The oxygen sensor can be removed from the exhaust manifold using a special oxygen sensor socket (which has a cutout to clear the wires), or a. In the case of using 1 wire oxygen sensor the voltage read by emu for stoichiometric mixture is 2.95v, for the 4 wire sensor it is 0.45v. The sensor numbers shown are (bank, sensor). However, the concept is the same for 1, 2, and 3 wire universal sensors.
