Subaru - Forester :: 2000 - CEL / Code Is P0133 Came On Randomly - Replace The Catalytic Converter
Mar 24, 2012
My 2000 Forester has 96,000 miles on it. A few months ago, the CEL came on. At first it would turn off every couple of days but would eventually pop back on. I first thought it was tied to putting gas in the car, now I think it was just a coincidence.
Over the past two months, I have replaced the catalytic converter with a aftermarket piece (done by a mom and pop muffler shop) and replaced the front o2 sensor three times. The first two times, I used Bosch sensors from an auto parts store and had the code cleared. After about 50 miles the CEL came back on. Just yesterday, I picked my car up from the dealership where they installed a Subaru fron o2. After about 30 miles, the light is back on again. Code is P0133 - heated oxygen sensor, bank 1 sensor 1, circuit slow response.
Now, the dealership is suggesting I need to replace the catalytic converter with a Subaru converter before they can source the issue.

On my 2002 Subaru Forester (137,000 m), the check engine light came on. They diagnosed and repaired O2 sensor. About 300 miles later it came on again, this time they said the catalytic converter was cooked, and they blamed whatever caused the O2 sensor to fail (or the O2 sensor failure itself). After the repair (about $1300 and 30 miles later), I discovered that the engine oil was so low that it was not showing up on the dipstick (tho the oil light was not yet on). The shop (after admitting that they did not check the oil while it was in there) said it was related to catalytic converter failure. Does this make sense? I have only gone another 60 miles since the oil was refilled, but so far it looks OK. Should I be on the look-out for anything else?

I'm getting smoke from the catalytic converter area on my 2001 Subaru Forester. The smoke smells of rubber or oil. I've only noticed it after the car has been driven up a long, steep incline of at least a couple of miles. I've never seen it happen after normal highway driving. The car runs fine, gas mileage is good, CE light is not on, 85K miles, regularly serviced.

2001 sub forrester. In 2009 it was intermittently stuttering: tuneup, new coil, finally O2 sensor (both) replaced which fixed it. In Oct started to do the same thing. First the back then the front sensor replaced but they commented the flow was low on the catalytic converter but wouldn't say it could be the cause of the sensor issue. Now the O2 sensors are on either end of the converter and the car is starting with early signs already. Is is reasonable that it is the catalytic converter? I am wrestling with just having them do the full tuneup and replace the converter or am I crazy?

That Car Grand AM 2000 2.4L SE
The current problem with the car is that it is not accelerating fast, for example i would push the petal to the metal and only go 25 mph and my RPM would be 3000-4000. Initial my brother and cousin though it was the Catalytic converter because it was getting hot but that has recently been change along with the fuel filter and spark plugs. but the catalytic converter is still gets red hot so i forbid myself from driving it till i fix what every causing the slow acceleration and the temperature of the Cata when i took the error code think P0300 random misfire to the local Autozone they printed me a long list of things that could be a issue my question is what is the likely culprit so i can fix those 1st before shelling out cash to rebuild a engine. may just have to get rid of it at that point. so i guess what am asking is a list maybe top 10 so i can fix them one by one as my money comes in.
Before the accelerating issue the car would randomly stop when i slowed down or stooped that when i replace the spark plugs.

The check engine light came on so I took my car in. My mechanic whom I've used for years told me the following: the catalytic converted had started to come off, in the process it pushed the oxygen sensor up against the body of the car and shorted it out. The total damage is that the O2 sensor and the cat has to be replaced. The line-item estimate was $104 for a sensor and $650 for a cat, plus labor. Total: $1000. Now, I'm looking online and seeing cats that work on my car for far less ($200-400 depending). I talked to another mechanic on the phone who verified cats don't have to be $650. My mechanic said they only use top quality parts with warranty, etc. But the other mechanic said that for a car that he wants to get moving again, a cat is a cat and any new part will, of course, come with a warranty. So... what should I do? Is $1000 too much? If I go with the mechanic who says he can get me down to $700, will that be cheap work on my car? It has 108K miles, and I'd like to get at least another few years out of it.

