anyone able to tell me if ill need to buy the o2 sensor simulators for o2 sensor behind the cats? or are they just for when you install headers without o2 sensor hookups?


oh one more silly n00b question, i keep reading WOT in posts, and im sure i should know what it means, but its been a while since i been on here.

 

If you remove your catalytic converters you will need O2 simulators in place of the rear sensors otherwise you'll throw a code.

WOT = wide open throttle

 

ahh ty for the reply, i could only find one o2 sensor behind the cats and its before the pipes Y together, this seems odd to me that they wouldnt put the sensor after the Y as to get a reading from both cats output.

 

I just put my sims in the other day. There is another 02 sensor closer to the manifold on the y pipe on the right side. Lay under your car on ramps from the front. Find the starter, feel slightly in front of it on the y pipe (02 sensor sticks straight up so it's not easily visible. ) Just follow the wire and you'll see the plug, it's kinda hard to get to and your car has to be really cool to get it, be careful cause I burned my arm on the starter even after 2 hours of cooling.

 

the one you described is after the cat?
