Factory Oxygen Sensor, Rear, 7/95-96 300ZX Turbo

Unfortunately, this item (and the part it supercedes to) has been discontinued by Nissan. We now offer a replacement version of this item; see 11-3554-1 in Related Items.

Supercedes to 11-3554, which is currently unavailable.

Description:
This downstream Oxygen Sensor, located in each catalytic converter, gives the ECU a secondary measurement of how much oxygen is left in the exhaust after it has passed through the cats. It then sends a signal to the computer, which uses that input (along with several other signals from various components) to make adjustments to the fuel flow into your engine. A bad O2 sensor can cause several issues, ranging from reduced fuel economy to a failed catalytic converter. Failed O2 sensors are one of the most common causes of failed emissions tests. These genuine, original equipment (OEM) secondary sensors were added by Nissan to bring the Z32 up to OBD-II standards. Sold individually; 2 required per car.

Supercessions:
This part number is 'superceded'. Most of our supercessions originated with Nissan. A part made for a Z31, for instance, may actually be the same as the part made for the Z32, but it was given a different number. Nissan would then later supercede the number, so that if you ordered the part number for the Z32, what you would actually get is the original part number for the Z31 (or vice-versa), as they are the same part. Other times, supercessions can exist between different parts on the same car, as is often the case with hardware of the same size. These supercessions were Nissan decisions, where replacing the 'superceded from' part with the 'superceded to' part results in identical performance. The vast majority of them are simple numbering changes, where the parts are literally identical. In some cases, the two parts are identical in fit and function, but the finish is slightly different, or the non-critical overall dimensions are slightly different (like one starter housing being '' shorter than the other on the non-attached side). They do not affect the function of the part, and in many cases, the 'superceded-to' part improves upon the 'superceded-from' part.
