Emission Control Land Rover Freelander L314

17.90.02.01 Evaporative loss control system (EVAPS) - leak test - NAS

The following procedure allows a fuel leak, indicated by the Malfunction Indicator Lamp (MIL), to be accurately located. It must only be carried out once it has been established that there are no obvious faults with any of the system components.

Check

1. Check components in fuel and EVAP system for obvious damage. Ensure all connections are properly secured.
2. The system must be checked using a EVAPS Diagnostic Testing Station LRA-19-004.
3. Disconnect vent pipe from purge valve and connect adapter LRA-19-004/1. NOTE: The reason for inserting the adapter into the purge valve is that there is currently no service port fitted to Freelander.
4. Remove RH rear wheel arch liner. Refer to «REMOVE»(/land-rover/freelander/l314-2003-2006/remont/exterior-body-panels/#exterior-fittings) .
5. Release clip and disconnect hose from charcoal canister. CAUTION: Before disconnecting any part of the fuel system, it is imperative that all dust, dirt and debris is removed from around components to prevent ingress of foreign matter into fuel system.
6. Block charcoal canister port with bung, included in LRA-19-004.
7. Connect LRA-19-004 to service port fitted on purge valve.
8. Carry out procedures given in the operating instructions, these are supplied with LRA-19-004.

Adjust

1. If a leak has been detected, replace component as necessary and repeat leak test to validate repair.
2. Remove bung from charcoal canister.
3. Connect hose to charcoal canister and secure with clip.
4. Fit rear wheel arch liner. Refer to «REFIT»(/land-rover/freelander/l314-2003-2006/remont/exterior-body-panels/#exterior-fittings) .
