Issue: Some 2021-2022 F-150 Raptor vehicles built on or before 06-Jun-2022 may experience a rattle noise from the exhaust at the exhaust tailpipe actuators. This may be due to the exhaust tailpipe actuator valves rattling inside the muffler assembly. To correct the condition, follow the Service Procedure to reprogram the powertrain control module (PCM) and install new exhaust tailpipe actuator valve springs on the exhaust tailpipe actuator valves.

Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:

 

Parts

Service Part Number Quantity Description Unit of Issue Piece Quantity
ML3Z-5K245-B 2 Actuator Valve Spring 1 2

Quantity refers to the amount of the service part number required to repair the vehicle.

Unit of Issue refers to the number of individual pieces included in a service part number package.

Piece Quantity refers to the total number of individual pieces required to repair the vehicle.

 

Service Procedure

1. Check the PCM for software updates using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. Is there a software update available for the PCM?

(1). Yes – download and run the PCMPowertrain Control Module (PCM) Software Update app. Proceed to Step 2.

NOTE: Advise the customer this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle’s computer to learn the transmission’s unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days.

(2). No – proceed to Step 2.

NOTE: When removing the actuator shields, it is recommended to use a wrench or socket on the backing nut when removing the 10mm bolt. This will help prevent damage and/or minimize distortion to the shield.

2. Remove both exhaust tailpipe actuators and exhaust tailpipe actuator valve springs by performing only Steps 1-4 and 6-9. Refer to Workshop Manual (WSM), Section 309-00C.

NOTE: Make note of the positioning of the exhaust tailpipe actuator valve shaft after the actuator has been removed. The valve has a 90 degree range of motion and is likely positioned closed when the actuators are removed.

3. Install the new exhaust tailpipe actuator valve springs. The steps below are to be performed on each actuator independently.

(1). Position the bottom of the service exhaust tailpipe actuator valve spring (Figure 1) on the top of the exhaust tailpipe actuator valve shaft. The top of the service exhaust tailpipe actuator valve spring with the rectangle shaped opening, should be facing upwards. Refer to Figures 1-2 for orientation.

 

(2). While holding the service exhaust tailpipe actuator valve spring in place on the top of the exhaust tailpipe actuator valve shaft, install the exhaust tailpipe actuator by slightly pressing downward and rotating clockwise to lock the actuator in the assembly.

(3). Carefully inspect the service exhaust tailpipe actuator valve spring to make sure that the actuator and exhaust tailpipe actuator valve shafts are properly seated. A properly installed service exhaust tailpipe actuator valve spring should appear as shown in Figure 3.

 

4. Install the actuator stud bolts and tighten to 89 lb-in (10 Nm).

NOTE: When installing the actuator shields, it is recommended to use a wrench or socket on the backing nut when tightening the 10 mm bolt. This will help prevent damage and/or minimize distortion of the shield.

5. Install both shields and the bolts and tighten to 89 lb-in (10 Nm).

6. Connect the wire guides and the exhaust tailpipe actuator electrical connectors.

7. Using the Ford Diagnosis and Repair System (FDRS), download and run the PCMExhaust Tailpipe Actuator Position Relearn app to relearn exhaust tailpipe actuator positioning.
