Check FSM?
Logic and reason tells me they should be the same. Take it out and compare it with the new one before buying it.
And O2 sensors do serve a purpose - they help get your engine get to proper operating temperature when cold and they help regulate emissions for OBD. Faulty O2 can make the ECU make wrong fuel adjustments that can F-up your gas mileage.
