Where
The O2 sensor on a 2002 Pontiac Montana is typically located in two places: the upstream (pre-catalytic converter) sensor is found on the exhaust manifold or just after it, while the downstream (post-catalytic converter) sensor is located after the catalytic converter along the exhaust pipe. To access these sensors, you may need to raise the vehicle for better visibility and reach. Always ensure the engine is cool before attempting to work on the exhaust system.
