When there is no UEGO sensor connected to a particular channel, the Status LED of
that channel will remain on solid and the Ready LED will turn off after a few minutes.
The remaining channels with UEGO sensors connected will function properly.
When the exhaust back pressure kit (30-2064) is used, the 4 CH UEGO controller will
monitor exhaust back pressure. (NOTE: The 4 CH UEGO controller is designed to
work with a specific AEM pressure sensor. Do not use any sensor other than the
one included in the Exhaust Back Pressure Kit.) If a pressure sensor error is
detected, the 4 CH UEGO controller turns off all Ready LEDs and flashes Status LEDs,
starting with CH1 and ending with CH4. The analog output voltage level for all 4
channels switches to approximately +5V to signify an error.
