I am keep getting this code P2422. I read few posts and majority of them answered spider web causing this code. But I did clean the EVAP located under the car but it is still coming up. The dealer will not fix this since the car is out of the warranty. How do I make this go away. Please help. Thank You.
Do you
have the same problem?

Product Update: EVAP Canister Drain Joint
(Supersedes 03-040, dated July 31, 2003)
BACKGROUND
In wet conditions, moisture can enter the EVAP
canister at its drain joint. This can cause the MIL to
come on with DTC P0497 (EVAP system low purge
flow) or DTC P2422 (EVAP system vent shut valve
close malfunction).
VEHICLES AFFECTED

Product Update: Intake Air Breather Pipe
(Supersedes 03-043, dated March 5, 2004)
BACKGROUND
The hose on the intake air breather pipe can cause the
pipe to separate from the airflow chamber during heavy
throttle applications. If this happens on a SULEV
model, it causes the MIL to come on with DTC P0171
(fuel supply system too lean).
VEHICLES AFFECTED
2003 Accord L4 2-Door:
From VIN 1HGCM7.3A000001
thru 1HGCM7.3A027598

Replace the intake air breather pipe and hose. (The
hose length has been increased 10 mm, and there is a
barb on the end of the air breather pipe to help retain
the hose.)

repair. If you do not have these tools, you can order

Thank you for your response. I will try this as soon as the weather turns good. Does this code cause any harms to the car engine and its performance meanwhile?

If left for long period of time (roughly more than 6 months), it will cause problem. In the mean time, you may notice slight decrease in performance or occasional erratic idle or jerks, but thing for sure, you will not pass emission/smog inspection. So, if your license plate is due any time soon, you need to fix the problem beforehand.

Let us know what happens.

You are actually correct, I have been noticing jerks when I let go on gas during driving, mostly at 10-30 mph. It feels like when you are in low gear and the car is trying to slow down itself. About emission, I am not due until Dec-09. I am now debating weather take it to dealer or just go to some local garage. Any advise?

Even though your vehicle is out of warranty, if you purchased the vehicle new, I would call Honda customer service hotline and find out if your vehicle is a part of the recall.

If you purchased it used, you have a choice to either go the dealership or local garage. But if I were you, I would bite the bullet and go back to the dealership to make sure that it is done right. This is not something that your local garage does on a regular basis.

Well finally I took it to dealership and as I suspected it was spider web. But the tech he can't clean it out, he would have to change the part. He quoted me 420 dollars + tax. I was wondering if it is possible to do this at home to save money. Does anyone have ever done something similar?
