Greeting All!
I just acquired a 2006 Couchman Cross Country with a 5.9 cummins in it. It has been sitting for 13 years
and only has 6600 miles on it. Amazingly enough it fired right up and I am in the process of changing all the fluids. It has 1 code that keep coming back.
SPN0641
FMI= 5 Current Below Normal Or Open Circuit
SPN641 Engine Variable Geometry Turbocharger Actuator #1
So I took to the google machine (and searched these forums) and found a lot of information on what might cause this. A bad actuator or stuck veins in the turbo, or since it is possible open circuit maybe a corroded terminal or bad connection?
Then I went under the bed and opened the hood (if you call it that)? Took a look down and It looks like the turbo on it is old school, oil in and oil out. I do not see an actuator mechanism on it
There are two electrical connections just past the turbo, maybe a temp sensor for one, not sure what the other is.
I am pretty confused, anyone else ever see anything like this?
