Where is the oxygen sensors located on a 1997 infiniti q45?

On a 1997 Infiniti Q45, the oxygen sensors are located in two main locations: one sensor is positioned before the catalytic converter (upstream) in the exhaust system, and the other is located after the catalytic converter (downstream). The upstream sensor is typically found on the exhaust manifold or just after it, while the downstream sensor is located further along the exhaust pipe, near the catalytic converter. To access them, you may need to lift the vehicle and remove any necessary undercarriage components.
