Is your gas cap screwed on TIGHT? Failure to build a very slight,
measureable vacuum in the tank while driving can set off this code.

HELP With Trouble Code P0440
Hope someone can help me out here.
My vehicles 'Engine' light came on yesterday and a friend of mine hooked up
his Diagnostic Scanning Tool and checked for Trouble Codes. There was one
Trouble Code and it is listed below:
ERROR Code P0440
"Evaporative Emmission Control System Incorrect Purge Flow"
Can someone pls explain what this means and wheter this code is the reason
the 'Engine' light came on?
What do I need to do in regards to this situation.
The car in question is a 2002 Toyota Corrola
Thank you for any response
Winston

Yes this code will cause the check engine light to come on. In fact
it's the number one cause of check engine lights coming on. Most
common cause is a loose or non-factory gascap. Make sure the cap is
OEM and tight, disconnect the battery for a minute or two to clear the
code. If the light comes back on with the same code the evap system
needs to be checked for integrity and all the control valves checked
for normal operation. Best take it to a dealer for diagnosis, it's a
complicated process.

Instead of disconnecting the battery, is there no longer a single
fuse you could pull (like the BRAKE light fuse) to accomplish the
same memory clearing?

Re: HELP With Trouble Code P0440
Winston,
As Steve said it is a complicated process to check out the EVAP system but
it can be done and at a substantial cost savings if you are so inclined. I
have a 2000 Corolla and just had an EVAP system problem that set off codes
0440, 0441 and 0446. As several people have pointed out the gas cap is the
first culprit. Please note that the 2000-2003 1.8L Corolla engines have
been known to have the fuel pressure sensing switch on the EVAP charcoal
canister go bad. This is what happened to me. If after trying the gas cap
the light comes back on let me know and I will help you out with the
troubleshooting and or replacement of the various sensors on the system.
For piece of mind the switch that went bad for me was $60 via internet mail
order and about 2 hours labor on my part as compared to a $300 dealer
repair.
Good luck,
Scott
