Where is oxygen sensor for 1998 Pontiac grand prix video?

Answer 1

The oxygen sensor on a 1998 Pontiac Grand Prix is typically located in the exhaust system. There are usually two sensors: one before the catalytic converter (upstream) and one after it (downstream). To locate them, follow the exhaust pipe from the engine; the upstream sensor is near the engine, while the downstream sensor is closer to the rear of the vehicle. A video tutorial can provide a visual guide for precise locations and the removal process.
