ISSUE
Some 2009 Escape and Mariner vehicles equipped with a 6F35 transmissions built before 10/6/2008 may exhibit a no crank condition and/or diagnostic trouble codes (DTCs) P0706, P0707, P1702 caused by the output shaft speed (OSS) sensor wire pinched between the main control and transmission case or an intermittently shorted Transmission Range (TR) sensor.
ACTION
Follow Service Procedure steps to correct condition.
SERVICE PROCEDURE
NOTE
TR CODE DTC'S MAY BE A RESULT OF POOR COMMON POWER AND/OR GROUND CIRCUIT SHARED BETWEEN THE TR SENSOR, OSS SENSOR AND TURBINE SHAFT SPEED (TSS) SENSOR.
1. Follow Workshop Manual (WSM), Section 307-01A pin point test (PPT) D through to Step 9.
2. If the cause for the condition has not been found by the end of step 9 in PPT D, unplug the OSS connector from the solenoid body lead frame.
3. Check the resistance between the transmission case and each of the three (3) OSS sensor wires one at a time. If any one of the three (3) OSS sensor wires are shorted to ground (transmission case), less than 5 ohms, replace the OSS sensor. Follow WSM, Section 307-01A, for replacing the OSS. Being very careful not to pinch the OSS sensor wires during the installation of the main control.
4. If the OSS sensor wires are not shorted to ground, replace only the TR sensor following WSM, Section 307-01A.
