Alright, Ive read my Haynes manual about checking the Air/Fuel sensor and I have a few questions:

1. What can I use for pins to insert into the harness to check the voltage?

2. It says to insert the pins in terminal 3(+) and ground terminal 4(-). My harness looks different from the one in the manual. Is terminal 3 the white wire?

3. What readings should I be getting for an operating air/fuel sensor with an ohmmeter? 3.0v to 3.3v when running? On idle?

4. Would this multimeter work, along with it being on the right setting?




Thanks, and sorry if these questions are nooby, I don't have much car diagnostic knowledge.
