4 PL FUEL SYSTEM

Inspection :

Remove fuel filler cap.

If check result is not satisfactory, check for vaccum

hose, purge valve, wire harness etc. Check carbon

canister for signs of damage and defects.

If defective, replace canister.

If OK, go to step 3

Warmup engine to normal operating temperature.

Disconnect “purge” end hose (from the canister to

purge valve)

a) Place finger against the end of disconnected

hoses. Check that vaccum is felt there when

engine is running at idle speed.

b) Alsocheck that vaccum is feltwhenengine speed

is increased to higher than 2000/3000rpm.

Start engine and run it at idle speed. Disconnect

vaccum hose(from canister purge valve to T

Connector). Block the T connector port fromwhere

the hose has been removed, with finger placed

against the hose disconnected. Check that vaccum

is applied. If it is not applied clean vaccum passage

by blowing compressed air.

Assembly :

For hose connection refer schematic circuit diagram.

Fig. 2 .The canister port consists of marking“purge” and

“tank”. Fig. 24.

e) Canister purge Valve : Fig. 25, 26

The canister purge valve is controlled by engine

management system (EMS).

The purging of canister takes place because of

pressure differential betweenmanifold vacuumand

atmosphere. Fuel vapours are drawn into the intake

manifold through canister purge valve operated by

ECU.

Removal :

Disconnect hose from canister purge valve to

T connector.

Disconnect the hose fromcanister to purge valve

from canister “purge”end.
