Recently, three lights came on in my car: VSC, Trac Off, Engine Check
They came on the day after I took my car in for oil change.

I finally found time to take it to Auto Zone & these are the trouble codes it came up with:

P0441
P0442
P0446

Can anyone tell me what they are? Is it gonna cost me an arm & a leg to fix?

Thanks!!!

 

P0441: EVAP Control System Improper Purge Flow
P0446: EVAP Control System Vent Control
P0442: EVAP Emissions Control System Small Leak

Check gas cap to see that it is on tight and go from there. Could also be a number of other things -- bad vaccum switching valve, cracked charcoal cannister, etc.

Tighten gas cap, reset codes, cross fingers.

 

I have pumped gas since the lights came on....
how do i reset the codes? thanks

 

If they did an oil change they probably checked the air filter. There is a vacuum switching valve on the left of the top of the air box. Usually the hse will pop of when you check the filter. Check all hose connections around the air box & reconnect appropriately. Take it back to the dealer, tell them the hose was off & ask them to clear the light, at no charge obviously.

 

ok will try that...thanks! i took it back the day after, they made me get an appointment

 

Are you an '06? Smells like the good ol reliable EVAP TSB.
