Prius (2004-09) :: Check Engine Light On / Catalytic Converter Failed
I just moved to Colorado with my 2009 Prius and on the fifth day here the check engine light went on and the dealership said my catalytic converter failed. Luckily I was still under warranty. Is this related to the altitude or just a coincidence?

My wife's car is a 2002 Prius, 149 k miles. Lately the check engine light has been coming on. I took it to the dealership, and their assessment is that the catalytic converter needs to be replaced. They are recommending about $2,000 + of repairs. While I am contemplating the practicality of investing that much in keeping this car going I'm wondering if it harmful or dangerous to continue operating this vehicle.

I just took my 2005 Camry to get smogged and it failed. The reading said that my evaporator and my catalytic converter failed. I reset and drove her for almost 200 miles to get the reading settled, but that did not work. I checked all my fuses and the smog-guy and I have no clue what the issue could be. I don't think that the catalytic converter needs replacing since she only has 60,000 miles on her, but what could be the problem that it keeps saying 'fail'.

View 1 RepliesHonda - Cr-v :: Check Engine Light On - Faulty Catalytic Converter
The check engine light on our 2005 Honda CRV (146,000 miles) came on and stayed on. After a week of driving with the light on we brought the car to the dealer to have it checked. The dealer diagosed a faulty catalytic converter given a P0402 diagnostic code and didn't think the P1078 code for the intake manifold a problem. The dealer also stated that the oxygen sensors were fine. We declined the dealers offer to replace the catalytic converter for $2,170 and the check engine light was reset. After two weeks of daily drifting and 1000 plus miles the engine light is still off. Did we actually have a problem? Why hasn't the light come on again?

I live in CA and recently my car passed the smog test, but failed inspection because the check engine light on the board was on. When the diagnostic test was done, it said there's a problem with the catalytic converter. It's so frustrating because the car's emissions are within limits. , I was thinking... Is there a way to get the catalytic converter to run cleaner without replacing it? If it can run long enough to pass the diagnostic test, my car could pass inspection.

2004 Chrysler Sebring Sedan, 4 cylinder dual-overhead cam. My check engine light came on this morning and the code came out as the catalytic converter. The car seems to be running fine, at least no recent changes. I'm debating replacing this vehicle soon, and I'm wondering if it's worth working on the catalytic converter. I recently replaced the cam shaft position sensor as well.

My check engine light has been coming on and off and it seems to show P0420 for catalytic converter. The light stays off for about a week and it'll come on for a day or two and off again.
Wouldn't a failed converter stay failed? Can P0420 be triggered by loose/bad gas caps?

I have a 2002 Toyota Prius that is currently in limp mode...
Took it to the dealer for diagnostics and they said the Catalytic Converter has failed...So I went online, bought a new one and replaced it. The symptoms prior the Cat replacement were still there...mpg loss, power loss, and exhaust air was not exiting the end of the pipe but actually leaking out the connection point where the Cat and the manifold met.
Ford - Mountaineer :: 1997 - ABS Always On / Engine Light Comes On Occasionally With A Catalytic Converter Fault
The wife's 1997 Mountaineer, 5.0 with all the bells and whistles, Every time she stops, wet, dry, snow, any type of surface, the ABS brakes activate just as she comes to a stop. Heavy pressure, light pressure, doesn't matter. She says it sounds like a cow mooo-ing. 138,000 miles. New pads and rotors were installed 40K miles ago (about 3 years ago) she doesn't drive much but the noise is aggravating. No check engine light, or ABS light. Seems to come on when it gets below 10mph consistently. The Engine light comes on occasionally with a catalytic converter fault, replaced the converters but still get the light. I don't think it is related.

Chk engine light is on. Checked it at Advance Auto and indicated either cat or the O2 sensor (rear). So, I went to replace the O2 sensor and learned the hard way that you can't just unscrew the nut. I torqued off the stud to which the O2 sensor attaches. Muffler shop told me you need to heat up the stud/nut first to remove it. Oh well, lesson learned. So, I'm looking at replacing the pipe with the catalytic converter attached since I can't seem to fix the broken stud (or actually get the one I didn't break off). The problem is, my car is apparently a CA model and has the special cat on it. I live in VA. What sort of problems might I run into if I replaced the cat with a non-CA version? They are significantly less expensive. This is for a 2003 Toyota Siienna

1996 4runner here (187,500miles), with weld in after market cat (on when purchased, with less than 1000 mile on it). started throwing the 420 code beginning of last summer. Replaced both O2 sensors and same results. Was coming on after every 30-40 miles after resetting, replaced wires, plugs, cleaned throttle body started coming on ever 120 miles or so. Now in the middle of winter it has gone 450 miles and still has not come back on?? Does the winter fuel blends in Georgia, or cold more dense air make a difference on cat performance? Still plan to replace it with a direct fit with a warranty but curious if I am overlooking something.

Toyota says the code is P0420 and the Catalytic Converter is rattling under heavy acceleration showing the Catalytic converter is bad and should be replaced. Toyota wants 2,334.00 which seems very high to me. Is it the Catalytic converter? The car is a 2004 Toyota Prius.
View 12 RepliesToyota - Repair - Corolla :: Loudest Rumbling Exhaust Sound / Catalytic Converter Replacement?
Yesterday my 1995 Toyota Corolla (which runs well otherwise) started making the loudest rumbling exhaust sound I've ever heard whenever I stepped on the gas pedal. It also felt like it had trouble accelerating when I would try to get going after a stop. I took it to a mechanic right away, who says it needs a new catalytic converter and resonator pipe.
My boyfriend says this is a repair he could do. He has done some car repair and worked with a mechanic before, so I am considering trusting him on that, but I don't know what types of repairs he's done before and I know he has never worked on this model. What would you take into consideration whether or not it would be safe to attempt this repair at home?
Camry :: 2006 SE Lost Electrical Power After Replacing Catalytic Converter
06 Camry SE I4
I had to replace my catalytic converter because of the code I was getting. It wasn't difficult to do, but took me a while because I had to transfer the thread rods to the new CAT. Once the new CAT was installed, I went to test her out, but noticed that the car all of a sudden, has no electrical power. Nothing at all. I checked all fuses and nothing is blown. The only electrical I messed with on the car was the O2 sensor.
Car has a brand new battery from yesterday. The only thing I didn't do is install a support bracket on one side, because it was missing a bolt and one thread rod was stuck in the old CAT, i couldn't remove it.
A friend suggested that the missing bracket may be causing a ground issue. Is this true?
