Freightliner Cascadia dd15 eng2 001SPN003464 throttel CMD. 32

Check your throttle plug on the side of the throttle body. The heat on the throttle body tends to cause a lot of corrosion there. You don't want to ignore it too long for it will get worse and then cause the truck to stall out like the key is turned off.

 

OP, were you able to diagnose the problem and find out what exactly was wrong with it? I have the same code on my truck (2014 DD15).

 

The little motor on the side of the intake throttle goes bad on DD15's sometimes. Mine did. Throttles are cheap (about $130) and very easy to change. You can tell if it's working by listening when you turn the key on. You should hear it sweep open and closed.

 

I thought the same thing but when I took the throttle valve out and tried to manually close the flap, it moved freely. I even bought a new intake throttle valve and plugged it to the harness and tried to cycle it by turning the ignition on but it still did not work. Seems like its an electrical issue.

 

Going to check the connectors pins (as mentioned in an earlier post) tomorrow.

 

So what happened?
