Oxygen Sensors
So Im getting this code now after installing sensors. P2A00 A/F Sensor 1 Bank 1 Circuit Range/Performance. Does this mean the Front sensor is not working correctly? Im guessing I should purchase another sensor. Which company is the best? Bosch, Ntk (Ngk), Denso or something else? My tech told me these are fragile and they break easily.

Which one should I buy? Any specific company that is better suited for the Z? Looks like the front two sensors are the same sensors.

Bosch, Ntk, Denso make quality sensors, you wont go wrong with any of them and most of the OEM sensors are made by them anyway. I installed so many of them and never ran into a problem. However, do not get the universal o2 sensor, buy the one that made specific for your vehicle.

Im going for Bosch, Im guessing we just stick them in and reset the cpu. Im having a tech do this. The ones up front seem to have a plug at the end of the cord. Is there any difference in the two front sensors located at Bank 1 and Bank 2 that are closer to the fuel injector. Also the cord is longer then the ones located under the car. ( Which are the sensors after the cat converter )

I replaced the bank 2 sensor 1 o2 sensor with a direct plug-in Bosch unit and so far it is working great. The connector even matched the color of the stock o2 sensor and both had NTK Japan markings on them. I ordered the Bosch sensor online and paid about $85 shipped vs. the local parts stores wanting $140+tax for the same sensor.

Yea I just installed the two sensors and the light came back. Must be something else wrong with the car. I might have to check the fuel injector or something. I remember reading on my report that I might have engine running lean. Which my friend told me that maybe more air is coming in and its not balancing out.

From the dealer they gave me that code and a description that said engine was running lean and also the voltage at idle is kinda low. I got two more Bosch sensors since they seem real good. Let me read and see if this thread can help me out. Thanks.

I certainly would not use some of the no-name universal fit sensors... but Bosch meets or exceeds OEM requirements and is used by many OEMs. It isn't as if Nissan actually manufactured the o2 sensor that came in the 350z. It would seem that even the "OEM" sensor does not last the life of the car or I would not have needed to replace it at 60k miles...

Yea I put the direct one in there and it seems to just go bad real fast. I think something else is wrong like the air and fuel ratio isn't balancing out so I have to figure that out.

It is weird though we got a bosch O2 sensor today and when i opened the box denso was stamped on the sensor. I have never seen this before maybe some one at the parts store screwed up but weird none the less.
I would go with denso or OEM (which i believe might be made by denso)
