the part no. are 64,2387,79856
And they are expensive to replace... (i replaced one @ $400)
The oxygen sensor is located on the exhaust manifold and is the only item on the exhaust with wires going to it.
The 2000 Nissan Pathfinder has a total of four oxygen sensors - two before the catalytic converter, and two after the converter. The front sensors have 3-wires, and the rear sensors have 4-wires. For a good quality OE-style sensor, they'll cost around $100 each.
hi, my friend the cost to replace the oxigen sensor depends if you go to the Nissan dealership is about $120.00 for one oxigen sensor or you can go to the discount auto parts, will cost $70.00 and it's easy to replace. you can do yourself and save a lot of money!! but make sure what sensor is not working because your Nissan pathfinder have 4 oxigen sensor. one before the catalistic and one after the catalistic. but Nissan pathfinder have two catalistics.
If the Nissan truck is either a V6 or a V8, the oxygen sensor will be located in the manifold. Sometimes it will be placed just below the manifold.
The 2002 Pathfinder oxygen sensors are critical part of the engine management system. You can find the oxygen sensors in the exhaust system.
I have a 1995 SE and it has only one. It's located after the two sides of the manifolds meet just before the pre catalytic converter. You can access it from the driver side right under the driver's side door.
The upstream oxygen sensor is located in the exhaust pipe between the exhaust manifold and the catalytic converter The downstream oxygen sensor is located at the catalytic converter outlet
between the exhaust maniflod and the cadillac converter
The 1998 Pathfinder right rear oxygen sensor can be found in the cargo compartment. The oxygen sensor will be beneath the cargo floor, where the spare tire is housed.
Just one and its located right in the middle of the front of the motor.
IN THE EXHAUST SYTEM meaning a 4 cylinder has 2 a v6 has 4. IN THE EXHAUST SYTEM meaning a 4 cylinder has 2 a v6 has 4.
in the exhaust manifold. is there any place to buy a used one?
4 oxygen sensors (2 front and 2 rear)
All O2 sensors are threaded into the exhaust system at various points.
The first oxygen sensor is on the exhaust tube after the manifold but before the catalytic converter and can be easily removed with an inexpensive O2 sensor removal socket that you can pick up at the parts store when you buy the sensor. The tool is recommended because it has a slot cut in the side for the wires so you wont destroy them or the connector.
It is located before the Calaytic converter
There are 2 oxygen sensors on an 04 frontier pickup 2.4litre. One is located after the catalytic converter (on the exhaust Pipe) and the other is between the exhaust manifold and the catalytic converter.
Bank 1 Sensor 2 is located in the front of the engine, on the left side toward the bottom. It has a 3 pin plug that is located in front of the engine just under the plastic engine cover.
There are two oxygen sensors on a Nissan Sentra. This vehicle is an ultra-low emission car, thus needing only two oxygen sensors.
its screwed into the exhaust manifold. On the driver side below the spark plugs closest to the firewall .
1 is on the intake manifold and the 02 sensor is right befor your cataylic converter
Check this site out, it shows you. http://www.nissanhelp.com/diy/maxima/projects/nissan_maxima_o2_sensor_identification.htm
bank 2 is on the left side of the engine or the side closest to the front of the vehicle. So the oxygen sensor would be on the exhaust coming from the left side.
