| DTC Code | DTC Name |
|---|---|
| P24507E | Evaporative Emission System Switching Valve Actuator Stuck On |
| P24517F | Evaporative Emission System Switching Valve Actuator Stuck Off |
DTC SUMMARY
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P24507E | Evaporative Emission System Switching Valve Actuator Stuck On | Either of the following conditions is met when fuel tank pressure is between -2 and 3 kPa(gauge) [-0.29 and 0.44 psi(gauge)].
|
|
Comes on | DTC stored | SAE: P2450 |
| P24517F | Evaporative Emission System Switching Valve Actuator Stuck Off | Either of the following conditions is met:
|
|
Comes on | DTC stored | SAE: P2451 |
| DTC No. | Monitoring Item | Detection Timing | Detection Logic | SAE |
|---|---|---|---|---|
| P24507E | Fuel vapor-containment valve stuck open | EVAP monitoring (power switch off) |
2 trip | P2450 |
| P24517F | Fuel vapor-containment valve stuck close | P2451 |
MONITOR DESCRIPTION
P24507E: Fuel vapor-containment valve stuck open
During sequence C, the leak detection pump creates vacuum in the EVAP system. If the pressure in the fuel tank drops, the ECM determines that the fuel vapor-containment valve is stuck open, illuminates the MIL and stores the DTC (2 trip detection logic).
P24517F: Fuel vapor-containment valve stuck closed (vent)
During sequence I, the fuel vapor-containment valve opens to allow atmospheric pressure into the fuel tank. If there is no change in fuel tank pressure, the ECM determines that the fuel vapor-containment valve is stuck closed, illuminates the MIL and stores the DTC (2 trip detection logic).
During sequence G, the fuel vapor-containment valve opens to allow vacuum pressure generated by the leak detection pump into the fuel tank. If the pressure in the fuel tank does not drop, the ECM determines that the fuel vapor-containment valve is stuck closed, illuminates the MIL and stores the DTC (2 trip detection logic).
MONITOR STRATEGY
| Required Sensors/Components | Fuel vapor-containment valve Fuel tank pressure sensor Canister pump module |
| Frequency of Operation | Once per driving cycle |
CONFIRMATION DRIVING PATTERN
Note
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 more 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: P24507E or P24517F.
Check the DTC judgment result.

Tech Tips
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system is malfunctioning.
CAUTION / NOTICE / HINT
Note
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.
