P0446

[1997xltlimited]

I have a P0446 engine code do I need to replace both the Purge Valve and the Vapor canister. Or just the Purge valve itself?

P0446 indicates problem with the Vent Valve.

I would remove, clean out & bench test before spending money on new unit.

Can you please explain how to bench test the valve.

 

 

Thanks

...how to bench test the valve.

Remove valve. Blow it out (in case there's any crud therein). Hook up to a 12V power supply (it's a simple solenoid valve - either open or closed).

Blow through it energized / de-energized; it should blow "free" de-energized & "block" airflow when energized.

So true! I had the code and the check engine light.

I just disconnected/reconnected the elec. plug checked for

crud in the tube connections and cleared the code.

 

The part is less than $30 bucks and can be found at most parts houses.

Be aware some dealers will try and sell you the $200 relocate kit and

solenoid instead of the $30 solenoid.
