Replying to: azmustang (Mar 25, 2009 8:29 pm) Wow what a Catalytic problem.   First, air sensors should be easy to change, and about $25.00 dollars each. You're check light is coming on? I would not get to concerned about the light. It could be improper installation on the rear converter.   Not much could go wrong here though. I would get an Emissions test to check for exhaust pollution levels. I think converters reduce NOX's gases.Then go from there.This is only the exhaust and dosn't effect the engine at all only the atmosphere. Replies to this message: toptech (Apr 11, 2009 10:45 am)
#31 of 72 Yet another check engine light question by bryanbbfan Mar 30, 2009 (9:50 pm)
I too have a check engine light question. I just purchased a used 1997 Toyota Camry from a private party. The condition of purchase was that the seller would get a current California smog certificate and replace the plug wires before I would buy it. So the next day, the seller had a completed smog certificate from that day and new plug wires under the hood. I completed the purchase. About six miles out the door, the check engine light comes on. I have in my hand a legitimate smog inspection report stating that the car passed date today, and there are brand new plug wires under the hood.   My question is: Is there something either the smog check or tune up technician could have done, or forgot to do, to make the check engine light come on? Is there some sort of code that was supposed to be reset and possibly forgotten?   It is difficult to believe that there some failure so soon after a passed smog check.   Thanks
#32 of 72 warranty on exhaust system (front) / Catalytic Converter by wenhq Apr 05, 2009 (7:14 am)
Could anyone help me on this?   I bought a used 2001 Camry CE in year 2005. I had no idea about the separate emission warranty until now. I failed my state inspection in MA last year (Setp. 2008, around 70K miles) for the bad catalytic converter. However, i never got the check engineer on. I went to Toyota dealer and replaced the catalytic converter, which costed me $1300. I remembered that i asked the service manager if this is under warranty, and he said no.   Now (7 months later), I realized there is a emission warranty, which is for 8 yrs / 80K miles. Could anyone confirm this for me since i don't have the owner's warranty booklet? I just checked my repair receipt last night, and it stated as Exhaust System (Front). It didn't say Catalytic Converter. Is the Exhaust System (Front) same as Catalytic Converter.   Tomorrow, I am going to the dealer and ask for the money back. Is there any chance I can get my money back since the catalytic converter is under warranty?   Thanks and any inputs are appreciated.

Replying to: rearwheeldrive (Mar 27, 2009 1:54 pm) 25 Dollars for an air fuel ratio sensor? lol some people are not even on this planet. And it only has one if it is california emission. It has afr in the front and ho2s in the rear.

Replying to: azmustang (Mar 25, 2009 8:29 pm) There is no good way to determine wich one is causing the light to come due to how they are tested is by looking at the rear o2 sensor and that sensor is monitoring both converters! But from experience aftermarket converters on these cars DO NOT WORK OR WORK FOR A VERY VERY SHORT TIME AND ARE A WASTE OF MONEY.Amazing how many garages have no clue and waste hard working peoples money. Take it back to the guy that put the aftermarket cat and let him fix it the rite way. Replies to this message: rearwheeldrive (Apr 13, 2009 9:53 am)

Replying to: toptech (Apr 11, 2009 10:52 am) I replaced mine just for laughs. $31.99 Autozone. 1987 Corolla. 4 cyl.     The new models have gone up. Does anyone go to junk yards? You can find cheaper prices and sometimes you get lucky and find a new part. A sensor should be easy to remove, (search blog 1990 Q-45, a trip to the junkyard). Although converters are sold for scrap and missing most of the time.
#36 of 72 2003 camery le check engine light/catalytic converter by cbayhoo Apr 19, 2009 (9:59 am)
The check engine light came on about 600 miles into an 850 mile trip. Everything was OK and had it checked at dealer upon arrival. $101 for diagnosis and $767 estimate for new cat converter (code p0204). Let me chew on that!! My son called his trusted mechanic and was told $300 total. Then called my mechanic at home---he said drive it! I'm home in VA and light is still on but car runs OK. So, what's next? State inspection is in Sept. Replies to this message: toptech (Apr 22, 2009 3:54 pm) wwest (Apr 23, 2009 7:58 am) toptech (Apr 23, 2009 2:11 pm) and 4 more... cbayhoo (Apr 28, 2009 6:22 pm)

Replying to: cbayhoo (Apr 19, 2009 9:59 am) U can drive it with no problems. But u may not get a sticker depending on or states emissions testing. Lol that suposid trusted mechanic is gona cost u alot more money in the long run. He is stupidly giving u a price on an aftermarket cat! I will give u 300 if it works because i know it will not! good luck with that. 767 is a good price from a dealer. And the code should be po 420 cat effeciency low bank 1.

Replying to: toptech (Apr 22, 2009 3:54 pm) Do you know that you're one of the reason's aftermarket catalytic converters, perfectly good catalytic converters, can be purchased so cheaply..??   A lot more profit/markup for factory converters so of course aftermarket, possibly from the exact same supplier but absent the factory logo/#, converters are a lot less expensive, inordinately so.   Supply & demand.

Replying to: wwest (Apr 23, 2009 7:58 am) Ur wrong. If u could read, u would see that this is the main problem people putting on aftermarket converters and having the same problem. Keep it up with the bad advise, U will be in the same boat as many on this thread. U must be like many other mechanics that put them on, and then when they dont work u have no clue what to do. Or how to propperly check one. Most aftermarket are not teir1 or lev complient.
