Publication Date: May 4, 2016

 

LINCOLN:

2016 MKX

 

ISSUE:

Some 2016 MKX vehicles equipped with a 3.7L Duratec engine and built on or before 4/21/2016 may exhibit an illuminated MIL with DTC P013C stored in the powertrain control module (PCM). This may be caused by improper sealing of the left side exhaust y-pipe flange due to weld splatter or exhaust pipe intrusion into the flange sealing surface.

 

ACTION:

Follow the Service Procedure steps to correct the condition.

 

SERVICE PROCEDURE

1. Use the Ford Integrated Diagnostic System (IDS) or equivalent scan tool to check for DTCs in the PCM. Is DTC P013C present?
   1. Yes – proceed to Step 2.
   1. No – this article does not apply. Refer to the Powertrain Controls and Emissions Diagnostics (PC/ED) manual for normal diagnostics.

1. Remove the exhaust y-pipe. Refer to Workshop Manual (WSM), Section 309-00.

1. Inspect the left side exhaust y-pipe flange sealing area that attaches to the left side catalytic converter for signs of weld slag and/or exhaust pipe intrusion into the flange sealing area. Are sign of weld slag and/or exhaust pipe intrusion present in the flange sealing area? (Figures 1-2)
   
   Figure 1 – 16-0078

   
   Figure 2 – 16-0078

   1. Yes – proceed to Step 4.
   1. No – proceed to Step 5.

1. Use a flat file or 60 grit sandpaper on an oscillating sander with a flat pad to remove the weld slag and/or exhaust pipe material protruding above the flange sealing surface.
   1. Removing too much material from the flange sealing surface may cause additional exhaust leaks.

1. Check for proper torque of the left side catalyst monitoring sensor (CMS). The CMS should be torqued to 48 Nm (35 lb-ft ).

1. Clean the exhaust y-pipe mounting flanges with a clean microfiber cloth and replace the exhaust y-pipe gaskets.

1. Reinstall the exhaust y-pipe. Refer to WSM, Section 309-00.

1. Clear DTCs from the PCM memory.
