Check engine light came on and spit out 3 codes today.

P0150: O2 Sensor Circuit Bank 2 Sensor 1
P0130: O2 Sensor Circuit Bank 1 Sensor 1
P1173: Lambda sensor aging tv bank 2Drive cycle C:Signal out of range - above maximum / below minimum- AKA: RIght side (Passinger) Downstream(after cat) o2 Sensor failure.

Related? Or am I looking at just replacing all the sensors? Might as well do all four.

Thanks for any leads guys.

 

You only need the front 2.
Personally I would just replace the front 2, reset the codes and wait and see.
Amazon.com has them for cheap.

 

I can get them through work for cost so I'll just do that, thanks!

 

Dude hook me up!!! How much are they at cost?

 

Depends what brand. Bosch, Delphi etc

 

Well NGK's are $50 each off of Amazon with free shipping.
How do you compare to that?

 

NGK 25017 has a high MSRP so the cost is already hight, retails for 150$
NGK 25044 is sort of low cost. Could do those for like 30-35 each, I'd have to double check.

 

The front's are what I am interested in.
I dont care about the rears.
So let me know please, no hurry.

 

Does your truck have AELS? The more expensive ones are listed for Discos with it.

 

Yes it does have AELS.
