You need to determine which sensor is causing the check engine light to come on. being a freightliner the most likely culprit is the engine oil pressure

On my Renault truck it is in the mirror cowling

Dd 15

what engine has it go
if it is a GM detroit 60 series it is no 6 injector circuit board problem
heavy vehicle fault codes are specific to engine or transmission installed in what ever vehicle
take it to a service center for the engine make and have it properly diagnosed

an answer from just answers reports this
ecu 1 fault means the engine ECM has an internal fault and needs to be replaced
most of the time with this code it is not the ECM itself but usually a wiring problem going to the ECm
there should be 2 fuses for the ECM either next to the ecm in plastic covers by a starter or in a plastic box
check all wiring going to and from the engine and battery grounds
especially the grounds
check for wires rubbed through and loose terminals
take it to a service dealer for a proper diagnosis as it costs money wasting time trying to find the fault yourself as a truck standing still is not earning it's keep
