What is a faulty catalytic converter


The catalytic converter takes exhaust gases and converts them into water.
When the converter has failed, it is stopped up or otherwise not able to covert the exhaust gases.

I have a 2003 toyota corolla, the check engine light turned on, and the dealership said i need the catalytic converter replaced....for 1,000 dollars, can i fix this myself?


Check with Muffler man or rainbow muffler or what ever aftermarket exhaust place you have in your area. They can usually come up with something cheaper call more than one to keep them honest. For $1000 you can get very creative.

Why did the catalytic converter on my 2003 Toyota Highlander fail? How do I prevent this from happening again?


I had the same thing happen on a 2003 Corolla. The dealer said one possible cause was too much oil which was blown on to the fins in the catalytic converter causing damage. The catalytic converter is a pollution device so unless you need to pass an emissions test it may not be a factor.

I have a 2000 Corolla. Engine light was turned off by mechanic but came back on in 1 week. Should the catalytic converter be replaced?


If the code was (catalytic converter below threshhold) its more tlikely that you will not need to replaced the catalytic conv.but is a possiblity. First check your o2 sensors for proper function. These are electrical units in your exhaust that read your air/fuel ratio and are a lot more likely to malfunction.

I have an engine light on to my Toyota Corolla 2003; diagnosed by the autozone OBD11 SCANNER P420. I replaced the oxygen sensor and the light deleted. After driving the car for 30 miles the light came on...


Hi

The trouble areas associated with this code are as follows:
1)Gas leakage on exhaust system
2)Oxygen sensor
3)Heated oxygen sensor
4)Three–way catalytic converter

The idea is to check for exhaust leaks first then the front sensor and rear sensor. If these all check out then the cat needs to be replaced.

Hope this helps. Thanks for using fixYa

2003 toyota corolla catalytic converter


If you want the check engine light to stay off, make sure that the converter is a direct fit, and not a universal. It should work fine then.

What'll happen if I dont fix P0420 code in my 2003 Toyota Corolla


in reality nothings happen, and your saying what do you need to do so you will not encounter this problem again well honestly you cant depend on life on catalytic so i suggest to do your general tune up like changing spark plug,wires,check timing,fuel filter,oil change the way they should be change so it helps the engine burn near stoichiometry because during the oxidation happening in your catalytic if your engine rich or lean or misfiring it could cause a defective catalytic converter.
