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 8.69 kPa (1.26 psi) (2 trip detection logic). |

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). |

*: 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 (2 trip detection logic).
HINT:
- *: 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.

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 Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream 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.
- Turn the ignition switch to ON.
- Turn the Techstream on.
-
Put the engine in Inspection Mode (Maintenance Mode).
Click here
- 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 Techstream 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 or P106C62.
-
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 auxiliary 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
NOTICE:
-
Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

(Select Powertrain in Health Check and then check the time stamp data.)
Click here
-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:
-
Refer to "Data List / Active Test" [Atmospheric Pressure, Intake Manifold Absolute Pressure and Vapor Pressure Pump].
Click here
- Read Freeze Frame Data using the Techstream. 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.
