I need the one after the cat I get code P0130 for rear O2 failure. I can get one from the dealer for 150.00 or JR Nissan for 118.00 or on the link tell me your thoughts or if there is any way to make sure the old one is bad. I think it is original with 120K MI.

P.S I got this code a couple of days after the cat back was installed I think the mechanic ruined it.

 

got mine from pep boys, gotta get Bosch, thats what nissan uses

 

I used the OEM version from Auto Medic Supply (Walker brand). The sales guy, Mike, is a great guy. It's very easy to install too.

Free shipping. Borrow a tool from autozone. 1 hour job for non-experienced.

 

You'll need a 12mm tool, not a 16mm. The 16mm only works on the front two.

Before you replace the O2 sensor, make sure you don't have an air leak between the cat and the catback. Air leaks can trigger 0707.

 

If it is the sensor then buy the cheapest rear 02 sensor you can find.

The rear sensor is only for reference to determine if the cat is working. It doesn't change air/fuel misture at all. It is emissions sensing only.
You can probably just pull it out and spray it down with Gumout and get another 30k miles out of it.

So that sensor failure code doesn't put the engine in safe mode or do all codes put the engine in safe mode.


Also is 120k normal for the sensor.

 

Nope, the rear sensor doesn't affect performance at all. Just the front two.

Thanks I might just wait until the light really annoys me.

 

120k is pretty good for any 02 sensor. They usually don't make it past 100k.
My rear sensor went at 102k. My fronts went within 8k of that.
So, you might as well get ready to replace the front 2.... it's coming.

You can get them for $90 for the pair as mentioned. One thing about leaving the CEL on is that you won't know when the front sensors go until you've paid for them is gas guzzling.
