Walker Products Oxygen Sensor P/N:250-25174
Walker Products 250-23521 front oxygen sensor for the 1996 Nissan Maxima V6 3.0L measures combustion efficiency by reading the oxygen in the exhaust gas. The Walker Products oxygen sensor gives the ECU the diagnostic feedback this application needs.
A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. A damaged wiring harness or connector can sit behind the same symptoms, so track down the cause before you buy a sensor.
This sensor is made for one specific application and position, and it is a direct-fit replacement for the 1996 Nissan Maxima V6 3.0L.
Fit and size
Build and materials
This listing holds one oxygen sensor, and the 1996 Nissan Maxima V6 3.0L takes one in this position.
Does this Maxima oxygen sensor fit the 1996 Nissan Maxima V6 3.0L?
Yes. Walker Products 250-23521 is a front oxygen sensor for the 1996 Nissan Maxima V6 3.0L, and that car takes one in the downstream front position.
Is the Walker Products 250-23521 a narrow-band or wideband sensor?
The Walker Products 250-23521 is a narrow-band oxygen sensor with a 3-wire titania design.
What thread size does this downstream front oxygen sensor have?
This oxygen sensor has a threaded M12 - 1.25 mount.
What signs can a failing downstream front oxygen sensor show?
A failed sensor can show up as poor engine running, higher fuel consumption or an illuminated malfunction indicator light. The sensor, wiring harness and connector can also be inspected for physical damage.
What does the coating on this oxygen sensor do?
The coating shields the electrode surfaces from contamination and erosion caused by combustion residue and particulates in the exhaust. The electrodes carry a gas-permeable platinum layer.
