Help guys my o2 sensor keeps going bad. Cel code 1 keeps showing up. I just changed it last month and now its bad again. what is making it do that?

 

did you buy a bosch sensor? sounds like it.....

 

Could be^^, or he's running really rich and frying it. Doubt it though. What's your boy's setup?

A denso 02 sensor. Heard nothing but horror stories about the Bosch's

 

Only ever use Denso (or NGK, i hear) oxygen sensors.
These are OEM parts at significantly less $$ than dealership.

Save yourself the headache and just get one that has a connector, too.

Bosch are probably the worst o2 you can buy.... I have had the experience of 3 going bad before I learned my lesson.

 

Is the top of the o2 sensor hitting the bottom of the chassie? This can cause the wires to fray and ground out... which would throw the p0141 or what ever code thats for the o2 sensor. I have a test pipe on my car which I had to offset the rear o2 sensor... for the longest time if i hit a bump or something hard it would cause the wires to short on the bottom of the chassie.

Check out the clearance under neather the car... just look at where the o2 sensors meet and make sure theres space so they arnt resting up against anything.
