Just bought a Scangauge D to be installed in my Journey 2002. Searched under the dash high and low, can not find the J Port. Called both
Winny and Freightliner, both say "it's in there", but i can't find it. I have searched both from top and bottom to no avail. Anyone with a journey that has found their's, please HELP HELP with a more detailed LOCATION, ect.
The Cummins ISB 5.9 Engine is a good engine and is generally combined with the Allison 2000MH trany. The ISB 275hp (5.9) is a flat land engine when in a coach. the Allison 2000MH tranny is limited to 600FP torque and Banks enhancement would exceed the limits of the tranny. Unless you are exclusively east coast flatlander like me, go with the 375hp Cat.
The Compressor on a diesel engine is always turning.
To my knowledge diesel air compressors do not pump all the time, most are equipped with a bypass device of some sort. When 120 psi is reaached the regulator forces the compressor into bypass mode until air pressure is required again. If the regulator/bypass is inoperative than the compressor will continue to produce pressure. When the air pressure reaches the blow off point around 150psi +- a safety valve will lift off to prevent high pressure damage. That probably is the air that is being purged continuously. This would also account for readings of 150psi.
Regulator components fail more often than compressors, and can be replaced easily.
