No cat tunes and secondary sensors
 

Well I had my cats tuned out cause one of em blew up on me when I had a miss fire issue from the aftermarket coils I had on.

I was wondering am I able to completely remove the second sensors now without an issue?
I'm only asking cause before I had it tuned out I tried the gotts o2 mod and the o2 extenders which basically fried the one o2 sensor cause it didn't ground properly, I'm thinkin. So now I get these codes for the inductance and heating element in the sensor which make my truck run cold. (until I clear them of course :cheesy smile: )

ran into this myself with my offroad y-pipe, even with the rear sensors "tuned out" they still must be plugged into the harness so the PCM atleast can "see" they are preset even though it doesn't use them :thumbs up yellow:

What he said.

Yea sorry for being so slow to respond, I'm horrible at remembering to follow up on things.
I found this out the day after when I tried disconnecting it, so I ordered a new Motorcraft sensor from rock auto for like $36.
Thanks for the responses though!

Rear O2 sensors are not turned off on catalyst emission monitoring from custom tunes are they? Is that more of a special request while ordering tune thing? Or is it possible to de-activate them from reading with the Gryphon?

Upon special request Bill can turn them off when the tunes are written......

Otherwise a person can go with sct and turn them off with the hand held programmer...
