Air Fuel Ratio Meter Wiring Diagram
34+ Air Fuel Ratio Meter Wiring Diagram Images. When all the fuel is combined with all the free oxygen, typically within a vehicle's combustion chamber, the mixture is chemically balanced and this afr is called the stoichiometric mixture. These sensors have 3 or 4 wires, check with vehicle manufacturer, or wiring diagram for your specific vehicle to learn which wire is the signal.
Remove air fuel ratio sensor (for bank 1 sensor 1) (a) remove the wire harness clamp from the air fuel ratio sensor.
Looking similar to a conventional oxygen sensor, the a/f sensor has more wires. (b) disconnect the mass air flow meter connector, then remove the wire harness clamp. 3 air / fuel ratio meter and oxygen sensor operation the a/f ratio meter is a voltmeter with a range of 0 to 1 volt. The reading might be lower if the engine has not.
