The Autometer 52mm electronic narrowband air/fuel ratio gauge helps monitor lean conditions by pairing with factory narrowband O2 sensors (0–1V) to alert drivers of potential lean burn under load. It’s intended for vehicles that retain a factory narrowband sensor or that use Autometer’s compatible narrowband sensor. The gauge features an LED radial bar graph display, is not compatible with wideband (0–5V) sensors, and may require the Autometer 2244 narrowband O2 sensor if the vehicle lacks a primary factory narrowband sensor.
