The Autometer Ultra‑Lite 52mm electronic air/fuel gauge monitors narrowband O2 sensor signals to warn of lean conditions that can cause engine damage during spirited driving. It connects directly to factory narrowband sensors or uses Autometer model 2244 where needed; it is not compatible with 5‑wire wideband sensors. The display uses an LED radial bar graph and the gauge requires checking sensor compatibility before installation.
