Why did I need to replace the catalyst converter?
We had it towed to a guy that did work on it before for us with the new catalyst converter in box brand new. He said he cut into the pipe in front of the catalyst converter an it was still making the pipe red hot… Next thing I know the car won’t start so they replaced the starter, an spark plugs.
What is the trouble code for a bad catalytic converter?
The most common trouble code when it comes to a bad catalytic converter is the P0420 code. If you observe delays when accelerating or notice that your car does not accelerate properly and loses power when driving in steep areas, while all other parts like spark plugs, filters etc. are fine, then it is your catalytic converter’s fault.
What causes a check engine light to come on after a catalytic converter is replaced?
This trouble code appears when the unit can’t sufficiently reduce the carbon emissions from the exhaust. However, a catalytic converter does not normally wear out. There is usually some other reason for their failure. If you spend $900 or more to replace the catalytic converter, you may discover the check engine light coming on again later.
What happens when a catalytic converter is choked?
When your catalytic converter is choked, there almost no working by it. Emissions done by car do not go through catalyst present in the converter and hence converting of high pollutant gases to low pollutant gases is not observed resulting in high emissions.
What happens if you replace the catalytic converter?
If you spend $900 or more to replace the catalytic converter, you may discover the check engine light coming on again later. Some mechanics will tell you to try replacing the oxygen sensors first, to see if that solves the problem. There are two of them, one before and one after the catalytic converter.
How can I clear an error code on my catalytic converter?
This will reset the computer and clear the existing error codes. Locate the oxygen sensor that is downstream (closer to the tailpipe) of the catalytic converter. Remove the sensor, and take to your local car parts store. Find the part called a spark plug defouler.
What does check engine light mean on catalytic converter?
The check engine light will come on if it’s below this threshold, determined by oxygen sensors that are located before and after the catalytic converter. The sensors will trigger an Onboard Diagnostics (OBD) trouble code that’s stored in your car’s computer. OBD Code P0420 means the catalyst system efficiency is below the threshold.
Can a non fouler make a catalytic converter work?
Legend has it that if you use a spark plug non fouler you can trick your engine computer to think that everything is working fine. I decided to put this theory to the test on my 2003 kia sorento with a p0431 and you won’t believe the results!
