My ets light has been on and I shut it off every once in a while. I know it needs to be replaced but I am going to run it until it just stops working. The cars runs 100%. My question is my ce light went on and I got an error from a pre cat o2 sensor. Is it realy bad or is the etc causing this fault. I have reset it several times and it comes back as the o2 pre cat o2 sensor. I just don't feel like spending another $250 if I can help it.
Thanks

my understanding of an etc is the module for your air bags,the ECU is the cars brain,it gets information from the o2 sensor ,to both start your car , and the correct fuel mix,but check the wire at your o2 sensor as may have a short there.

Thanks for the response. I may have gotten the etc wrong.The light that is on is for the throttle body which needs replacing. I am wondering if the throttle body light is on could it make the o2 sensor light fault?

the throttle has a throttle control module they can fail due to needing a software update.

no that will not give you the o2 sensor error ,so you have two things are wrong,that is why you check the codes.you say you have a light on for your throttle,so that can be needing a software update.or failing throttle module.

Thanks Daniel for the reply, how do I reprogram my ets or throttle body and how do I know if the throttle body is bad or just need a reprogram? I ordered a o2 sensor because that is the only error I am getting.

what it can be is with an o2 sensor failing,information is not going to your throttle control module ,so as the only code is o2 sensor ,then deal with that first.

I changed the o2 sensor and the car still has no power and rough power. I did let it sit for 2 days and it ran perfect for about 40 miles. I shut the car off nd it did it again. I have cleaned the TB and checked for vacuum leaks which there are none. I also checked fuel pressure and it was at 45 psi which i think is normal. Any ideas would be gratefully needed.

what you can get is a failing mass air flow sensor, a lot of people get fooled into thinking it is the O2 sensor, they do fail, that is why you must check the codes, and do tests to check what is failing , Google this part.

Thanks for your help Danielm85948. It seems no one can help me with this issue. I disconnected the mass air flow while running and it ran worse and I shut the engine off and it almost didn't start with it unplugged. The odd thing is that is never stalls it just idles rough and steady and always starts. Rpms stay the same as well no fluctuations.I am running out of options but I am determined to find this issue.

have you checked the fuse for the o2 sensor, I had a 440 that was doing strange things and it was the fuse in the built in heater circuit for the sensor.
