ISSUE
Some 2009-2010 Escape, Mariner, 2010 Fusion and Milan vehicles equipped with a 6F35 automatic transmissions and built on or before 11/25/2009
may exhibit diagnostic trouble codes (DTCs) P0720 or P0722 DTC harsh engagement or shifts or starts in 5th gear from a stop. These conditions may be
caused by an open circuit in the output shaft speed (OSS) sensor or the main control lead frame connector.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Check the condition of the transmission fluid.
a. If the fluid dose not smell burnt, continue to Step 2 and follow the repair procedure to diagnose the OSS circuit
b. If fluid smells burnt, follow normal Work Shop Manual (WSM) diagnosis to repair.
2. Follow WSM, Section 307-01A for Escape and Mariner or 307-01B for Fusion and Milan. Perform pin point test (PPT) steps C through C7.
a. If instructed to replace the OSS sensor in PPT step C7, proceed to Step 3.
b. If the PPT does not lead to replacing the OSS, this procedure does not apply and proceed with normal diagnostics.
3. Check the build date on the lead frame. (Figure 1) The lead frame build date is a Julian date. The first two numbers are the year (09) and the next
three numbers are the day of the year.
a. If the build date matches one from the table, replace the lead frame and the OSS sensor. (Table 1)
(1) When replacing the lead frame, inspect the build date on the new part. Do not use a lead frame with a build date listed in the table.
b. If the lead frame build date does not match one from the table, only replace the OSS sensor.
