On the exhaust pipe right below the manifold.
The 2002 Infiniti QX4 is equipped with a total of four oxygen sensors. There are two upstream (pre-catalytic converter) sensors and two downstream (post-catalytic converter) sensors. These sensors help monitor the air-fuel mixture and the efficiency of the catalytic converters, ensuring optimal engine performance and emissions control.

To replace the rear oxygen sensors in a 2001 Infiniti QX4, first, ensure the vehicle is turned off and cooled down. Raise the vehicle with jack stands and locate the rear oxygen sensors on the exhaust pipes. Disconnect the electrical connectors and use a wrench or oxygen sensor socket to unscrew the old sensors. Install the new sensors by threading them in place, reconnecting the electrical connectors, and ensuring everything is secure before lowering the vehicle.
