What is 0902 code? I found that for A32 platform in Japan and Europe that means problem with rear O2 sensor heater.
What about NA models?

 

Are you sure you read the code correctly? Check it again. http://forums.maxima.org/showthread.php?t=104931

Use that.

 

Yeah, I've checked 3 times. And it comes on in about an hour after ECU reset.

 

0902: downstream oxygen sensor heater or circuit fault ( ref: Haynes )

Kevlo : would you add this one up?

The rear O2 sensor has no effect on PCM control of the air/fuel ratio mix.

My suggestion for fixing: fool the ECU with a simple automotive low wattage lamp bulb. Locate the oxygen sensors 2 heater wires (these 2 are identical in color) and install a no 194 (for example) 12V light bulb on them. The rear sensor connector is under the driver seat: easy to work on. Splice these 2 wires and install the bulb somewhere under the seat.

A new code for the rear sensor might pop up after the 0902 clears away, in which case I guess you will want to replace the sensor or get a sensor simulator (that is what I installed)to turn off the CEL. This lamp bulb is inexpensive, it is worth a try.

 

I can't edit after 24 hours

 

No I meant add it to ECU codes doc .files (I tought you were the owner of that file , sorry)

 

Well, this week or next week I am going to make a hread that converts all the PXXXX codes to DTM style according to the Haynes manual. So it will have that code and more. I will add the link to the ECU codes doc file as soon as I finish.
