bgambino Posted December 9, 2013 Share Posted December 9, 2013 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 Link to comment Share on other sites More sharing options...
Fairtax4me Posted December 9, 2013 Share Posted December 9, 2013 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. Link to comment Share on other sites More sharing options...
