Town Car :: 4.6 Engine Catalytic Converter Location?


Oct 20, 2012

I have a 2000 Lincoln Town Car with a single exhaust system, part of/attached to the frontal area of the exhaust "Y" pipe are two lumps with heat shields, the muffler is obvious in the mid-section of the car, but are those "lumps" the catalytic converters, and if so, why two when the older cars had only one?

Honda - 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?

Nissan - Sentra :: 2002 - Check Engine Light On / Catalytic Converter?

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.

Toyota - Camry :: Check Engine Light Came On - Failed Catalytic Converter

I had my local garage do their electronic check when my check engine light came on. They said the code they got indicated a failed catalytic converter and quoted me $720.00 for a California compliant replacement, including labor. I live in Connecticut. I'd like to take a few days to get a second opinion and second quote, but the garage manager said that driving it in this condition would risk fouling the oxygen sensor, which I recently replaced for a couple hundred bucks.

Should I be concerned about fouling the oxygen sensor by continuing to drive the car? 2000 Toyota Camry...

I looked under the car and the rear attachment bolts to the converter are rusted beyond recognition. I'm tempted to try replacing it myself but it may be a bit beyond my skills.

Sebring - Chrysler :: Check Engine Light Came On And Code Came Out As Catalytic Converter

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.

Toyota - Prius :: Check Engine Light Has Been Coming On - Catalytic Converter Need Replacement

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.

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.

Prius (2004-09) :: Check Engine Light Coming On And Off / Showing Code P0420 For Catalytic Converter

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?

Passat (B5) :: Catalytic Converter Replaced, CEL Came On

I recently had my catalytic converter replaced with a non-OEM cat. The check engine light came on and a different shop (different from the shop that replaced the cat) said that it will keep coming on because I had the cat replaced with a non-OEM cat.

Golf IV / Jetta IV :: CEL Came On, Car Needs A New Catalytic Converter

I have a 2001 VT GTI with 155K miles on it. It is in very good condition. I have loved the car except for the high maintenance costs that typically seem to be associated with VWs.

I found out this week after my check engine light came on that the car needs a new catalytic converter and a new new secondary air pump.

Let's assume that this diagnosis is correct and the repair is accurate for the sake of this posting (and I have no doubt it is). In other words, I don't want to get my question derailed on that issue.

The car has new Michelin tires on it and runs well. The problem is that it will fail the state emissions test I am required to take next December, and I will either be forced to have the car repaired or will not be able to get updated license tabs (isn't that sweet?!).

It seems that I have a few options:

1. Get the repair done (ouch) and keep driving the car for a few more years. Repair cost is about what the market value of the car is (from what I have seen).

2. Sell the car "as-is" between now and December and see what cash I can get out of it. Any buyer will discount the value of the vehicle based on the repairs needed. Of course, then I'll need a replacement vehicle of some sort.

Acura - Rsx :: 2004 - Catalytic Converter Malfunction

I own a 2004 Acura RSX that I purchased new nearly 10 years ago. The car currently has 182,000 miles on it. Two years ago (approx. 130,000 miles), I had to replace the catalytic converter and both O2 sensors. This lightened my wallet to the tune of $1,200 (aftermarket franchise, OEM replacement). A few weeks ago, the "check engine" light came on. I used my scanner, and got the dreaded P0420 code, and had it verified by another shop. O2 sensors were OK. What REALLY shocked me was that replacement catalytic converters are only warranted for 5 years/25,000 miles (50k in CA). The first replacement piece lasted 52,000 miles (less than half the miles/years of the original part)

Here are THE QUESTIONS: What killed this catalytic converter? What can I do to prolong the life of this part? My car has the base powertrain that (according to the owner's manual) recommends 87 octane fuel. That's all I've ever used. The mechanic suggested moving up to mid-grade fuel, though he admitted that he wasn't sure.
