Got code P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1),

I have about 106k
Passenger side cat done last month and driver side covered under warrenty a couple years back.

I know im in need of new 02 sensors.
My question is- Is it front or rear 02 thats just before the cat curves I should be ordering?
and should I act quickly or is some thing bad going to happen
Or anything else I should be looking for??

That's ohlord's footnote
Shouldn't you replace all O2 sensors at 100k mark?

 

[KADE]

Yes you should...but did I?, Is the question

I didn't know if it just triggered because passenger side cat was replaced recently...

Yes, it's the O2 sensor closest to the engine on the passenger side. May just be coincidence that it follows so close to the cat replacement since it is old, or it may be that the tip of O2 sensor was polluted (touched) when it was swapped from the old pipe to the new pipe.

I'd change at least the front pair.

13798 is the passenger side, $90 at autohausaz
13642 is the driver's side, $96 at autohausaz

If you're DIY-ing and want to save a bit of money, 15738 is the universal for all four of yours, they are $76 at autohausaz.

Or if you're not in a hurry, the direct fit ones are $75 and $85 at amazon with free regular shipping, universals are $64.

Slight price edge for the 13642

At the moment, a legitimate eBay seller has slight price edge on the 13642 for $70.85 + $7.95 for Priority Mail shipping.

Yeah, but he is coding for the passenger side... and if he's really trying to save money he'll only replace that one. LOL...Kade you know I'm kidding, right?

...and should I act quickly or is some thing bad going to happen...

That's a matter of opinion. Bad O2 sensors are hard on the cats but how hard and for how long you can run it/them before you do any significant damage is debatable. I'll agree with Greg here about replacing both pre-cat sensors as soon as practical.

Well i was going to change just the passenger side Just kidding
