6.7L – ILLUMINATED MALFUNCTION INDICATOR LAMP (MIL) WITH DIAGNOSTIC TROUBLE CODE (DTC) P20E8 – BUILT ON OR BEFORE 20-DEC-2016
Publication Date: August 14, 2017

 

FORD: 2016-2017 F-650, F-750

 

ISSUE:

Some 2016-2017 F-650/750 vehicles built on or before 20-Dec-2016 and equipped with a 6.7L engine may exhibit an illuminated MIL with diagnostic trouble code (DTC) P20E8 in the powertrain control module (PCM) memory. This may be due to air that is trapped in the reductant pump and heater assembly not allowing the system to build adequate fluid pressure.

 

ACTION:

Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

  1. Connect the Ford Integrated Diagnostic System (IDS) service tool or equivalent scan tool to the data link connector (DLC). Check for DTCs. Is P20E8 the only DTC stored in the PCM memory?
    1. Yes – proceed to Step 2.
    1. No – this article does not apply. Refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual for normal diagnostics.
  1. Replace the reductant pump and heater assembly. Refer to Workshop Manual (WSM), Section 303-08.
  1. Clear all DTCs.
  1. Prime the new reductant pump and heater as follows:
    1. Disconnect the reductant pressure line from the reductant injector and place the line in a clean suitable container. Refer to WSM, Section 303-08.
    1. Using IDS, perform the selective catalytic reduction (SCR) visual leak check by selecting Toolbox > Powertrain > Service Functions > SCR system > SCR visual leak check. Run the test for two minutes.
    1. Connect the reductant pressure line to the reductant injector. Refer to WSM, Section 303-08.
    1. Perform SCR visual leak check to verify no leaks are present.
