of a pressure sensor.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P106C62 Evaporative Emission System Pressure/Barometric Pressure Signal Compare Failure The difference between the pressure of the canister pressure sensor (Vapor Pressure Pump*) and atmospheric pressure sensor (Atmospheric Pressure*) is Higher than 7.89 kPa [1.14 psi] (2 trip detection logic).

  • Canister pressure sensor (canister pump module)

  • atmospheric pressure sensor (ECM)

 Comes on DTC stored SAE Code: P106C
P106D62 Evaporative Emission System Pressure Sensor - Turbocharger/Supercharger Boost Sensor Signal Compare Failure The difference between the pressure of the canister pressure sensor (Vapor Pressure Pump*) and boost pressure sensor (Boost Pressure Sensor*) is Higher than 12.4 kPa [1.80 psi] (2 trip detection logic).

  • Canister pressure sensor (canister pump module)

  • No. 2 turbo pressure sensor

 Comes on DTC stored SAE Code: P106D

*: Data List name

MONITOR DESCRIPTION

Those DTCs are stored when a deviation from pressure sensor characteristics is detected.

The pressure sensors* are checked approximately 50 minutes after the engine switch is turned off. If the pressures detected by the pressure sensors* differ by a certain amount, the MIL is illuminated and a DTC is stored (2 trip detection logic).

Tech Tips


  • *: P106C62 checks the canister pressure sensor and atmospheric pressure sensor. P106D62 checks the canister pressure sensor and the No. 2 turbo pressure sensor (boost pressure sensor).

  • Correct judgment may not be possible when the altitude is 4000 m (13120 ft.) or more.

MONITOR STRATEGY

Required Sensors/Components

Canister pressure sensor

Atmospheric pressure sensor

No. 2 turbo pressure sensor
Frequency of Operation Continuous

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

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

  4. Start the engine and idle for 10 seconds [B].

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

  6. Leave the engine switch off for 55 minutes or more [C].

  7. Turn the engine switch on (IG) and turn the GTS on.

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

  9. 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.

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

  11. Input the DTC: P106C62 or P106D62.

  12. 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
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


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

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform steps [B] through [D].

CAUTION / NOTICE / HINT

Tech Tips


  • Refer to "Data List / Active Test" [Atmospheric Pressure, Vapor Pressure Pump and Boost Pressure Sensor].

  • 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 P106C62 AND/OR P106D62)


    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.

      Result
      Result Proceed to
      DTC P106C62 is output A
      DTC P106D62 is output B
      DTC P106C62 and P106D62 are output C
      DTC P106C62 and/or P106D62 and other DTCs are output D

      Tech Tips

      If any DTCs other than P106C62 and/or P106D62 are output, troubleshoot those DTCs first.
