How can I remove the sensor from the circuit so that the Electronic Control Unit doesn't see it? If I pull F13 fuse doesn't that just take the o2 sensor heater out of the circuit? I ask this because ford dealer said this was why my car is running so bad. Before this it was the catalytic converter, which I replaced for no reason, same problem. When I removed O2 sensor in front of cat it was black in color not sandy brown.

Why did they tell you the rear sensor is a problem? Why not just get a soldering iron and some heat shrink tubing and fix the melted wires? Altough I am not suggesting this, what others have done to address P0420 codes, is to build a MIL eliminator for the post-cat sensor. The cost of said elimiator is only a few bucks. Black Carbon on the sensor is not uncommon and not necessarly a problem. Last edited by fdunford; 03/16/06 06:00 PM. 96 Sport 2.0L - 190,XXX miles

I removed melted wirring and installed new tonight. It Still runs real rich. Anybody know what voltage range the brain box should see coming from a good O2 sensor?
