*: 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 ignition 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.
HINT:
- *: P106A62 checks the canister pressure sensor and the No. 3 turbo pressure sensor. P106C62 checks the canister pressure sensor and atmospheric pressure sensor. P106D62 and P106F62 check the canister pressure sensor and the No. 1 turbo pressure sensor. P109E62 check the canister pressure sensor and the vacuum sensor assembly.
- Correct judgment may not be possible when the altitude is 4000 m (13120 ft.) or more.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON.
- Turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Start the engine and idle for 10 seconds or more [A].
- Turn the ignition switch off.
- Leave the ignition switch off for 55 minutes [B].
- Turn the ignition switch to ON.
- Turn the GTS on.
- Enter the following menus: Powertrain / Engine / Trouble Codes [C].
-
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.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P106A62, P106C62, P106D62 or P109E62.
-
Check the DTC judgment result.

Description
NORMAL
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- 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.
-
[A] to [C]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
CAUTION / NOTICE / HINT
HINT:
-
Refer to "Data List / Active Test" [Atmospheric Pressure, Intake Manifold Absolute Pressure, Vapor Pressure Pump, Boost Pressure Sensor and PCV 1 Pressure].

- 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.
