Anyone dealing with EVAP purge valve issues in a 2019 Chevy Traverse?

Questions and Support
1

I’ve been having some trouble with my 2019 Chevy Traverse, specifically related to the EVAP purge valve. I’ve noticed the check engine light coming on and after doing some research, I think it might be related to error code P0496.

What I’ve Noticed:

  • Check Engine Light: It turns on intermittently, and the code reader points to P0496.
  • Fuel Efficiency: I’ve been getting worse mileage lately.
  • Strong Gas Smell: Particularly after refueling.

Questions:

  1. Has anyone experienced similar issues? What were your symptoms?
  2. Is replacing the EVAP purge valve an easy DIY task? Any tips for a first-timer?
  3. Can a faulty valve cause long-term damage? Should I address this immediately?

I’d appreciate any insights or guidance on this. Thank you!

I had a similar issue with my 2019 Chevy Traverse. The check engine light came on, and I noticed a drop in fuel economy. It turned out to be the EVAP purge valve. Definitely check for those symptoms!

I’m dealing with this too! I also noticed rough idling at times. Could that be related to the purge valve issues?

4

Yes, rough idling can definitely be a symptom. The EVAP purge valve regulates the flow of fuel vapors, and if it’s malfunctioning, it can throw off the engine’s performance. It’s worth investigating!

I’ve also noticed a hissing sound when the engine is off. Is that common when there is an issue with the purge valve?

Totally common! A hissing sound can indicate a vacuum leak, often linked to a malfunctioning EVAP system. It’s an annoying sound for sure. Get it checked out sooner rather than later!

Is there a way to test the EVAP purge valve before replacing it? Don’t want to throw money at it if something else could be the problem!

You can use a multimeter to check the valve’s resistance. If it’s out of spec, it’s likely faulty. Always good to confirm before replacing anything!

Thanks for the tip! How do you find the specs? Is it in the repair manual?

10

Yes, the repair manual typically has those details. If you don’t have one, online forums and auto parts websites may have that info too. Good luck!

I love how these posts really help one another. Makes me wish automotive repairs were as simple as baking a cake! Just measure and pour, right?

Ha! If only it were that easy! But I appreciate the humor amidst the frustration.

Reflecting on this, if anyone finds a straightforward solution to these issues, the Traverse community would surely benefit! I’m hoping for a quick resolution.

I’ve had issues with the EVAP purge valve on my Traverse too! I DIY’ed it and it was pretty straightforward if you’re handy. Just a few tools needed. But I can see how some would prefer a mechanic to avoid headaches.

That’s great to hear! What tools did you need? I’m torn if I should do it myself or head to a shop.

Replacing it was not too bad! You’ll need a socket wrench set, maybe a pair of pliers, and some patience. But if you’re not comfortable, a mechanic’s help can save you time.

17

That sounds doable! But I wonder if there’s a cost difference? How much did you pay or would a shop charge?

18

A dealer might charge upwards of $200 to $300, while you can find the valve for about $50-$100 online. DIY could save you a lot!

19

Wow, that’s a big difference! I guess it boils down to how much time I want to spend on it.

Exactly! Plus, it can be a bit of a learning experience if you do it yourself. But be ready; it can get messy!
