bank 1 refers to the side of the engine that #1 cylinder is on , and sensor 2 refers to downstream , after the catalytic converter. , this link shows bank 1 on a 2001 nissan maxima V6 being on the firewall side . if you had a 4 cylinder it would be downstream after the catalytic converter .

The mass airflow can get dirty and you will get trouble codes for everything under the hood except for the mass airflow. Try unplugging your mass airflow and driving the vehicle, if your problem goes away you need to clean the sensor. Buy some mass airflow cleaner though because other cleaners can damage the coating on the sensor.

Are you looking for a serial number of a model number? The 1998 pathfinders have the VG33E engine (introduced in 1996)

SOURCE: how to replace a knock sensor on nissan pathfinder

It's located deep in the valley! Under the "LOWER intake manifold". copy and paste this link in your browser, or try clicking on it. It may be helpful to you.

I didn't find this link until after I had already disassembled my truck. This is the hardest job that I've taken on thus far, hope I can put it all back together properly. I changed the gaskets on the valve covers since I had everything off.
To answer your question: It's under your lower intake manifold, so it's a hard job!

SOURCE: what side is my o2 sensor (bank 1 sensor 1) on for

Bank one is on the side of cylinder one. Cylinder one is typically on the driver side. Although, you have to be careful here. Just because the code mentioned the O2 sensor doesn't mean the sensor is bad. For instance, a code of P0171: sensor indicates lean, bank one sensor; one is not a bad sensor. That is a good sensor telling you that the engine is running lean on bank one. If you get a different code, then it could the be the sensor.

Fuel air mixture too rich on a 98 nissan pathfinder


My guess would be a fuel injector or fuel pressure regulator problem, or a Mass air flow sensor.
The O2 sensor does not come into play until the engine has run for a couple of minutes.
Is the check engine light on ?

Nissan pathfinder 1998 code p0325 what sencor is it there are 4 Sencors ???


It is the knock sensor. But before you do anything first check the vacuum line which is on the front right tire on the rear side of the tire where small hose from charcoal canister up over the shock to the purge valve. That vacuum hose from the purge valve connected to a metal hose and then the metal hose connected back to a rubber hose on the purge valve. that metal hose because it gets rusted cause a leak causing Injector 2 to missfire.

O2 sensors in a 97 gmc 1500 with 5.7 liter


bank 1 is the drivers side bank, so b1s1 would be the drivers side closest to the engine. if the truck is equipped with several 02 sensors then bank 2 or b2s1 would be passenger side closest to the engine. those are called upstream o2 sensors and the others downstream b1s2 and b1s2 b= bank 1= drivers side s=sensor 2=downstream. hope this helps.

Is bank 1 on the o2 sensors the 1 located on the drivers side? Vehicle is a 98' GMC Safari 2wd.


You have it right Avalanche.
Bank 1 is normally the one with the #1 cylinder side.
So Bank 1 sensor 1 is the first one downstream, bank 1 sensor 2 is the one after the catalytic converter.

O2 Sensor


Well, Bank 1 is the passenger side of the vehicle. Are you replacing upstream or downstream 02 sensor?

The upstream is in the exhaust manifold. The downstream is further down in the exhaust pipe. Upstream would be designated by the code HO2S1- B1 and the downstream would be indicated HO2S2-B1.

In either case, you basically unplug the wiring connector, use a 7/8 wrench (or an O2 sensor socket which has a groove cut in the side to allow the wiring to not be pinched) and loosen the sensor and install the new one (with anti-seize on the threads) and plug the connector in.

The upstream sensor is pretty easy- the downstream can be a little more difficult, but is not too bad.

Hope this is helpful!!
