EVAP Trouble Codes P145C and P0497 - Honda CRV

How To Repair EVAP Trouble Codes P145C and P0497 In A 2009 Honda CRV
Now this is not the end all cure all. There is many things that can set this code. For example a faulty FTP sensor, A faulty CCV, a plugged vacuum line just to name a few. This video is only showing what happened to this car. Hope it helps and please don't forget to subscribe.

[@gregnixon1296]

Thanks for the video. I just replaced mine in a 2009 Pilot, $70 for the part. Took about 30 minutes. Most of that time was spent trying to get one screw loose. As a bonus, I found a "lost" tool under the hood. Winning day all the way around.

[@elNenio]

straight forward and precise! none of the other bullshit.. thanks for the helping regular people and fellow mechanics like i am. :D

[@darrellreich653]

Bro, just must say that you explain stuff perfectly and are awesome.

[@Apulux]

i change this maybe 2 months ago and now its back? is it something else ?

[@larryh8072]

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...

[@jnbyoung]

I have the same symptoms. It was not showing a code when I went to the dealer. Check engine light came on today and using my scanner now it shows these two codes. I think I finally have my definite answer! Honda wanted $150 to diagnose and I'm glad I did not go that route.

[@plekplek4934]

I replaced the purge valve on a V6 accord 7th gen. Code gone and returned again. A mechanic told me it might be the Vent valve next to the charcoal canister.

[@DrWenChannel]

Thanks! So it looks like it's the "purge valve" (Honda part#: 36162-RRA-A01) that need to be replaced, right? Can we assume that based on your experience, >90% of chances it's that purge valve that need to be replaced (when getting the EVAP Trouble Codes P145C and P0497)? Also, is "overfilling gas" the main root cause of these "purge valve" would fail prematurely? Thanks!

[@johnbarrett3170]

2009 Honda accord 2.4l JUST Passed This Test Initially smoke test revealed CANNISTER and FILLER TUBE Leak. Canister with vent valve, all rubber molded hoses, Gas Cap and Filler Tube were replaced. it lasted 6 months. came back p0497-p145C. Noted the vacuum line from purge to intake was loses trimmed back secured. Conducted vacuum test with bi-directional, passed: 25- 0 mercury quickly. I'm told from Honda tech use Honda purge valve, or the electronics will fail and generate the code. any thoughts before I conduct smoke test 2?

[@rogershipley9970]

That didn’t fix my 2011 Honda CR-V I’ve changed the the cap purge valve and the pressure sensor what’s next?

[@Susan70003]

What was your resolution?

[@maxammo6282]

I replace the solenoid I'm still getting a check engine light. I put a new fuel cap on it. My question is what would be the next logical step? Would it be the canister shutoff valve?

[@glengarbera7367]

Did you ever figure out problem with evap solenoid?

[@maxammo6282]

@@glengarbera7367 yep I bought a Ford. The car was on its last leg anyway. The moral of the story is do not top off your tank if you're filling up your vehicle and it shuts off do not put any more fuel in it. That's what caused the problem. I'm old school I'm not used to all this new BS on these vehicles. You keep topping off your fuel tank in these newer cars with these canister evaporators. You will run into the same problem. Again once that pop shuts off when you're filling it up do not put any more gas and spread the word. Let your family and friends know. You're not going to go that much further with an extra 50/60 in the gas tank. But it will cost you dearly if you keep doing it trust me.

[@bbqsmokernc7252]

Would i get a tighten gas cap message with this also? 2011 Honda Pilot... I have both the codes.

[@ColonelK0rn1]

Yes

Hey man thanks for your video, so when you change the VALVE ASSEMBLY, PURGE CONTROL SOLENOID is that going to clear both code Trouble Codes P145C and P0497.

[@denisgonzalezblandon1538]

mine ended up being the canister vent valve, canister had water inside and solenoid was not clicking from the water damage, cleaned out the water and passed inspection

[@anti0918]

Replacing the EVAP purge control valve / solenoid fixed the problem on our 2009 CRV with the same error codes plus Check Fuel Cap. The part number: 36162-RRA-A01.

[@boglin80]

brian0918 what’s an ideal cost for having that replaced?

