O2 sensors on PF A8 4.2 Datasheet
 

Hi
Does anyone have the part number of precat o2 sensors on the Audi. Also would anyone know how to find the datasheet for these sensors by any chance....

I think Bosch make the sensors but I m not sure on the actual make of the sensor...and so not sure of how to find the datasheet....this will tell me how the output voltage varies with lambda.

Thanks in advance for any help.

Sh*t is that how you spell your name? I added you to my insurance as it took it down by £650 but spelt it Ranjit, better get it changed.

... and the prize for the "most off topic reply" goes to..... :D

Made by Bosch, part No: 021 906 265 AK
Voltage varies just like any narrowband lambda sensor
0.2V or less - lean, above 1.03
0.45-0.5V - 1
0.8V -rich, 0.97 or below

In normal operation constantly changes between 0.2V and 0.7V

O2 voltage output and lambda
 

Thanks

That's cool....sounds like there are only three specific states for AFR with narrow band sensor...so better just to observe the varying voltage...rather than lambda.

Thanks
