Re: Atmopheric pressure

C18 Marine (ADEM III or Acert) do not have an atmospheric pressure sensor as they typically operate at sea level.

This would indicate a false alert.



Re: Atmopheric pressure

The cat C 18 engines operats basede on surrounding atmospheric pressure and temperature, if the pressure and temp is not meating  the requirment then engine power will reduced / derate from the actual power,


Mostly this problem will hapens due to the sensor fault.
