I can't remember which is which, but there's two different types of sensor; zirconia and titania. - I think the zirconia type is more common; it works by giving a voltage between 0 and 1V to give the rich/lean reading for the ECU. Titania requires a voltage input and measures the change in resistance across the probe with the air/fuel mix.Thats a different part number to what should be fitted. The doc on here, and from what ive read elsewhere says the pulsar sensor is not used by any other models. Most of these sensors work from 0 to 1v, but the manual says ours goes to 1.5v so unsure whether it would work
