Q: Check Engine code reads "catalytic converter"

asked by on

The Check Engine code reads "catalytic converter."

Hello. If you have a check engine code for a catalytic converter then most of the time that is exactly what you need. In some cases a bad oxygen sensor can make it look like there is a bad converter. A mechanic would need to install a computer scan tool to read live engine data to see if the oxygen sensor is reading correctly or not. He would also do a temperature test of the converter to see if it is functioning properly. After diagnosing the issue the mechanic can recommend a solution that may include an oxygen sensor replacement or replacing your catalytic converter.
