Where is the oxygen sensor on a geo prizm?

The oxygen sensor on a Geo Prizm is typically located in the exhaust system. There are usually two sensors: the upstream (pre-catalytic converter) sensor is found near the exhaust manifold, while the downstream (post-catalytic converter) sensor is located after the catalytic converter. To access them, you may need to lift the vehicle for better visibility and reach. Always refer to the vehicle's service manual for specific details and locations.
