Bosch Oxygen Sensor P/N:16643
Bosch 13264 right oxygen sensor for the 1996-2000 Nissan Pathfinder V6 3.3L and other vehicles senses exhaust oxygen and reports it to the ECU. This Bosch O2 sensor is a heated, narrow-band unit that helps reduce emissions.
A failing oxygen sensor can bring a check engine light, rough running or lower fuel economy, but those signs have other possible sources. Find the cause before replacing the sensor: with the engine off and cool, look over the wiring and connector for chafed or melted insulation, and leave signal testing to a shop.
It is an oxygen sensor for the 1996-2000 Nissan Pathfinder V6 3.3L and an oxygen sensor for the 1997-2000 Infiniti QX4 V6 3.3L, in the downstream right position.
