swapped o2 sensor, now a more CEL'S

**casawhites4** · 01-04-2009 02:06 PM

do you think it made a difference that i took the o2 sensor out of my stage 3 piggie pipes, and put them into a stock S4, now on to the codes!
does it matter that i took these 02 sensors out of my stage 3 car, that had piggie pipes???

now the codes are.
16518.P0134
o2 Sensor Circuit Bank 1 No Activity

16544.P0160
o2 Sensor Circuit Bank 2 No Activity

17524.P1116
HO2S heater circuit Bank 1 Sensor 1

17548.P1140
Bank 2 Sensor 2 Internal Resistance to large

why did all these codes pop up after i swapped my o2 sensor from my piggie pipes from my stage 3 to a completely stock s4...i have no idea..

What were the codes you had before? seems like those cables might have a short in them. are they spliced at all?

If you have codes after swapping those 02's with good 02's then i would try checking the wiring back to the ECU. otherwise try using new sensors. If the sensors were good before on the CASA then I think you should the wiring.

I'm trying to make some moves and keep up maintence, cause me and the GF just bought a Townhouse so i'm trying to move around some things to open my budget.

thats real good vern, congrats on the purchase man..def congrats on the purchase, and how the hell am i gonna follow the wires back to the ecu, lol..goodness, thats gonna be a mission, last i can remember is that my o2's were ok...but now im not sure...and im not trying to buy an o2 sensor for a few hundred..

Thanks Alex, I would try the Universal Bosch 4 wire o2. I have one and i spliced it to my old harness and it works fine. paid like 90.00 bucks for it. You might be able to find some cheaper on ebay. I bought mine form ECStuning.

It will be a mission but just saying, i'd rather rule out a short somewhere since your not trying to spend some coin on new o2's.

just dont get how both of them would crap out after i swap just one of them...doesnt make sense, and it makes it seem like it could be wiring to the ecu..

yeah, went to advance auto parts, and bought the 4 wire bosch o2 for 70 bucks, put it in and resetting the codes, seeing if i get any of them back...will know in a few hours if so or not..thanks vern, will see how it goes.
