Summary
Some 2018-2021 F-150 vehicles equipped with a 3.0L diesel engine, 2016-2022 F-650/F-750 vehicles equipped with a 6.7L engine, and 2017-2022 F-Super Duty vehicles equipped with a 6.7L engine and built on or before 08-Mar-2022 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P21DD, P20BA. P20B9, P204C, P208A, P208B, P208C, P203B, P205B, P21CD and/or U02A2 in the powertrain control module (PCM). This may be due to water intrusion within connectors C3613 and/or C4851/C3610 on the reductant harness going to the reductant pump/heater assembly and the reductant level sensor/quality module. This may also be due to movement of the wiring harness causing terminal fretting. To correct the condition, follow the Service Procedure to replace the reductant tank harness, the reductant pump/heater assembly and/or the reductant tank, as well as securing the wiring harness using a cable zip tie fastener.

Service Procedure
NOTE: For DTCs P21DD, P20BA, P20B9, P204C, P208A, P208B, P208C this can indicate a concern with connector C3613. For DTCs P21CD, P203B, P205B and/or U02A2 this can indicate a concern with connector C4851 (F-Super Duty) or connector C3610 (F-150, F-650/F-750).
1. Disconnect and inspect C3613 (16 pin connector) at the reductant pump/heater assembly and C4851/C3610 (4 pin connector) at the reductant level sensor/quality module for signs of corrosion. Refer to the Workshop Manual (WSM), Section 303-08 and the Wiring Diagram.
(1). Inspect both the harness side and component side of both connectors for signs of water intrusion. Focus on all pins at connector C3613 and pins 1 and 4 at connector C4851/C3610. Inspect for signs of:
• Visible green corrosion on multiple terminals on the harness side of connector C3613. (Figure 1)
Figure 1
• Corroded pins on the reductant pump/heater assembly at connector C3613. (Figure 2)
Figure 2
• Visible green corrosion on the reductant level sensor/quality module side of connector C4851/C3610. (Figure 3)
Figure 3
• Visible green corrosion on the harness side of connector C4851/C3610. (Figure 4)
Figure 4
2. Follow the appropriate procedure:
(1). If no signs of corrosion or water intrusion are present on either connector or component, replace the reductant tank harness only.
(2). If signs of corrosion or discoloration are present on the reductant tank harness connector C3613 or reductant pump/heater assembly perform the following:
• If there is corrosion or discoloration on the reductant tank harness connector only and not on the reductant pump/heater assembly, only replace the reductant tank harness.
• If there are signs of corrosion or discoloration on the reductant pump/heater assembly, replace both the reductant tank harness and the reductant pump/heater assembly. Refer to WSM, Section 303-08.
(3). If signs of corrosion or discoloration are present on the reductant tank harness connector C4851/C3610 or the reductant level sensor/quality module perform the following:
• If there is corrosion or discoloration on the reductant tank harness connector only and not the reductant level sensor/quality module, only replace the reductant tank harness.
• If there are signs of corrosion or discoloration on the reductant level sensor/quality module, replace both the reductant tank harness and the reductant tank (reductant level sensor/quality module built in).
NOTE: Do not add any dielectric grease to the electrical connectors.
3. Prior to installing the reductant tank, using a 40lb tensile strength cable zip tie fastener, secure the harness to the reductant pump metal lock ring. (Figures 5-7)
