    I was probe but is not good.
    I must replace sensor on some car witch give precise 1.00V when conditions of some DPFE filter is ok...
    Voltage divider work fine but is not temperature enought stabile.
    ADin on car ECU measure in 0.01 V steps...
    When I have 1.00V that is 0.2KPSA precise and car work fine..
    If I have 0.999V that is not good ! or 1.02V is bad too ...
    Sorry for bad English...
