2003 Toyota Matrix Cat Converter Replacement Sign In

Hello. I have a 2003 Toyota Matrix XR. I'm in Illinois and (long story short) I need to get passed on the emission test in the next seven days. My local mechanic has stated that I need a new Catalytic Converter and Oxygen Censor. He's quoted me at:

$685.07 for Catalytic Converter and necessary gaskets
$125 for Oxygen Sensor that's in the converter
$157.50 for labor
$1038.45 total

I spoke to a friend of mine and he thinks this is too much. To make add to the fact that I don't want to pay that much, I plan to get a new car in the next year or year and a half so I don't want to throw $1000 into it. My friend recommended me to a mechanic who'll let me bring in my own parts and they'll do the work, obviously a much cheaper option.

Here's the question. What parts do I need to get? I've done lots of searches for catalytic converters and oxygen censors for my car but I see so many options with additional accessories that I'm at a lost.

Any help would be most appreciated! Thanks.

That is one reason to reconsider your choices here. There are prices to be paid for taking the route you are taking. You are giving up all warranty on your repair. The installer is not going to have any responsibility for the parts or labor. You really aren't going to save enough to justify the problems you can encounter by trying to do this.

I don't feel like paying the dentist either but that doesn't mean I won't have to anyway.

Toyota's emission warranty is 96 months or 8 years.

There is also a TSB (technical service bulletin) out for P0420 setting. The PCM has to be reflashed and converter replaced.

I don't know if your mechanic has seen this TSB, but replacing just the converter without doing the reflash, if applicable, might not solve your problem.


TSB EG026-04

Re: 2003 Toyota Matrix Cat Converter Replacement Sign In

[UPDATE] Thanks for your replies. You helped me make a decision.

I should have mentioned that I bought the car in the Spring of 2003. It was made in May 2002. It has about 150K miles on it. So warranties are a no go.

So, today I went to the mechanic and told him that I just wanted the oxygen censor replaced. He pretty much flat out told me "no" and said that it was the converter. He showed me the replacement converter and showed me where the oxygen censor was. He said that the sensor was AFTER the converter (apparently, there's also a censor before the converter, but that's not the problem one). He said the code says it's the converter and not the censor.

From there I went to an Autozone and got my codes read. The only code that came up was P0420, which I'm told is a general code for the converter. Even the Autozone guy said that he's leaning more towards the converter than the oxygen censor. He said a different code would come up, or multiple codes, if it was specifically the censor. Autozone then gave me the pricing for what I needed; the total price, with gaskets, the oxygen censor, and the converter was $490. I decided to buy them because it was far cheaper than the $810.07 that my mechanic was offering.

Here's the kicker. I called my mechanic back and asked him if I could bring him my own parts and have him do the labor and he no. I thought this was strange as I've never heard of a mechanic saying no to a person bringing in their own parts. So as of right now, I trying to find a mechanic who'll do the work for a reasonable price.

Thanks again for all your help.

A defective oxygen sensor can't set that code. You need a converter and a reprogramming of the computer.

Most reputable shops wont install customer supplied parts

All places i've worked never did.

Might try to find a mechanic that does side work to do it.

It isn't going to help him in this case because he needs the computer reflashed.

A reputable shop is like any other business. They make money off of parts and labor. They buy a part at one price and sell it at a higher price. The markup is their profit margin. If a customer was to supply their own part, that would be cutting out a good chunk of profit for that business and this is why a lot of shops won't install customer supplied parts. Not to mention other reasons such as warranty, that Desi already brought up. All is well & good when everything goes as planned but if the part is defective that is when the problems surface. Since the customer took the role of the "parts house" he/she assumes ALL the responsibilities that go with that. Warranty labor for defective parts is one of them. The partshouse (customer) would take the hit for that not the shop...... Its more common in the automotive field but would would be the same thing as taking a steak into your favortive restaurant and asking them to cook it for you so you can get a cheaper meal.....
