Ford Ecosport: Evaporative Emissions - 2.0L Duratec-HE (129kW/175PS) / General Procedures - Evaporative Emission System Leak Test
Activation
Phase 1 - Leak Verification
-
Run the EVAP Test with the scan tool.
-
NOTE:
Some small leaks may not be detected using the EVAP Test. If the system
has passed the test but a leak is still suspected, then proceed to
Phase 2.
If the EVAP system failed the EVAP Test, then proceed to Phase 2.
Phase 2 - System Leak Check
-
Disconnect the fuel vapor tube-to-EVAP canister purge valve quick connect coupling.
Refer to: Quick Release Coupling (310-00C)
.
-
Connect the VACUTEC Smoke Machine Fuel EVAP Emissions System Tester to
the fuel vapor tube quick connect coupling. Refer to the manufacturer's
instructions.
-
NOTE:
The battery ground cable was previously
disconnected in the fuel vapor tube quick connect coupling procedure.
Connect the battery ground cable.
Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).
-
Close the canister vent solenoid with the scan tool.
-
NOTE:
The supplemental refueling adapter is located in the jack storage compartment.
Install the supplemental refueling adapter into the Easy FuelTM (capless) fuel tank filler pipe assembly.
-
NOTE:
If smoke does not exit the fuel tank filler pipe
neck area after the system is pressurized, open the canister vent
solenoid with the scan tool to allow the air to purge. Once smoke is
seen at the canister vent solenoid, close the canister vent solenoid
with the scan tool.
Introduce smoke from the VACUTEC Smoke Machine Fuel EVAP Emissions System Tester into the EVAP
system and verify that smoke is exiting the fuel tank filler pipe
neck area. For additional information, refer to the manufacturer's
instructions.
-
Remove the supplemental refueling adapter once smoke
is observed exiting the fuel tank filler pipe neck area.
-
Continue to enter smoke into the system for 60 seconds to obtain pressure.
-
Press and release the remote start button in
intervals of 15 seconds ON and 15 seconds OFF while checking for exiting
smoke.
-
Use the halogen light provided with the VACUTEC Smoke Machine Fuel EVAP
Emissions System Tester to follow the EVAP system path and look for
smoke exiting at the source of the leak(s).
-
Repair any leaks as necessary.
-
Repeat the leak test until the system passes.
