SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P106A62, P106C62

DTC Code DTC Name
P106A62 Evaporative Emission System Pressure / Intake Air Pressure Signal Compare Failure
P106C62 Evaporative Emission System Pressure/Barometric Pressure 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
P106A62 Evaporative Emission System Pressure / Intake Air Pressure Signal Compare Failure The difference between the pressure of the canister pressure sensor (Vapor Pressure Pump*) and manifold absolute pressure sensor (Intake Manifold Absolute Pressure*) is higher than 7.23 kPa (1.04 psi) (2 trip detection logic).

  • Canister pressure sensor (canister pump module)

  • Manifold absolute pressure sensor

 Comes on DTC stored SAE Code: P106A
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 10 kPa (1.45 psi) (2 trip detection logic).

  • Canister pressure sensor (canister pump module)

  • Atmospheric pressure sensor (ECM)

 Comes on DTC stored SAE Code: P106C

*: 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


  • *: P106A62 checks the canister pressure sensor and the manifold absolute pressure sensor. P106C62 checks the canister pressure sensor and atmospheric 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

ECM (atmospheric pressure sensor)

Manifold absolute pressure sensor
Frequency of Operation Continuous

CONFIRMATION DRIVING PATTERN


  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. Start the engine and idle for 10 seconds or more [A].

  7. Turn the engine switch off.

  8. Leave the engine switch off for 55 minutes [B].

  9. Turn the engine switch on (IG).

  10. Turn the GTS on.

  11. Enter the following menus: Powertrain / Engine / Trouble Codes [C].

  12. 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.

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

  14. Input the DTC: P106A62 or P106C62.

  15. 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, perform steps [A] through [C] again.

CAUTION / NOTICE / HINT

Tech Tips


  • Refer to "Data List / Active Test" [Atmospheric Pressure, Intake Manifold Absolute Pressure and Vapor Pressure Pump].

  • 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 P106A62 AND/OR P106C62)


    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.


      Powertrain > Engine > Trouble Codes
      Result
      Result Proceed to
      DTC P106A62 is output A
      DTC P106C62 is output B
      DTC P106A62 and P106C62 are output C
      DTC P106A62 and/or P106C62 and other DTCs are output D

      Tech Tips

      If any DTCs other than P106A62 and/or P106C62 are output, troubleshoot those DTCs first.
