    Checked both of the O2 sensors today

    I have battery voltage on both heater circuits and good earths

    On one of the sensors i have 5.6 ohms and zero on the other (heater circuit resistance)

    4.90v constant on one sensor and 4.20v on the other from signal wire (other probe to good earth)

    I have located a couple of sensors for tomorrow so will keep you posted

    Peter
