After months in operation, the oxygen sensor active elements become fouled with exhaust byproducts, affecting fuel economy and emissions. On average, y'all should supersede the sensor or sensors on your Grand Am after reaching fifty,000 miles of driving. If your particular model is equipped with the heated oxygen sensor type---cheque your car's owner's transmission---it should be replaced at about 100,000 miles. Whether you need to change one or more of these sensors on your Grand Am, follow these steps to install the new units.

The upstream sensor will be located along the front end exhaust pipage before the catalytic converter. The downstream sensor is institute right after the catalytic converter on the back exhaust pipe. The sensor's torso is cylindrical in shape, nearly the size of a spark plug, and has a pigtail electrical wire.
