2015 malibu

I have 2 69 Chevelles but my son has a 2015 Malibu, I'm looking for info on how to replace the vapor canister vent valve solenoid. I'm not sure it is where located. Under the hood or by the gas tank. Any info is greatly appreciated. Glad my cars are older,much easier to work on. Thanks guys

Re: 2015 malibu

I had the same B>>>>S>>>> with my 010 6.2 Silverado. One was located at the Alt. on the engine the other was on the frame rail about half way back to the rear.
The little one was around $30.00 the bigger one on the frame rail was around $60/70.00
Both of my 70s have the same thing. BUT... The chevelles have a solid steel line from the tank to the engine, NO B.S. wiring or controlled by a Computer. Just more stupid $h!t to spend money on! Bottom line is: It takes the fumes from the tank to the engine........... DAAAAaaaaa !

Tom,
When you go to the dealer to get the part ask them if they can pull up a diagram showing where it is at ??

Re: 2015 malibu

what is the code you got from the data link.... most of the time 2015 Malibu
pop out a P0496 P0496 CHEVROLET - Evaporative Emission System Flow During Non-Purge

Possible causes
Faulty EVAP Canister Vent Valve
Faulty EVAP Canister Purge valve
Plugged EVAP canister condition
Faulty EVAP Pressure Sensor
EVAP Canister Vent Valve harness is open or shorted
EVAP Canister Vent Valve circuit poor electrical connection

MY 1st choice is always evap canister purge valve under hood easy fix
what you are talking about is under car near gas tank ....

thanks for the info i'm not sure of the code because my son had it checked and this is what they told him the code called for. I'm definitely going to try the easier one first. Thanks

Re: 2015 malibu

May or may not be related but topping off tanks will cause the canister to go bad, had that happen on my Vibe.

That is a "small" evap system leak. Could be anything. Make sure the gas cap is tight.



I would see if there is a good shop near him that can smoke test the system rather than throwing parts at it.

Re: update 2015 malibu

DTC Descriptor
DTC P0442
Evaporative Emission (EVAP) System Small Leak Detected

small leak could be gas cap ??? start with gas cap

Diagnostic Aids
The EVAP system can be filled with smoke more quickly and completely by opening the system opposite the end where the smoke is injected. When injecting smoke at the service port tool temporarily leave the EVAP Vent Solenoid Valve open until smoke is observed then close the system and continue testing.
To help locate intermittent leaks using the GE 41413-A, move all EVAP components while observing smoke with the GE 41413-SPT.
Individual components can be isolated and tested using adapters in the GE 41413-300.
When servicing the EVAP system, test pressure must not exceed 13 in H20 (0.5 PSI) as pressure in excess of this could cause system components to perform inaccurately.
A condition may exist where a leak in the EVAP system only exists under a vacuum condition. This type of leak may be detected by using the scan tool Purge/Seal function to create a vacuum in the EVAP system and then observe the FTP Sensor parameter for vacuum decay.
info comes from alldata pro if you change cap tune light off drive it for 3 days them check codes again hard codes and pending...ECM will check for leaks at cold start up.
