Just recently brought the car from a dealer a week ago. Was all fine, I put in 500 miles in it already so I can get my extended warranty to kick in sooner(need to put in 1k miles). I drove the car until it had 1 bar last night. I pump it this morning to full and drove it right back home about 3miles. Let it sit for 5 hrs went to work 15 miles out, no problems so far. Off work,half out from home on the highway cel pop up. Pulled up the code P04907 low evap. So I deleted re tightening my gas cap and drove it to my house from my buddy house 2miles. Now I'm just waiting till I meet the conditions of the cel to come back or not. Any other problems to this solution? I read that it could be the purge solenoid or canister or vent valve. Car is a 05 ap2 97k I'm second owner, car was well maintain from previous owner. All maintenence done by honda and I mean all maintenence. Just wanted to see if anyone dealt with this problem and how they came about it. Is there a guide on how to clean or replace the solenoid?

 

Loose gas cap code is about the only code I've seen in my 04 AP2. Clear the code and drive another few months...good to go!

 

Alright after 7 months now the code is back...I change out gas cap with a buddy's car and it still came back on. Put back my old gas cap it was fine until I put a brand new oem cap on. Now I'm thinking it the canister or something else. Not really good with evap diagnosis. Can someone help by what to look for first. I check the hoses by manifold and it seems to just have white residue inside of it. I did a quick check on the canister under the car and everything seems to be fine. Help me out guys.. also when I delete this code on PENDING MODE while the car is running I get a p0410 code that won't go away unless I turn off my car and turn it back on

 

just saw that this hose was sticky. could this hose be causing the cel?

 

What does a sticky hose mean?

 

I'll change out this hose on wed. See if that fixed it. Is there anyway to clean the vent tube too?

 

You define sticky hose, I'll tell you how to fix the car instead of changing a part that wont.

 

so when I was checking all my hoses I notice that the hose in the picture was sticky (like touching dry soda),on the outside where it connects to the tube and didn't seem to have a tight fit.i figure it must be leaking there otherwise the hose would just have that dirty rough feel to it. So what should I be looking for

 

so i havent replace anything, i probably deleted the pending code 4 or 5 times already in the past 4 days. weird cause i took my car for a drive in the mountains yesterday and it never once came on. im running a ultragauage to monitor my cel. it was probably a 80mile drive to there and coming back. usually i would get a pending code after 20miles of driving. gas tank is 1/4 full too. maybe it was clogged? ill keep monitoring after i pump gas, usually itll come back on then lol.
