2 wire O2 sensor?
I have a Toyota Camry 98' four cyl. The o2 sensor has two wires! Or is it a AFR? Autozone shows it as a four wire. I looked and it has 2 wires.

One wire is your signal wire that runs back to ecu. its the one that ranges from .1 -.9v. get a meter with a probe and you can probe the wire to see for yourself. My wire was purple.
