EVAP System Tank Vapor Line Restricted/Blocked |
Leak detection pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure is measured. When the fuel level in the fuel tank is 85% or less and the leak detection pump is operating, the EVAP system pressure decreases quickly. |

MONITOR DESCRIPTION
5 hours* after the ignition switch is turned off, the leak detection pump creates negative pressure (vacuum) in the EVAP (Evaporative Emission) system. The ECM monitors for leaks and actuator malfunctions based on the EVAP pressure.
HINT:
*: If the engine coolant temperature is not less than 35°C (95°F) 5 hours after the ignition switch is turned off, the monitor check starts 2 hours later. If it is still not less than 35°C (95°F) 7 hours after the ignition switch is turned off, the monitor check starts 2.5 hours later.

Operation |
Description |
Duration |
|---|---|---|---|
|
- |
ECM activation |
Activated by soak timer 5, 7 or 9.5 hours after ignition switch turned off. |
- |
|
A |
Atmospheric pressure measurement |
Vent valve is turned off (vent) and EVAP system pressure is measured by ECM in order to register atmospheric pressure. If pressure in EVAP system is not between 70 to 110 kPa(abs) [10.15 to 15.95 psi(abs)], ECM cancels EVAP system monitor. |
60 seconds |
|
B |
First reference pressure measurement |
In order to determine reference pressure, leak detection pump creates negative pressure (vacuum) through reference orifice and then ECM checks if leak detection pump and vent valve operate normally. |
360 seconds |
|
C |
EVAP system pressure measurement |
Vent valve is turned on (closed) to shut EVAP system. Negative pressure (vacuum) is created in EVAP system, and EVAP system pressure is then measured. Write down measured value as it will be used in leak check. If EVAP pressure does not stabilize within 15 minutes, ECM cancels EVAP system monitor. |
15 minutes* |
|
D |
Purge VSV monitor |
Purge VSV is opened and then EVAP system pressure is measured by ECM. Large increase indicates normal. |
10 seconds |
|
E |
Second reference pressure measurement |
After second reference pressure measurement, leak check is performed by comparing first and second reference pressure measurements. If stabilized system pressure is higher than second reference pressure, ECM determines that EVAP system is leaking. |
60 seconds |
|
- |
Final check |
Atmospheric pressure is measured and then monitoring result is recorded by ECM. |
- |
*: If only a small amount of fuel is in the fuel tank, it takes longer for the EVAP pressure to stabilize.

During operation C, if the EVAP system pressure is below the threshold after 20.3 seconds*1 or 29.2 seconds*2, the ECM will determine that there is blockage between the fuel tank and canister, illuminate the MIL and store this DTC (2 trip detection logic).

CONFIRMATION DRIVING PATTERN
NOTICE:
- The Evaporative System Check (Automatic Mode) consists of 6 steps performed automatically by the Techstream. It takes a maximum of approximately 24 minutes.
- Do not perform the Evaporative System Check when the fuel tank is higher than 85% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.
- Do not run the engine during this operation.
- When the temperature of the fuel is 35°C (95°F) or higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).
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 [A].
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode [B].
- After the Evaporative System Check is completed, check for All Readiness by entering the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P00FE00.
-
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.
-
[A] to [B]: 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.
