You need to know what the codes me first. If you go to an auto parts store they will hook it up to a computer and tell you what the codes are.

1998 toyota camry, 2.2L 4 cyl. P0325, P0441 and P0446 trouble codes


Code 325 is for a problem with the knock sensor circuit, code 441 is for an incorrect flow with the purge valve and the vent for the gas tank, and code 446 is also for the vent control circuit.
I would clear the codes and see how many come back after a test drive. You may need a shop manual to test the circuits.

According to my 2002 Toyota Tundra manual (and it may be different for your car) P0125 is as follows:
Insufficient Coolant Temperature
for Closed Loop Fuel Control

This would seem unrelated to your original problem.

On a 2003 Toyota Corolla, does the fuel injection system need to be cleaned?


Unless there is an obvious problem No! What you can do is go to any automotive supply store and get any kind of fuel injector cleaner that pours into your gas tank. You could do it one a month or whatever you feel is necessary.

Code 441 and 446, also poor performance, corolla 2006


You have a OBD, you have the code defined and now you want the opinion of an unknown person with unknown skills at some unknown location, to you, upon which you will base a decision to spend or not to spend? I don't understand your motivation.

Pleae make sure you review the Terms of Use of this site.

While I appreciate your interest in FixYa.com, you already have an answer to your question. Why are you here?

Hello! Those three codes commonly indicate the followi possibilities:

The gas cap was not sufficiently tightenend ater fueling, a bad gas-cap rubber o-ring, the vehicle had the key in the 'on', or engine running, or the tank was filed all of the way up the neck.

Any one of the abope causes will set all three codes.

Engine light keeps coming on


The P-0440, P-0441 and P-0446 indicates that you have a leak in the "fume" side of the system. Normally, seeing a 440-441-446 is a loose or defective fuel cap. One would NOT change the evap VSV for a 440-441-446 set of codes. At this point, I agree with you regarding the trust issue. Regarding the caisiter, I cannot speculate yes or no, without further info/codes/etc from your dealer, but, I have replaced several over the past few years; this "could" be true....
