Bad front catalytic converter - 2002 Toyota Tundra

My engine light was on and Toyota says I have a bad front catalytic converter. They reset the light but didn't have the part in stock. They said the light will come back on and when I was ready, they would order the part and install it for $1700.00 part and labor.

That's a lot of money. Is it difficult to get to? Where is it located and what issues might I run into if I try to replace it myself? Where can I find a maintenance resource to research the project? If the cost is mostly the price if the part, then I may as well pay the man.

    I have 155,000 miles on my truck and passed the Ga. Emissions test less than 60 days ago with no issues. Toyota tested it for free and the paperwork indicates Bad FRT CAT Converter but does not list a diagnostic code. I can't remember when I had the plugs changed but I think it was within the last two years (15,000 miles).

  • danyoung1999 May 11, 2009

    Thank you. These are all things I can do. I know nothing about changing out the front cat or where it even is! When I complete this I will have to wait to see if the engine light returns to know if I fixed the problem.

  • danyoung1999 May 11, 2009

    I have the 6 cylinder (SR5). I also researched my bills and found the last time the plugs were replaced was at 75K and I just went another 80K so I will do that too along with the rest of your recommendations before I attempt messing with the converter. The engine light came on that time too and the tune up solved the problem. I will at least find the converter so I know if it must be changed.

    I haven't made the corrections yet. Will have to respond to resolution when recommendations are complete.

    The front cat is is in the exhaust system right after the engine as it comes down out of the engine compartment. It kind of looks like a muffler. Which engine do you have?

    You need to get that code. I would go over the ignition system thoroughly before replacing this cat. Replace the distributor cap, rotor, plug wires, and plugs if you don't know for sure when they were done. Toyota's recommended plug change interval is way too long. At this mileage, these things are simply maintenance and should be done regardless, but I think they may solve your problem.

    Toyota cats don't fail that often. How many miles on your truck? Have you had the spark plugs changed, when? What was the code number? Other things can cause a cat code, you really need to make sure that you're fixing the cause of the light coming on, not the symptom.

Just so you know, "Walker" makes a bolt-on cat for this truck and it costs about $150. They are not as good as the Toyota cats, and you really want to keep the factory one if possible. With that kind of mileage on your plugs, I'm certain they're fried.

I have a 2002 Dodge Stratus 3.0, when accelerating the engine chugs and engine light flashes. I heard it's a bad catalytic converter, is this true?


A plugged converter will cause a NO power situation where the vehicle is unable to expell exhaust gasses and cause poor acceleration. A flashing engine light is the result of a misfire. ( spark plug/coil/injector/wiring ). The engine should still be able to accelerate but will have a noticeable hesitation while doing so

My Tundra 2000 4.7L V8 won't move fast, the engine stops whenever i try to press the turtle or accelerate in fact the engine starts very well even when the car is at pack but when i try to race or fire on...


Press the turtle? Could be many things, such as bad TPS, MAF, leak in hose between MAF and throttle body, vacuum leak, coolant temp sensor, bad catalytic converter or muffler. Any codes set?

2002 Toyota Rav4....check engine light""is


Here are two of the most common causes of the check engine light.

Most common, MAF ( mass air flow ), sensor. A faulty MAF prevents the computer from determining the correct fuel/air mix ratio.

Oxygen sensor. ( front and rear, front meaning before the catalytic converter, rear meaning after the catalitic converter. The front measures the fuel/air mix being sent through the catalitic converter, the back measures the emmisions and lets the computer know if any fuel/air mix ratios need to be adjusted. Both of these can trigger the check engine light.

I hope this helps you.

2002 toyota rav 4 / code po420 whats wrong ?


You have a cat converter ie eficiency code. Most shops are willing to sell you a cat converter and make a quick buck. However you can save some major money if you can find out what is wrong. A cat converter doesn't just go bad by itself something causes it to fail. Most likely a bad oxygen sensor or a dirty mass air flow sensor. I would replace the oxygen sensor in front before I replace converter. Reset check engine light and see if light comes back on. If it stays off you just save about 600 dollars. Oxygen sensors cause cat converters to go bad. So fix the cause first, then if you have to replace converter.

Check eng light trouble code PO420 bank 1 on toyota camry 2002 le replaced top oxygen sensor reset codes and check eng. light came back on.


More often than not the Cat is bad. Replacing the sensors is the easiest move. Reasons for the cat to go bad will be related to something else wrong with the fuel management and emissions systems in the car, improper sealants or chemicals used on prior repairs causing damage to the cat

Aftermarket Catalytic Converter for 2002 Toyota Solara (camry)


You can Install ANY Catalytic Converters that you wish on the Car. There are only Sensors Before the Converters. The only forseen Problem that I can see is: Do you have Smog Tests in the Area Where you live???? If so, You may have no Choice but to Install the Expensive ones or it May not Pass the Emissions Smog Tests. Here in Oklahoma, We do Not have Smog Tests and can Run any Exhaust that we Want But, Not everywhere in the US Is like this. Please Rate My Response! Thanks!

Check engine light on code is P0155-02


I had to replace both o2 sensors on my 2002 Tundra after about 50K. Toyota recalled this problem afterwards and refunded my money. My solution to you is to not worry about which one is bad and go ahead and replace both, because I had one bad and before I could replace it the other went bad also. PS: You'll have to purchase a special socket to remove them and unless you pruchase the Toyota product ( I used O'Reilly parts), you have to cut and splice the wires with a waterproof splicing kit included with the sensors. Just follow the instructions, not a hard job.
