Hey, Im back from auto zone and getting the codes, the code on the computer is P1457
Expert:  Amedee replied 10 months ago.

Thank you for getting that code for me. This is usually caused by a Evaporative Canister Vent Shut Valve. Was this replaced?

Customer: replied 10 months ago.
We ordered one to replace but it won't get here until tomorrow, will the "check engine" light go off if we replace it and it was the problem??
Expert:  Amedee replied 10 months ago.

Eventually, yes, the check engine light will go off by itself if that is the problem. This is the most common cause for this code. However, any leaking component in the EVAP system can cause this code. Here is the definition for this code.

P1457 EVAP System Leak Detected (Canister Area)

Possible Causes

EVAP two-way valve or ORVR vent shut valve is damaged

EVAP canister purge line is loose, damaged or blocked

EVAP canister is leaking, damaged or full of water

EVAP fuel tank vapor control valve has failed

PCM has failed

Customer: replied 10 months ago.
We changed the evap two way valve, reset the light yesterday and the check engine light came on today again, any input on next step??
Expert:  Amedee replied 10 months ago.

Your next step is to get the evap system smoked checked for leaks with a smoke machine.

Customer: replied 10 months ago.
Where do they do the smoke check??
Customer: replied 10 months ago.
Where do they do the smoke check at???
Expert:  Amedee replied 10 months ago.

They can go through the fuel filler neck or there is a evap smoke port under the hood that can be used to smoke check the evap system.

Do the autoparts store sells canisters of smoke to inject on the system??

Auto parts stores might have to smoke machine. If not I'm sure you can get it on line like Amazon.com
