Code P0442 - Replaced Purge Valve - ??

[RickMar]

Hi;
Thank you for taking the time to read this thread.
I have a 1999 Murcury Mountaineer.
I had the state inspection on Mounty and it failed emissions.
Code P0442 put an end to the inspection and a big "R" sticker is on the windshield.
Code P0442 is Gas Cap, Vacuum leak or purge valve.
Figuring the gas cap and vacuum leak aren't too difficult to fix, I replaced the Purge Valve located under the battery box.
I read something somewhere in this forum and I can not locate it which explained something about driving the mounty a certain way at different speeds stopping then accelerating to 45 M.P.H. / 60 M.P.H. and letting it coast down to a stop.
I am not sure how it went exactly.
My question is ...Although the check engine light is out, do I need to go through any driving procedure to clear out the code P0442?
Any information will be very much appreciated.
Thank you;
Rick

I know this is an old thread, but here's the drive cycle you use to quick cycle the computer for inspection.

NYS DMV - (Brochure) DRIVE NY CLEAN
1. The OBDII drive cycle begins with a cold start (coolant temperature below 122
degrees F and the coolant and air temperature sensors within 11 degrees of
each other).
2. The ignition key must not be left on prior to the cold start - otherwise the heated
oxygen sensor diagnostic may not run.
3. As soon as the engine starts, idle the engine in drive for two and one-half
minutes, with the air conditioning (A/C) and rear defrost turned on, if
equipped.
4. Turn the A/C and rear defrost off, and accelerate to 55 mph under
moderate, constant acceleration. Hold at a steady speed of 55 mph for
three minutes.
5. Decelerate (coast down) to 20 mph without braking (or depressing the
clutch for manual transmissions).
6. Accelerate again back to 55 to 60 mph.
7. Hold at a steady speed of 55 to 60 mph for five minutes. Decelerate
(coast down) to a stop without braking.

If you're unable to do all of these steps, doing steps 1 through 5 from a cold start will accomplish the same thing.
