They are not that easy to hook up to an electrical source since the connector is not something you come across at Radio Shack. If you are going to store it, put it in a zip lock bag along with some desiccant bags and store it in a cool dry place. -- Ray O (correct punctuation to reply)

I guess that it's possible, but I doubt that both of the ECUs have the exact same problem to bring up the same code, so I'm guessing that the problem is somewhere else. I'm completely stumped and about ready to just give up and take it to the dealer. Anyone else have any ideas/suggestions before I do that? Thanks again for all the help, Dave

RayO would know more but there are ways to test them. I don't know if you have multiple sensors in your car or not. Usually you have two. One before the cat and one after the cat. I believe PO141 probably refers to a specific sensor. From there, you can do certain tests to verify whether or not the sensor(s) are bad or the cat is bad. Probably just a bad/delayed/faulty O2 sensor that just needs replaced. I believe I had that code and my front O2 sensor was bad. Replaced it and that code went away.

The description of the code is "Post-convertor O2 Sensor heater or circuit fault" and I have actually tried replacing the O2 Sensor with a Bosch and a Denso replacement part and neither of those fixed the problem. I did tests to make sure that the wiring was fine and it all appears to be ok, so that's why I'm stuck without any ideas of how to fix it but I'm definitely open to any and all suggestions. Dave

Cats rarely go bad but I suppose it's possible. It may even be under warranty as I think they have an 8 year, 100k mile warranty or something. After you replaced the O2 sensor, did you reset the computer so that it can re-calibrate? |
