Will aftermarket catalytic converters mess up the O2 sensor?
It is possible that aftermarket catalytic converters can mess up the O2 sensor. When installing an aftermarket catalytic converter, it's important to ensure it is compatible with your vehicle's O2 sensor. Some aftermarket catalytic converters may not be designed to work with the specific type of O2 sensor in your vehicle, which could cause the O2 sensor to malfunction or give incorrect readings. Additionally, if the catalytic converter is not properly installed or if there are any leaks in the exhaust system, this can also affect the accuracy and performance of the O2 sensor. If you're concerned about the potential impact of an aftermarket catalytic converter on your oxygen sensor, it's best to consult with a qualified mechanic who can assess the situation and make recommendations.
