11.8 - Purge Valve ( )

Fuel code 89, purge valve.

It's supposed to put a vacuum to the charcoal canister to suck out all those nasty gas fumes that build up in the tank and go into the canister instead of the air.

It's on the drivers side, above the charcoal canister behind the headlight.

The ECM looks at the O 2 sensor for a change when the purge valve is open, no change = check engine.

Purge drive circuit probably means connection or valve malfunction.

The valve can easily be checked by switching ignition on and off. It makes a very loud click. You can also check with 12V directly across terminals which is easier if you haven't got a friend. i.e. two wires to battery but be careful with dangling wires etc.

You can checked valve operation by blowing down the tube off the manifold.
