    Broadband Sensor

    Hi,does anyone know if the broadband o2 sensor data is of any diagnostic value when the engine is cranking over (ie,vehicle wont start).
    The scanner is a Veruse Edge.

    Maybe Check a wiring schematic if the suspect one shares a common 5 volt feed or ground with a sensor that is necessary for the vehicle to start?

      Hi,thanks for the reply.I had a petrol car wrong fueled with
      diesel.I renewed the fuel,spark plugs ect but the vehicle
      refused to start even though i had good compresions,fuel,
      spark,ect,ect.The fuel pressure was about 180 bar at cranking
      and Autodata said it should have been 120 bar max,so i was
      looking at a possible overfueling and thinking of ways to
      prove it. Turns out that Autodata was wrong and the fuel
      pressure was ok. Anyway the car suddenly burst into life
      and now runs perfectly.Thanks again for the reply.
      PS.i dont think it does give any useful data when cranking
      maybe a gas analyser would have been of some help.
