2001 Acura Integra Question: oxygen sensors



J-Integra, Atlanta, GA, March 12, 2012, 16:37

Do both oxygen sensors need to be replaced when replacing the catalytic converter? My acura integra has 172000 miles on it and needs a cat converter replaced.

    In principle it is good work practice to replace them to help the new cat work efficiently and last. Over time the sensors get "lazy" but it is all based on economics I guess! If the sensors are bad the computer in your car will flag them as bad but may not flag a marginal sensor.

    Agree with the technician, it will in the end produce the best outcome from repairs
