Check Engine Trouble Code P0496: How to Diagnose GM EVAP Problems

[@muneymap]

So what does high purge flow mean?

[@lukesexton2152]

Excellent and simple. Thanks so much.

[@757MrMark]

Besides mentioning the code, what operational things might be happening?

[@RockNRollMan1976]

Have this problem with my 2011 silverado, replaced the solenoid twice, still gives me the same error.

[@samanthacooper6776]

Can a bad purge valve also cause a lean code?

[@mckoylach1622]

Thanks for sharing your videos

[@kmart014]

Will this cause the catalyst monitors to not be ready at smog check ?

[@thuff86]

Changed purge valve solenoid on 2011 colorado. Code on still. Also changed gas cap, etc.. Haven't changed vent valve, is that possibly the cause? P0496

I changed mine with brand new one but the code won’t get cleared after , it’s day permanent . I tested the new one and it’s work properly but the code don’t want to go away .

[@nataliewhite4772]

I’m having the same problem. Did you ever figure out what was causing the code not to clear?

[@StLMikie]

Did you replace your gas cap and or check the hoses going to the solenoid for cracks or breaks?

Either I’m an idiot or something is awfully coincidental. This is the same code for a Ford for the same thing🤔
