I have a 2008 CRV that had the exact symptoms. It started with the gas cap warning for about a month. (A new gas cap didn't solve the problem) Then the engine light came on with the codes P145C and P0497. My checking of the purge solenoid was not as sophisticated. I took the solenoid out and checked it on my bench with a 12 volt supply. (To remove the solenoid getting the bottom screw out wasn't fun) I just blew threw it and then applied 12v. I was dissapointed because I found it seemed to be working fine.
Not having anything to lose other than the 40 for a new solenoid, I decided to change it anyway. Much to my surprise after driving about 5k (yes I'm in Canada) the check fuel cap stopped flashing and no engine light!
Thanks so much for the tip. The Honda dealer wanted 90 just to diagnose the problem. Great video.

Hey there - working on a 2004 CR-V with ONLY a P0497 code set. PCS tests good and nothing else visibly wrong. Unfortunately, no access to a smoke machine as I am DIY and not a pro.
Found the Honda FSM for my model with ZERO reference to the P0497 DTC.
Any ideas of where to go next?
Next weekend I am going to crawl under it and check everything related to the canister just to be sure, but it seems like the wrong DTC for canister or vent related issues. Trusting the PCM here, maybe foolish, maybe not.
Thanks in advance!

Thanks for the video. I have this code(P0497) on Acura MDX 2003, I will start by replacing gas cap and then solenoid, what next? The reason I ask is, the diagnostic cost is probably the same as sum of all parts(I will do all the labor work. I rather spend some extra dollars and put in new parts versus spend 2 hours for diog only to do this again next year. Please let me know your thoughts.
EDit: purge solenoid ticking and this code pretty much came in at the same time.

hi there I'm from Barrie I have a 05 1. 7 L Honda civic I've replaced the Catalytic converter manifold studs and gasket plus muffler. I have a p0497 low purge flow code so I also replaced the canister purge valve solenoid, after I replaced it I was wrong on my diagnosis, because the code returned. I checked the vacuum line coming from the manifold, there is vacuum I'm not sure what my next step should be as far as diagnosis goes

Great video. i just bought an 07 CR-V for my wife yesterday and the Check fuel Cap was flashing on dash. Today the Check engine light came on. Checked codes and it came back with the po497 and p145C. I did the test on the purge valve by using vacuum pump and 2 jumpers from battery direct to valve and it opened. i did check vacuum from engine and is good. . now what? An answer is greatly appreciated. Thanks. .

Right now I have the check fuel cap. I was going to replace. the cost is 45. the other day I got the check engine with the P145C code. Came out of my appointment and the check engine light was off and the check fuel cap was back on. Don't want to waste 45 on a fuel cap if its something else. could the faulty part described in the video be throwing an error that doesn't relate to the cap?

Thank you for your logical explanation! Also, thank you for explaining that you could power the solenoid without a scan tool! You are obviously a seasoned mechanic. Too many don't know WHY they do what they do, they just replace parts and cross their fingers. You also put in the time to verify that the condition was not due to another issue further back in the fuel system. A+

Great video. Straight to the point, and sweet testing instructions. I've narrowed it down to that on my 09. Took top of air cleaner box and filter off to get a screwdriver in there. These things are NOT moving. Ok to shoot it with some penetrating oil over night and replace when the engine is good and cold? Or is there a better way to attack this thing? Thanks!

My sisters 2011 CRV was spitting out P1450 and P0497. I took a gamble and bought the part rather than buy a vacuum pump and test the component. This solenoid was the culprit. I paid 68 CAD vs 260+ at the dealer. Thank you for helping us both out.
