MONITOR DESCRIPTION
In sequence B and E, the leak detection pump creates negative pressure (vacuum) through the reference orifice. The EVAP system pressure is then measured by the ECM, using the canister pressure sensor, to determine the reference pressure. If the pressure detected meets one of the following conditions, the ECM will illuminated the MIL and store a DTC (2 trip detection logic).
-
EVAP pressure is lower than the malfunction criterion.
-
EVAP pressure is higher than the malfunction criterion.
-
EVAP pressure is not saturated within 60 seconds.
-
EVAP pressure difference between sequence B and E is large.
MONITOR STRATEGY
| Required Sensors/Components | Canister pump module |
| Frequency of Operation | Once per driving cycle |
CONFIRMATION DRIVING PATTERN
-
The Evaporative System Check (Automatic Mode) consists of 9 steps performed automatically by the GTS. It takes a maximum of approximately 40 minutes.
-
Do not perform the Evaporative System Check when the fuel tank is higher than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.
-
Do not start the engine during this operation.
-
When the temperature of the fuel is 35°C (95°F) or higher, a large amount of vapor will from and any check result will be inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).
-
Connect the GTS to the DLC3.
-
Turn the power switch on (IG).
-
Turn the GTS on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the power switch off and wait for at least 30 seconds.
-
Turn the power switch is on (IG) and turn the GTS on.
-
Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode.
-
After the "Evaporative System Check" is completed, check for All Readiness by entering the following menus: Powertrain / Engine / Utility / All Readiness.
-
Input the DTC: P043E00, P043F00, P24007E, P24007F or P24187E.
-
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
Tip:
-
If the judgment result shows NORMAL, the system is normal.
-
If the judgment result shows ABNORMAL, the system is malfunctioning.
-
CAUTION / NOTICE / HINT
-
Vehicle Control History may be stored in the hybrid vehicle control ECU 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.)
-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, 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.
