P0139 Questions
Hi guys, at the beginning of the week I got the check engine light, I went to the near autozone and got code P0139, the guy at autozone didnt want to reset the code with the tool so later in my home I disconnected the battery to reset it, the light came on today again, went to another autozone and got the same code, so looks like is not going away,
so a couple of questions:
what do you suggest? immediately replacement of the oxygen sensor?
if yes:
should I got the OEM?, the autozone version? or the cheapest ones that rockauto.com sells?
and lastly where the sensor is located, as far as I know the truck has 4 O2 sensors, 2 kinds of them according to the location,
thanks in advance,
Regards

Get NTK O2 sensors. The last one I did the upstreams on, I went through the wheel wells. If they're original, get ready to curse !
I think 3 of them are the same part number and the left upstream I think?...is the oddball one, so the pigtail can be routed away from the exhaust.

I took a look on the truck here is a picture of the driver side:
the passenger side:
a closer look to the one that is on the upper:
if Am I right the one that I need to replace is the one on the red arrow, looks easy compared to the others one,
Am I right?
