So I have a wideband and I have been slacking on getting it put in (work too many hours). Can I temporarily plug it into the second sensor bung until I get to the exhaust shop? I know I'll get a CEL, but that won't change the way the car runs will it? 2nd O2 should only be for emissions.

 

it should work

 

Has anyone actually done this?

 

i did for a bit, its fine.

 

Did you unplug the 2nd 02 completely or did you tie it up? Thanks for the quick answers.

 

i unplugged it completely, no use in tying it up

 

yeah unplug it completely or it will might read crazy

 

Ace - I don't think it matters what it reads. It has no affect on the AFR I thought. Doesn't it only tell you if the Cat is working correctly?

I would just unplug it for the time being.

 

Yeah, I think it just takes readings, but is not calculated into the fuel or timing maps. Unplugging it would be much easier. Thanks to y'all.

 

^^ lol i got lost on that one.. i was thinking about my setup where the secondary can be used for close loop operation..

but yeah disconnect and keep it safe, those things can be sensitive
