I went to get emission tested today, and came out with 2 codes

P0139 (i searched a little bit, and i think its the O2 sensor)
and P1147 which is MAF i guess?

could some1 please tell me what parts i need to buy and where would be a good (cheap) place to buy it

I want to cry so bad right now

thanks

edit: i have 2002 SE

For the O2 sensors, I bought mine from www.ngk.com and the prices are resonable, they come with connectors.

Hopefully, fixing the O2 codes will help erase the other code too...

Food for thought

"Under normal conditions the rear heated oxygen sensor is not used for engine control operation."

B1 P0139 of REAR O2 SENSOR

which would be the rear of bank 1. I'm not sure of the firing order,so I'm going to guess this one
NGK OE identical O2 sensor 24634 REAR RIGHT $128.85
but could be this one
NGK OE identical O2 sensor 24573 REAR LEFT $81.85
(Whichever one is for bank 1)

Possible causes for code p0139
Harness or connectors (The sensor circuit is open or shorted. )
Rear heated oxygen sensor
Fuel pressure
Injectors
Intake air leaks

Possible causes for code p1147
EDIT: I couldn't find this code in alldata, but would find out what it is. A call to the dealer maybe.

IIRC, Generic scantools don't show codes that begin with p1?? Someone did you a big favor by giving you that code...
EDIT: Nevermind they might if they are emissions related.

I had the exact same two codes on my 2K2 a few months ago.

First of all, there is a TSB related to these codes. It is NTB02-051 and involves replacing BOTH rear O2 sensors and a reprogramming. If you are under warranty, definitely go have this done.

If you are not under warranty and want to do this yourself, you should still get the reprogramming done by the dealer. The reprogramming is SUPPOSED to be covered by the 80K emissions warranty although not everyone has had luck with that. Some have even managed to get their O2 sensors replaced as per this TSB under the 80K emissions warranty.

P0139 and P1147 are both related to the Bank 1 rear O2 sensor. This is the sensor with the white wire. The OEM part number for this specific sensor is 226A0-5Y701. If you are doing this job yourself I recommend that you replace this sensor only and then go get the reprogramming done from the dealer if you haven't had it done already. If they won't cover it under warranty, it'll probably cost you about a half an hour or an hour labour.

Hope this helps.

Merci

I also have a set of codes that keep coming up.
P1320- IGNIGTION SIGNAL primary circuit fault (code came up twice)
- thought it could be my coils but had them checked.
P0300- Multi cylinder misfire detected
P0171- Fuel injection sys. function leans side (bank 1)
P0174- fuel injection sys funcetion lean side (bank 2)
My '00 Maxima used to rev up on its on when starting up. Then all of a sudden she stopped. Now she won't even rev up long enough for her to warm up. HELP!!! ANY INPUT WOULD DO.
