Fuel Tank Leak Detection System (EVAPS) (Freelander 1)

Fuel Tank Leak Detection System (EVAPS): Leak Detection, for North American market countries.

The exact location of a fuel tank leak, if the leak has caused the MIL to come on, can be determined using the following sequence of steps. The leak search should be performed once all other components in the system are found to be normal.

Examination

1. Check the Fuel supply and Toxicity Reduction System (EVAP) components for obvious damage. Check that all connections are securely sealed.

2. The check is carried out using the diagnostic installation LRA-19-004.

3. Disconnect the atmosphere connection hose from the canister purge valve and connect the LRA-19-004/1 adapter.

NOTE: The reason for using an adapter on the purge valve is that there is currently no dedicated diagnostic socket on the Freelander.

4. Remove the plastic mudguard of the right rear wheel.

5. Loosen the clamp and disconnect the hose from the carbon adsorber.

CAUTION: Before disconnecting any part of the fuel system, thoroughly clean the surrounding area of dirt, dust and deposits to prevent foreign particles from entering the system.

6. Close the hole in the adsorber with the plug included in the LRA-19-004 kit.

7. Attach the LRA-19-004 unit to the adapter on the purge valve.

8. Check the fuel supply system following the instructions supplied with the LRA-19-004 unit.

Adjustment

1. If a leak is found, replace the relevant component and retest to confirm that the fault has been corrected.



2. Remove the plug from the adsorber.

3. Place the hose on the adsorber and secure it with a clamp.

4. Install the rear wheel arch liner.
