Question about 2003 Chevrolet Cavalier
The code is pretty standard and has to do with emissions. Manufacturers these days have strict rules to emissions that the car puts out. So, this code relates to that.
It is Evaporative Emission Control System Malfunction
A code P0440 could mean one or more of the following has happened:
P0440 EVAP System No Flow During Purge Possible Causes Setting Conditions
I would disconnect battery for 1 minute, and reconnect and see if the warning light comes back on.
Just remember you might lose your radio code if you do this.
Let me know how it goes...
