CEL comes on today!!!!!

[cumminspuller]

My wife calls me at work today, stating her CEL came on. This is a 2002 Camry SE with 74K miles. Just took the car to Autozone and the codes are p0440, p0441 & p0446. I kind of looked around on here and did not see anyone with all three of those codes. Could have missed it though. I have already tightened the fuel cap, but have not disconnected the battery. Could this just be a VSV problem? Or is there anyway to narrow this down a bit farther? Any help would be greatly appreciated.

Thank you,

Jason

Cumminspuller,

Did you try looking on http://www.obd-codes.com/?

If you do a search with all three codes, you'll pull up tons of results.

Indicative of a large leak, usually either the gas cap or loose vacuum hose.

Thank you Qslim.......I will do some more digging today.

Look at the cap again, closely. Did you fill up before the CEL went on?

It's not called a CEL. It's an MIL.

Check Engine Light, Malfunction Indicator Lamp, Same difference.

Now TRD will learn something...

Actually, I already knew. That's why I stated what I did. Now maybe, you'll learn something besides trolling after me today...
