Inspection is coming up and I need to pass. I have OBX headers, so based on these codes, what do I need to do?

 

bump

 

a little bit of help please

 

anyone?

 

I am a handy person, but an auto repair rookie, so please bear with me for these questions:

2002 Nissan Maxima SE 6spd (car is not available today so I can't tell if it is a Cali or US car for emissions/sensor type)

Engine light has been on for a few months, Autozone scan yielded the following trouble codes:

P0138: Bank 1 Sensor 2
P0159: Bank Bank 2 Sensor 2
P1167: Bank 2 Sensor 2


Q: Which is bank 1 the front or bank of the cylinders?

I understand Sensor 1 refers to before the Cat and sensor 2 is after cat.

Q: As I am having a hard time visualizing the locations of the sensors and crawling under the car for a 6'6" guy is challenging at best - Does anyone have a diagram of the sensor locations with Bank 1-Sensor 1, Bank 1-Sensor2, bank 2-Sensor 1, Bank 2-Sensor 2 locations identified?

Q: Could someone tell me the sensor locations by passenger side or driver side and before/after cat, etc that would be great!


My plan is to replace the two sensors triggering the codes: Bank 2 - Sensor 2 and Bank 1 - Sensor 2

Q: Which is easier in to use for replacement sensors the non-OEM splice type or the "Bosch" sensor with full wiring? I know there is a big price difference. My thought was if I locate the right sensor I don't have to worry about tracing and re-stringing the harness back to the cylinders - am I "all wet"?

Q: If successful in replacing sensors, can I just clear the code with the battery rest method, or will it still require dealer intervention?

Thanks in advance for your comments. Money is a bit tight and don't want to get by the dealership prices right now. I have searched around a bit, but only have a general idea.

Thank You, exactly what I needed - pictures worth a thousand words.

 

@ spotty J
i just had the same to o2 sensors replaced. Why is that these sensors go out in pairs? Makes me wonder if they really do go out or if its something else...

 

I've been getting P0138 (bank1/sensor2) off & on for the past couple months. Bank2/sensor2 hasn't triggered a code.

However, there is TSB NTB02-051a saying that if you get a code for a rear sensor on one bank, you should replace the rear sensor of both banks.

 

Thank you for the info.

You can clear it with disconnected battery or the pedal dance:
