Bosch 13273 oxygen sensor for the 1996-1997 Nissan Maxima V6 3.0L and other vehicles measures oxygen in the exhaust and reports the air-fuel ratio to the ECU. This downstream Bosch O2 sensor is a switching-type unit that helps the ECU keep combustion stable and emissions down.
A check engine light, rough running or poorer fuel economy can mean this sensor is worn, though the upstream oxygen sensor or the catalytic converter can be behind the same signs. Find the cause first; if this sensor is at fault, it is the one to replace.
This sensor fits the 1996-1997 Nissan Maxima V6 3.0L and the 1997 Infiniti I30 V6 3.0L. The listing is one downstream sensor, and both cars need just one.
