Attention: If you need the sensor and the gauge , please choose the item of sensor and gauge together.

Air Fuel Ratio Gauge With Narrowband O2 Oxygen Sensor 0258006028 Car Racing Gauge 52MM Digital Voltmeter 2 Inch for 12V Car Volt

Oxygen Sensor Specification:

OEM:0258006028

Working Voltage: DC12V

Signal Line Voltage: 0-1V

Spiral: M18*1.5

Use Wrench: 22mm

Output Voltage: Maximum value ≥900mv/ minimum value ≤50mv.

Response time: (600mV-300mV) ≤100ms.

Response time: (300mV -600mV) ≤100ms.

Starting time: ≤10s

Heating resistance: 8.5~9.5Ω

Internal resistance: 200~300Ω

Connection:

The white line is at heater ab


Black line signal line C, gray line signal ground D

The green wire of the instrument is connected with the black wire of the sensor. The gray line is connected to the negative pole of the battery.


One white wire connect with the car shell or battery negative pole.
Another white wire connect to the ACC line of ignition switch


The white line is the heater and does not distinguish between positive and negative electrodes





About the air fuel gauge, please see the installation instructions.

Feature:

1.When powered on digital gauge will read the voltage for 1 minute and switch to Air Fuel Ratio.It will only switch back to voltage if there is a decrease or increase.

2.It is suitable for 12 volt gasoline vehicles.
