    Can someone check their Bentley to see...

    Can anyone with a Bentley see if there are ECU pinouts?

    I need to know which pin on the big connector is for narrowband (rear) o2 sensor input and which pin is for wide (front) o2 sensor input...

    Any help would be appreciated.

    I sold my Bentley last week and bought a new Rolls Royce! (sorry)

      I assume you have the 1.8T. I looked at a couple of the years and the pinouts appear to be the same.

      Diagram No. 64/10 (Engine code AWW) shows on the 121 pin connector pins 51, 52, 70, and 71 go to the "Heated O2 sensor" which has a 6 pin connector (the other 2 pins are for a heating helement)

      Pins 68 and 69 go to the "O2 sensor behind three way catalytic converter" which has a 4 pin connector (again other 2 pins are for a heating element).

      Hope that helps.

        Actually, I had that info already :P I need to know which wire does what - ground, voltage, signal, etc.

            Supposedly its not in there, Bart also checked for me last night.

            I think I might have to just pull the plug from the sensor and then test each pin or something like that.
