The O2 sensors in a 2003 Chevrolet TrailBlazer are placed both before and after the catalytic converter. They monitor the amount of oxygen in the exhaust gases leaving the engine. It is recommended to replace the oxygen sensor every 60,000 to 90,000 miles, as it wears out over time. Neglecting signs of a faulty O2 sensor could jeopardize the integrity of the catalytic converter and potentially lead to further damage to the vehicle. The sensors can accumulate carbon and soot buildup over time, and may get coated with substances like grease, oil, or other liquids present in the exhaust emissions.
