As our cars become increasingly dependent on computers, manufacturers keep adding more sensors. Some high-performance engines can have an oxygen sensor for every cylinder. A typical car has one oxygen sensor that measures the oxygen content of gases leaving the combustion chamber and another that monitors gases leaving the catalytic converter.
Driving with a faulty oxygen sensor can not only cause poor mileage and increase exhaust emissions but can also damage the catalytic converter, leading to an expensive replacement. A faulty oxygen sensor will likely cause your vehicle to fail the smog test as well.
When replacing the oxygen sensor, our technicians will scan the codes, check for coolant or oil leaks (which are known to damage the oxygen sensor), inspect the exhaust system for vacuum leaks and holes, check electrical connections, replace the sensor, verify that everything works per manufacturer specifications, clear computer codes, and take the car for a test drive to ensure that everything functions as expected.
So, if your vehicle is suddenly getting poor gas mileage, or the check engine light comes on, it’s time to schedule an appointment. Driving with a faulty oxygen sensor can generate much higher levels of exhaust pollution and may result in catalytic converter damage, leading to needlessly expensive repairs.
