This bulletin applies to 2019 and 2020 Ram 1500, 3500 and 4500/5500 vehicles. The bulletin involves inspecting the Julian date on the throttle body and possibly replacing it.
Customers may experience a MIL illumination. The technician may find DTC P2100 set (electronic throttle control motor circuit/open – Bank 1). The customer may also note that the truck is in limp home mode.
-
Inspect the throttle body for an “S1” or “S2”. If S2 is present, the correct throttle body is already installed. If S1 is present, inspect the Julian date.
-
If the four digit stamped Julian date on the front of the throttle body is on or between 2419-2549, proceed to the next step. If not, the correct throttle body is already installed.
-
Inspect for a green dot near the barcode on the throttle body housing. If a green dot is present, the bulletin is completed. If not, replace the throttle body and seal, and clear DTCs.
