I replace everything even the charcoal canister same code car still running on limp mode probably have to get a new Cat converter is what I'm guessing 🤦🏽♂️
Same car, same code. I replaced the valve with a cheap aftermarket one, and all seemed fine for 400 km. Code appeared again, then replaced with a genuine Honda. Then I noticed the EVAP vacuum is only going to -0.65 kpa with 3500 rpm. Is there a blockage somewhere else? What would be a normal range for the EVAP pressure on this car?
No check engine light for me but I do have a check fuel cap light. However, my mechanic said he checked the purge valve and he didn't see anything wrong. Seems to be a common resolution so now I'm wondering if my mechanic is wrong.
Perfect timing for you to post this lol. My 2008 Honda civic stalled out on me about 2 days ago while I was delivering pizzas. I checked fuses, changed spark plugs n checked all my power/grounds. Cant get the thing to start, but it cranks strong. I ran a friends code reader and it came back with no codes. Doing some late night research and I remembered I had AutoZone run their scanner about a month ago, and I did get this code P0497 as the main issue. I ended up replacing my vtec solenoid gasket instead. I really don't want to get into the whole fuel pump project so could this be my issue? I had some noise coming from the motor that was nothing too worrying at the time, and I got my gas cap message on rare occasion. Thanks for sharing this!
I replaced the solenoid valve. Check engine light and Check fuel cap back on a couple of days later. Had the codes cleared and it returned. Did a diagnostic test from Auto Zone, yesterday. Still getting these codes. Fuel cap isn't the issue, already ruled it out. Now my RPM's are higher than before, when I am warming the car up and when I put it into gear. No issues with filling it up or starting. One thing that did change was I got a transmission code back when I started having issues with the EVAP system. Now I am just getting EVAP codes and not getting that transmission code. This is indeed a strange situation and I am frustrated!
Have a 2023 civic 1.8L. Had a p0145c and p0497. I replaced the purge solenoid with import direct part. Problem went away. Came back 2 weeks later. Warrantied the part, codes still wouldn't clear. Bought the Honda OEM purge valve. Problem went away but came back 3 hours later. Checked evap canister for blockage, but ait was flow through it just fine. Replaced the fuel pressure sensor and gas cap. Then pulled vent solenoid on canister and tested for stroke and seal. Was good. Codes still there. Honda purge valve is working, and I can hear it thump/ticking. I monitored fuel pressure with scan tool and saw it fluctuating between 0inwc and -0.4inwc. The -0.4inwc seems low so I'm thinking a collapsed hose or an obstruction somewhere in the hoses or air intake.
@AutoRepairTips757 yeah. I did a smoke test on it yesterday. No leaks, smoke gets to everywhere it should. No obstructions to vapor/air flow. Have put 100+ miles on it with 30+ starts. Codes won't clear. Can clear the codes with scan tool, but they just come back. I'm imagining that there is probably a relearn procedure that I am unaware of.
@AutoRepairTips757 going to do a relearn by clearing codes and driving down the highway at 55mph and the coasting down to a stop several times. Only thing I can think of at this point.
Hello i have the same code on my 2011 chevy traverse.. had the purge value replaced twice. But the check engine light always comes back on. When i pump gas my truck won't start. I've been told it could be my charcoal canister
Same with my 11 Acadia. I've changed it 3 times. That isn't it. I just changed the cap and I hope it helps. Did you figure anything out? Now I'm getting p0420 as well
Yeah and small vibration in the steering wheel and worse gas mileage. That's what it did to mine. Acceleration was boggy too, and once it was the air fuel ratio oxygen sensor..for those acceleration issues.
Pushing that scv back in was the hardest part, that oring was so thick, that it refused to go in
I replace everything even the charcoal canister same code car still running on limp mode probably have to get a new Cat converter is what I'm guessing 🤦🏽♂️
My 06 civic gas cap readings came up on the dash and I replaced the cap and it didn't go off it been awhile now

I had both the fuel cap light (it was not tightened all the way) and the P0497 Code.

Did the solenoid swap help the car start?

I hate those kind of jobs

Have you figure something out? My car has same issue
Same here
I've also heard that after this replacement that you need to recalibrate the system but I doubt that
What do you mean ?
The computer does that on its own.
Can this also make rattling,ticking sound? Also could this code also cause the low pressure oil to pop up and go off?
not low oil psi
What name of part I have Honda civic 2012
Hello I like your video but I do have a question, I did replace the part but then code came back ? ??? What kind of noise do you mean ?
Can you email me what noise your hearing?
Excellent video

How do u test the solenoid
there is a site online that shows you ill try to find it. i use a scope
Thank you buddy
Do you recommend putting any type of lubricant/grease on the oring when replacing the valve? If so what are your recommendations, thank you!
I like to use dielectric grease
Thanks, bro 😀
Would this cause poor acceleration?
Yeah and small vibration in the steering wheel and worse gas mileage. That's what it did to mine. Acceleration was boggy too, and once it was the air fuel ratio oxygen sensor..for those acceleration issues.
typically it can also be the gas cap
