Have a 09 Bird with intermittent cummins engine code 2636 VGT Actuator Driver Circuit- Abnormal Update Rate.

Comes on 2-3 times most days within a 10-15 min window then goes out. Driver called it in 3 stops away from being done for the day 2 days ago. Hooked up Insite pulled the codes, checked ecm update,ran calibration test. Driver drove it the next day no issues until this mornings route. Driver ran front half of route no issues/ back half it came on stayed on for 2-3 min went out stayed out for 1-2 min then came back on for another 2-3 min then went out and stayed out. Driver said it has been going on for about a week but didn't say anything for the first 3 days.

ECM has last update, ran calibration test and it passed.Most of the trouble shooting is electrical checks. Before I dig in has anyone had this code ? Figured it would be worth a shot on asking.

Yep...
Ive had a couple do this one ended up getting a turbo replaced under warranty another got a new actuator. An easy way to tell is to go the the rear and turn it on. The vgt actuator does a sweep and you should hear several quick and crisp "zip" sounds. If it sounds like its binding thats whats going on. It only takes a second to tell, and then youll know if youve got to pull the actuator off to see if its the actuator or the mechanical end of the vgt inside the turbo, or an intermittent electrical issue.
