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.
Can a bad catalytic converter lead to engine failure?
A bad or clogged catalytic converter can ultimately lead to engine failure, so it’s important to address the issue promptly. However, having catalytic converter problems doesn’t necessarily mean that the converter has to be replaced.
What to do if your catalytic converter is shot?
If your converter is shot, it may still be possible for you to create a condition that makes your downstream oxygen sensor think that it is actually working. This fix requires that your oxygen sensor is in working condition. Disconnect your cars battery.
What are the signs of a clogged catalytic converter?
1 Engine accelerates poorly or is hard to start. These issues could indicate a clogged catalytic converter, restricting the flow of exhaust out of the engine. 2 A sulfur or “rotten egg” smell. 3 rattling noise when starting the engine 4 Failing the annual or semi-annual emissions test 5 Vehicle warning lights. …

What is the diagnostic code for a catalytic converter?
An illuminated check engine light or malfunction indicator lamp (CEL or MIL) with a catalytic converter diagnostic trouble code (DTC) is the most common catalytic converter problem indicator.
Can a lazy oxygen sensor cause a catalytic converter problem?
You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself. A technician can determine if the sensor is responding as it should.
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.
Why does my catalytic converter keep coming back on?
If the light eventually comes back on, then you have a more serious problem, and you might need that expensive replacement. However, there are still other less-costly causes for a trouble code P0420. Such as: Failing oxygen sensor (remember that’s always a possibility). Damaged wiring of the oxygen sensor connections.
Why are there error codes on my catalytic converter?
This 3 dollar fix will save you hundreds of dollars. Error codes thrown by your cars computer that indicate a bad catalytic converter, actually originate from the oxygen sensors. Typically, a car has an oxygen sensor upstream and downstream of the 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.
When do I need to Reset my catalytic converter?
That usually resets after 50 to 100 miles. If you go for the inspection before the system indicates “Ready” you will fail the inspection. Before the inspection, attach your code scanner and check the status.
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.

How do you find a cat fault code?
Count the first sequence of flashes in order to determine the first digit of the diagnostic code. After a two second pause, the second sequence of flashes will identify the second digit of the diagnostic code. NOTE: Catfaultcodes.com indicates the potential effect on engine performance with ACTIVE fault codes.
