Running too lean while enjoying spirited driving in your vehicle is one of the leading causes of expensive engine damage. AutoMeter’s Narrowband Air/Fuel Gauges pair with older Oxygen Sensors to warn of lean burn conditions under heavy engine load. Connects directly to the factory O2 sensor on many applications, or uses the AutoMeter 2244 Narrowband O2 sensor. Not compatible with 5 wire air/fuel sensors.
- ADDITIONAL NOTES
- Compatible with factory narrowband O2 sensors (0-1V)
- May require model 2244 if the vehicle does not have a factory narrowband primary O2 sensor
- Features LED radial bar graph display (gauge does not have provision for backlight)
- Will not work with wideband O2 sensors (0-5V) - please check your specific application before purchase

The installation guide only shows 3 wires red black and violet but i have 4 wires the extra one is white. where does this white wire go?Thank you so much for contacting us. Very, very early Narrowband gauges had a lighting circuit in them which is controlled by the white wire. It isn't necessary for the gauge to function as the LEDs are always on, but the wire can be hooked to the headlight switch output to provide additional lighting when the headlights are turned on. Hope this helps!Date published: 2018-05-22
Why would I choose a narrow band AFR vs. a wideband?Hi Robert, thank you so much for contacting us. A narrowband AFR gauge uses the older style narrowband oxygen sensor and was designed to tee onto existing OE sensors on older vehicles. These sensor lack the resolution necessary to determine a true ratio and aren't really useful as tuning tools, like a wideband would be. A narrowband will be able to serve as a warning light of sorts for lean conditions reached at WOT. It's an older technology and in most every instance you'll be much better served with a proper wideband. Hope this helps!Date published: 2018-03-29
Hello, if more than1volt is applied to the purple wire ( an error ) will it destroy it's narrow band capability? Thanks for listeningThank you so much for contacting us. While the gauge should be able to tolerate slightly more than 1v, it isn't designed to do so and could result in damage to the unit. They're built to be pretty robust, but, for example, applying 12v to a 1v circuit definitely has the potential to harm the circuit. Hope this helps!Date published: 2018-01-31
