Status Lights
The AEM Temperature gauge has two status lights, see Figure 4. The status light on
the left will turn on solid if the temperature is less than 100°F (40°C). The status light on
the right will flash if the temperature exceeds 300°F (148°C). Both status lights will
flash if the sensor is disconnected. The needle will point straight downward if the
temperature exceeds 300°F (148°C) or the sensor is disconnected. See Table 1 for a
description of the conditions.
