Check Engine Light Due to EVAP System Fault on Toyota Matrix

Problem Description and Possible Solution

The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.

My check engine light came on and I took it to my dealership. They sent me a photo of a hole in one of the hoses coming from (or leading to) the gas tank. They told me this hole triggered the check engine light. They also said that the hose cannot be replaced alone, and that I must purchase an entire gas tank to fix the problem. I wonder if it's possible to patch or replace the hose, despite what they have told me.
Whenever I would gas up, the light would come on and stay on for the first half of the tank..then go off.
I failed an inspection because of it.

I paid more than $400 to two garages and never got the problem fixed...finally registered the car in Florida and I don't need an inspection.
i dont know if its the evap system however my car trys to stall and looses power for a couple of seconds..after that..runs great
I have an evap code.and a strong smell of gas from time to time and even a leak from the top side of the tank when filled all the way. I can seem to find where it is coming from though.
Codes 441, 420, &446. I don't smell gas, I have pinpointed it to the charcoal canister, after taking it to toyota for a diagnostic and wasting my money I took it apart and figured it out myself. My mechanic tested the gas cap, it was fine.
check engine light came on; Toyota replaced the gas cap and then told me the 'sleeve' from the cap to the gas tank needed to be replaced ($1200); they said it is a problem with 2004 Matrix's but since I had the repair in 2010 I was out of warranty##**!
Light came on to check engine. Was told it could be a problem when testing for emissions. Estimate of approximately 700.00. Is this a recall issue?
I have very upset. I have a 2006 Toyota Matrix. I had to take it in for repair/examination due to check engine light. Keep in mind I had to take it in to Toyota dealer several years back on a recall matter and the check engine light was on at that time. The codes with regards to the check engine light are as follows: P0741-torque converter solenoid likned to transmission and also P0171-system to lean bank one code. I was told when I took it to a Toyota dealer with online documentation with regards to both codes that they could not take care of it. I am not dealing with a shop and of course they want an arm and a leg in terms of payment. The shop gave me 3 different fees amounts $1100, 1600, 1400. If I merely just replace the torque converter that will cost $1100.00 and the paperwork stated, "this is possibly the problem," that is after a fee of $120.00 to per their add properly diagnoise the transmission problem. At this point I had to get my boyfriend involved. The conversation ended with me having to go with a rebuilt transmission becaues the transmission "may" go out not will. I point all fingers back at Toyota. There is a host of complaints online about transmission problems with no prior notification being given to customers. From this bad experience I will say 100% for sure I will never buy a Toyota again. Its sad they have a host of these problems online yet they wont own up as a business.