I've been having issues with my car, i took it to Orielly's & they ran diagnostics, one of the codes said a recommended fix was replace the MAF sensor. Today I took it by an auto shop for them to look at, and the guy said it was my catalytic converter, and I mentioned the MAF sensor, he said fixing the CC would take care of the MAF sensor malfunction. So I have a couple questions...
1. Is what he said correct?
2. If you have a bad CC, does it ever NOT smell bad?
Bc I've never smelled anything other than stinky exhaust, never any rotten egg smell.
It's a 98 Nissan Maxima, 6 cyl. it has 265K miles.

ill be replacing my muffler here soon, its rusted out blows smoke out all the rust holes, and so on. gonna replace with a nice flo master. Question is, when is it time to replace the catalytic converter? 15 years old and 93000 miles, it still seems like its in good shape, but could it be getting clogged? just from the sounds of the exhaust the past few months, it almost sounds like the truck is somewhat congested. The power from the engine is kinda week, but that's the engine itself. I have no real problems getting up to speed. my hesitation issues from before turned out to be water in the gas tank. Figured since im down there does it make sense just to bite the bullet and throw a new catalytic converter on?

We have a 2006 impreza, that we've been told the Catalytic converter is going out. We cannot seem to determine if there are one or two converters on this car, and want to know if this is something that we could do ourselves once we find out where everything is at?

Heard a funny intermittent rattle and my mechanic told me that my check engine light should be going on any time now as my cat converter is bad. The part is about a thousand bucks! Looked on line and see some aftermarket ones from walker and some other retailers. My car has 103K miles on it,.

engine light and flashing cruise control switch--computer says replace bank one---so I replace with factory catalytic converter----six months later light comes back on with flashing cruise control switch and computer asking me to replace bank one---So I use computer to shut light off----four weeks later light comes back on----called dealer they said "we usually replace both banks"---I found it most painful paying for dealer supplied catalytic converter even when I was under the impression that it would keep light off.---This is my wife's car and she is not really buying the piece of black electrical tape I placed on dash over check engine light.---Am I dealing with a bad oxygen sensor ?

My 2000 Nissan Maxima has a PO430 code for the catalytic converter that has been going on and off for over 1 year now. My ? is, how would I know that the converter needs replacing? Someone said there wouldn't be any smell necessarily, someone else said I would be leaking qts. of oil in between changes and someone else said it would get bad mileage. Each one debunks the others comments etc. Also just for info., this car had the ses light come on at 57K miles, my brother replaced 2 of the O2 sensors and I replaced 2 also, one duplicate one and a mass air flow as well.

Does this mean the DPF is shot? I believe its integral with the cat. whats worth checking first?

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.

It came on 2-3 miles after a cold start. 3.6 with 137,000 miles. What's next? First car I've owned that uses very little oil between oil changes.

I have a 2000 Chevy Camaro. Two years ago my catalytic converter went out and I had it replaced. 20,000 miles later my mechanic says that I need to replace it again. Is this accurate? I thought the life of a Catalytic Converter was much longer.

I have a 2003 Subaru Forester with 44,000 miles. How will I know when to replace the timing belt? Is it more a question of miles or age?

I've never replaced a car stereo and have no clue what to look for as far as compatibility goes. My '09 Forester has a am/fm/sat. radio hookup/ 6 cd changer. Do I have to look for a specific stereo head other than it being a 2-DIN?
I'd like to be able to continue using the aux port that is in my center console, and I would like a USB port that I can plug a Galaxy S4 into.

Title says it. Cat is done. Threw code p0420 and am experiencing hesitation at WOT. Already replaced my front o2 (cbfa) and now I'm debating whether or not to get a new downpipe. I daily the car and am wondering if keeping the car as is for a while will damage anything. Cts turbo has a sale for a catless downpipe.

I have this vehicle, which keeps blowing out the catalytic converter, its been replaced 3 times in the last month, and the mechanic doesnt know why, he refuses to put another one on it, until he figures this out.

My husband,who is an engineer and has done all of our car maintenance for decades is stumped by our 2000 Mazda MPV. He replaced the catalytic converter and put every thing back together, but the car won't run. Will start, but dies right away. Took off new cat,and runs with that off, but not sure why it won't run with the cat on.
