I have a 2004 Freightliner Columbia w/an MBE 4000 motor. It is running like crap, almost like the turbo isn't kicking in. I think, but am not sure, that the fault indicates that there is a problem with Engine Speed Sensor # 2. Does anyone know where that speed sensor is located? Just replace it?
Thanks
