Reduced engine power

Motorhome Workhorse W22 2008 has been in reduced power since last year , mobile mechanic came out and said we need a new throttle pedal.

Purchased one from Workhorse parts, fitted it ourselves . tried the throttle relearn .

DTC code coming up again U0107 Lost Communication with throttle actuator control module.

Got another HG mechanic and he said it was the throttle actuator module.

purchased one from Workhorse parts , fitted it ourselves as it says it is a plug and play.

still coming up with the same error code

 

Checked everything . batteries . fuel levels , fuses. wiring

Anyone else have this issue

  • Thank you for your input . As I live in Alberta Canada and have to order from Workhorse USA , order has to be paid before shipping and been advised and checked  by the mechanic .

  • I suggest next time let the mechanic fit it, which you should have done in the first place.  that way if it isn't the issue you are not out money.
