Status Lights
The AEM Pressure gauge has two status lights, see Figure 4. The status light on the
left will flash if an out of range low voltage sensor error is detected. The status light on
the right will flash if an out of range high voltage sensor error is detected. In either
case, the needle will point straight downward to signify an error. See Table 1 for
corrective actions.
