I was able to get a Broadband Oxygen sensor signal, the specs are:
* BOSCH LSU PIN Numbers.
* Code 17025.
* Type 4.9 broadband oxygen sensor.
* Auto: Fiat Stilo, 4 cylinders, TDI, year 2006.I would like to know if it is a good or bad signal
as I did not notice any obvious issues in this engine, maybe a slight lack of power by snapping throttle under load conditions but I am not sure about this as it was the first time I drove and played with this car for a while. I mean no data trouble codes showed up via my DEC SuperScan3 scanner.
This is the guy we are talking about:
I would like to upload the *.ps files to the Wave Form Library browser to contribute to the forum as I haven't seen any broadband oxygen sensor in the library but firstly I have to know how to name them; GOOD or BAD.
As for this file you can see the Pump cell current as a math channel from channel A voltage which is hidden but you can get with the right click button on the *.ps files. According to OHM's Law this is Ip current flow calculated after measuring resistor at connector sensor. Resistor value is 109 ohms. This is a good signal I think
Here you are the Measurement cell signal:
I am sorry as I wasn't able to get both signal together. Every time I tried to do it, both signal looked wrong, I mean voltage out of range according to the specs in internet. I think the problem is my scope as I have a 4423 model and as far as I know ground is common for all channels. Maybe I have to hook up an attenuator to every 4423 scope channel or need a 4425 oscilloscope with independent floating inputs, I am not sure at this point, please you tell me!!!
All suggestions to the questions are welcome before uploading the files to the library,
If are not already uploaded by means of the forum
Kind regards and looking forward to enlightment
