Ive cant seem to get teh MIL to stay away on my car with the o2 fouler trick. I was getting a LOW VOLTAGE readinng which means the sensor wasnt seeing anything at all. which means its too far out of the flow. i dont knwo what to do, or how to move it further in, it seems im the only person that the foulers hate beause im lost.

please help.

 

At times antifoulers do not work.

 

How many are you using? The normal mechanical fix requires 2 antifoulers correct? Why not just use 1 with a small-medium hole. That way you will get a reading, but not one to throw a bad 02 code.

I thought the voltage read from the primary O2 not the secondary?

 

voltage is read from both, your first o2 is a a/f sensor that is supposed to fluxuate alot, your secondary is a catalyst effiecny sensor, that isnt supposed move nearly as much, if it goes out side of parameters suchh as HIGH the pcm thinks your cat is hollow/not thre, if its LOW clogged cat.

and i used 1 at first im trying 2 tomrrow see what happens and hope for the best.

 

use 2, been using the antifoul since 2003, no cel
