I would start with the basics depending on which code(s). Is it a small leak, medium leak or large leak? It may be related to the fuel cap or how it seals. It may have a leak or part failure within the evap system. If the cap doesn't solve it, find the local snap on tool dealer and ask him the best troubleshooting gargage for this in your area. He should know. This really isn't a d-i-y kind of thing for most.

How long does the warranty on catalytic converter last on a 2003 Toyota corolla?

The emissions warranty on the 2003 Corolla is for 70000 miles. I have recently had the check engine light come on and had the dealership analyze the issue. They pointed to the catalytic converter. The check engine light came on shortly after the car reached 75000 miles. Bad new is the dealership quoted repairs at over $1200! Needless to say, I was not happy with the diagnosis nor the price. I expect better from Toyota products.

How to change timing belt on 1999 Toyota corolla?

there is none. fortunately you have a timing chain on your car (I also have a '99) and it lasts forever. well, almost forever. I had one on a Toyota pick-up, 1980s vintage. eventually it came through the timing chain cover -- but never broke. it had over 200,000 mies on it at that point. something else killed the tuck, not the timing chain.

1990 Toyota corolla rr power window went down - will not come back up using frontrear buttons Toyota service said they could prop it up with a 2x4 but that it would problably come smashing down?

the window motor is bad. order a motor . then have it replaced. easy to do your self. former Toyota tech.I would try replacing the switch that controls the problem window first. I had the same problem with the front passenger window of a 1999 Corolla. I thought it was the motor at first but when i put the switch from the rear window on it, it came up just fine. I don't know why, but it also effects the driver's control panel.

How long will it last when a Toyota Corolla engine's fuel light lights up?

not sure about newer models, but I used to own a '98 Corolla, and when the fuel light came on I had approximately 30 miles before I would run out of gas, so unless they've increased it, I'd say it's probably safe to assume it's about the same.

How do you add refrigerant on Toyota Corolla where is the intake point for the r134 on Toyota Corolla?

In my 1996 Corolla, the intake point is in the back left corner when you open the hood. It's a small cap about half an inch wide and an inch long, has an "L" on the top and when you remove it and look at the inside it should be light green. My can of r134 came with a blue hose with a pressure gauge attached to it and you just unscrew the cap on your hose, attach the hose with the r134, and hold the can of r134 upside down while shaking it. The engine should be on with the AC on at max while you're doing this for it to charge properly. Hope this helps.
