ISSUE
Some 2006-2008 Explorer, Mountaineer and Sport Trac vehicles and equipped with 4.6L 3-V engines may exhibit:
^ Diagnostic trouble code (DTC) P0196 - engine oil temperature (EOT) sensor range/performance during ice/snow driving conditions.
^ Idle speed dropping below specification, hesitation or loss of RPM with no DTCs stored in the Powertrain Control Module (PCM).
^ Cruise control surge at approximately 50-60 MPH (80-97 Km/h) in hilly regions Only applies to vehicles operated in altitudes above 5000 feet (1.52
km).
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
If normal Powertrain Controls/Emissions Diagnosis (PC/ED) diagnostics do not resolve the above vehicle concerns, reprogram the PCM and
Transmission Control Module (1CM) to the latest calibration using IDS release 63.08 and higher. This new calibration is not included in the VCM
2009.9 DVD. Calibration files may also be obtained at the website.
NOTE
VEHICLES EQUIPPED WITH A PCM AND TCM, REQUIRE A COORDINATED REPROGRAMMING.
THIS COORDINATED REPROGRAMMING PROCEDURE MUST BE FOLLOWED EXACTLY AS OUTLINED BY THE INTERGRATED
DIAGNOSTIC SYSTEM (IDS). FAILURE TO FOLLOW THE KEY CYCLE PROCEDURE WITHOUT WAITING FOR THE IDS PROMPTS,
WILL CAUSE THE COORDINATED REPROGRAMMING TO FAIL. THE PCM WILL BE UPDATED BUT THE 1CM WILL NOT BE UPDATED
AND THE NEW FILES WILL NOT BE INSTALLED. IT IS CRITICAL TO FOLLOW THE IDS PROMPTS.
1. Install IDS / portable diagnostic software (PDS) or equivalent and identify (ID) the vehicle.
2. Update the PCM and TCM calibration using IDS release 63.08 and higher. This new calibration is not included in the VCM 2009.9 DVD.
Calibration files may also be obtained at the website. Since the TCM cannot be independently reprogrammed, reprogram the PCM to ensure that
engine and transmission calibrations are updated to the latest level simultaneously.
3. Clear TCM keep alive memory (KAM) and adaptive tables.
a. Using IDS:
(1) Open Toolbox.
(2) Choose Powertrain.
(3) Choose Reset KAM.
(4) Then Choose TCM.
b. Using PDS:
(1) Choose all Tests and Calibrations.
