Unless they're doing something different, you should find 5.0 volts on the supply wire, 0.2 volts on the ground wire, and between 0.5 and 4.5 on the signal wire in the middle, depending on throttle position. These sensors aren't typically adjusted anymore as they were on some early '80s models. The Engine Computer will relearn the characteristics of the new sensor.