[@BobSnyderAuto]

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+

Replaced mine on 2011 Honda Pilot and problem solved. I also had fuel cap error which disappeared. Thanks

[@kkokoruz]

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?

[@HarborLockRoad]

My 08 accent has this code, changed gas cap w factory one, new purge valves f & r, smoke tested, all hoses good, gas tank n charcoal canister look good...but the light keeps coming on every cycle. Ive already been taken for $400.00

[@jameslacy8331]

Same here. New purge valve, Front & rear, new EGR, I guess I'll drop the canister in the back. I don't care about the emissions code but I got stuck in a ditch because my AWD is disabled by codes. Any luck yet ?

How much did that job you did cost?

[@SouthMainAuto]

I'd have to look it up it was a while ago... Don't really recall. Just what ever the EVAP solenoid costs plus a little labor to diagnose.

[@twochillywolf]

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.

[@charlesberkeley6429]

TLDR; if you get an emissions system issue on your Honda your cheapest and easiest fix is going to be to replace your gas cap with an OEM Honda gas cap. Change your gas cap. That's the first thing a diagnostic chart is going to recommend that a mechanic do. Here's a story that might help some of you. I replaced the gas cap on my 2012 Civic from the OEM gas cap to a NAPA generic cap a year ago. A code came up, I went to NAPA and the scan tool diagnosed that as the problem. I changed the OEM Honda gas cap with a $15 NAPA gas cap. Here's the kicker: A year later (today) an emissions system code came on with a check engine light. I suspected it might be the gas cap again because sometimes replacement parts trip the sensors in the evap system. So, I went to Pep Boys and had them run a scan tool on it. P0497 and P145C codes came up. That's low purge flow (P0497) and P145C is a generic, catch-all emissions issue code. I told the guy there what happened and that I suspected it was the replacement gas cap. He suggested I bring it back to Pep Boys where they'd charge me $110 for diagnostics and additional charges 'if' it needed a smoke test. It felt like BS. So, I went to Honda and bit the bullet for the $78 OEM gas cap. Came back, replaced it (kind of a pain because it is tethered but finally got it) and disconnected the negative terminal of the battery to reset the computer. Reconnected the battery, crossed my fingers, and started the car. Guess what? All clear! I'm pumped.

[@roadtoexcess]

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!

[@danielsimpson8929]

A friend just came by and these are the codes we pulled. Did the cap o'ring grease and cleared codes. Looked under the hood found what I thought was the solenoid and tapped it. Started and no cel. Looked the codes up anyway as I figured solenoid is on the way out. 80% of my understanding of cars is KZbin based, and of that Eric you make up for atleast 50% of that 80 which is to say as much as I can considering I'm a junkie for auto repair and channels like RnW, Automatic Transmission, speedkar99, tacomoto, rusty beauties, gearboxvideo, Mighty car mods, and many others I'm forgetting. Hit the jackpot again that you broke down this quick diagnosis, confirmed what I was tapping on to be the solenoid, and that I could jumper to test function with suction (only have a basic obd2 linkmx bluetooth reader). You've repeatedly given freely valuable information and help with your viewers confidence as we would otherwise fumble through it for 4x as long or longer to do it on our own. So thanks for that!

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.

[@aidennico08]

I don't have a professional scanner like he does I"ll have to check vacuum manually so when he says jump power ground across...what does he mean?

[@ColonelK0rn1]

You can use a 12V power supply (battery) to test the valve and see if it is functioning correctly. Unplug the harness connector from the valve, and use a jumper wire to apply 12V to the valve, doesn't matter which terminal on the valve you apply + or - to. Just apply voltage to the valve, not your harness, otherwise you will more than likely damage your PCM. Once you have power and vacuum applied, replicate the tapping that he does, and see if you get the same results. The scanner just utilizes the connections and the PCM to do the same as an outside voltage source without disconnecting the harness from the valve. This would also help diagnose if there was an issue with the wiring since the signal is coming from the computer commanding the valve to close since it's state is normally open. If the valve didn't close, and the scanner is showing the duty cycle to be near 100% then there might be a broken wire or faulty connection to the valve.
