Go to the NSX Wiki page / Repairing your NSX and click on Service Manuals under Reference Sources. This will take you to a page with links to the service manuals. You can get a copy of the manual that applies to your 2002. In the section of the manual on the fuel injection system, there is a complete list of the OBDII error codes. There will be 4 error codes of the form Pxxxx that apply to the O2 sensor heater failures. Match the number displayed on the code reader with the number in the list and it should point to the failed sensor.
Code p0135 02 sensor heater circuit bank 1 sensor 1

Got the info here from that link
P0155.02 Sensor Heater Circuit (Bank 2, Sensor 1)
P0141.02 Sensor Heater Circuit (Bank 1, Sensor 2)
Bank 1 = Rear (cylinder 1-3)
Bank 2 = Front (cylinder 4-6)
Sensor 1 = Primany, before cat
Sensor 2 = Secondary, after cat
So I need rear stream of Primary sensor right?

Yes replace the O2 sensor that is before the cat on your rear cylinder bank. Just before, check that the wiring is ok (who knows...).
I still couldn't find part # for Denso, NTK and NGK sensor.
Assuming it is for a 2002:
DENSO = 2344730
OEM = 36532-PBY-003

Put in your car info. You will get what you need. Front and rear.

thank you
Got the sensor, now can anyone help me where does sensor located? And how hard is it to do it? I saw the diagram earlier on someone post but couldn't find it so. Thank you
Read post #6 one more time before you jump in. Get an O2 sensor socket, rachet and breaker bar. Pb blaster also help for stubborn sensor..
So rear cylinder, toward the rear of the car, sensor before cat converter..
Spray pb blaster, let sits for 15mins. Longer if stubborn.
Before installing new sensor, apply thin coating of anti-seize compound which came with sensor. Then reinstall. Done..
Simple really.

I hate to ask silly questions but I assume to fix this issue (error code P0135) I will need to access the engine from the underside?
Yup. I disconnect the harness from top and just right underneath there's plug. Easy and solve the problem!

OK thanks. I don't have lift ramps but this sounds like a good opportunity to invest in some. So other than the O2 sensor socket, rachet and breaker bar (and WD40 or equivalent) is there anything else I need?
