I know this sounds odd but there is a method to my madness

 

my o2 code is illuminated (P0134)

 

If the rear O2 sensor is looking for a difference in air quality compared to he front....if I totally had the o2 sensor hanging in atmosphere (simply

hangin in the engine compartment.......shouldn't that get rid of my code light?

 

the reason I ask is this.......I had a double o2 cheater installed for a few years

as luck would have it....it rotted and broke off

If will be a job taking the converter off and trying to get the old threaded part out....and my inspection is due (NY) in a few weeks

 

I need the code cleared

this will give me additional time to fix the darn thing

It's not air quality that the O2 sensor reads. Only oxygen content.

Pulling the sensor into open air would read high oxygen content, and still set a p0420 code.

 

You might try an ez-out on the broken piece. Maybe it will grab enough to pull the threaded section out. PB blaster and heat will help.

 

If it wont come out, maybe JB weld would hold well enough to get it past inspection.
