I'm getting that right now, I have the 2 post cat converter stockers in my garage, can I use one of those to get by until I can get the good Denso's to replace them with?

 

I believe the rears are non heated.

 

A lot of the sites listed the fronts and rears as the same part number.

Replaced em both and my fuel filter last night after work. Runs like a champ again. I was getting what felt like tranny slippage in 2nd gear during WOT but it was either running out of fuel due to a clogged filter or the O2 sensor not working correct.

 

they are heated.

Turn the code off

 

I have the rear codes turned off, but I want to know when the fronts are acting up or failing.

 

Well Mine toss's that code non-stop no matter what sensors are in it. the main reason is they do not respond as fast as the computer thinks they should so the PCM assumes they are failing and sets the code...they are just the heaters man turn them off

 

Ahhh, I see says the blind man. The sensor was actually toast, it was black and not responding. I got no response out of it according to my predator handheld.

Since swapping them out I haven't got the code again. I haven't had to do much tuning to my car yet. If I disable that code is there another one that will let me know if the O2 sensor fails?
