    Simtec MS71 engine management.
    EMS light on.
    Fault code P0130 lambda open circuit.
    Have replace sensor and checked that the sensor is working with a scope.
    Check wiring continuity between the lamba plug and ECU.
    Live data (using DEC and ACR) shows a voltage of 0.411v for the front lambda with no activity, the actual voltage at the lamba varies when check between 0.3 and 0.9 volts.
    The rear lambda in live data is showing activity.
    Suspect ECU fault, but would appreciate any other thoughts.
    Many thanks Ivor
