The Pontiac Oxygen Sensor, a part of the emission control system, is used to estimate the ratio of air and fuel in the engine's combustion chamber. The amount of oxygen in the exhaust is measured by the sensor and sent to the engine control unit (ECU). The ECU makes adjustments in the fuel injection to attain optimal efficiency. If your car experiences rough idling, increased emission of pollutants and reduced fuel economy, you may consider replacing the oxygen sensor with a new one.

If your Pontiac Oxygen Sensor is not functioning properly, you should replace it as soon as possible.
