Service Procedure
1. Connect the Ford Integrated Diagnostic System (IDS) or Ford J2534 Diagnostic Software (FJDS) to the data
link connector (DLC). Check for DTCs P0263, P0266, P0269, P0272, P0275, P0278, P0281, P0284, P2B11,
P2B13, P2B15, P2B17, P2B19, P2B1B, P2B1D and/or P2B1F.
2. Are one or more DTCs stored in PCM memory and does the vehicle exhibit a fuel knock type noise at idle?
(1). Yes - proceed to Step 3.
(2). No - this article does not apply. Refer to the Powertrain Control/Emissions Diagnosis (PC/ED) Manual for
normal diagnostics.
3. Using IDS or FJDS, enter PCM datalogger and select the following parameter identifications (PIDs):
(1). ECT1 (Temp)
(2). EGRVPDES#
(3). EOT
(4). RPMDSD#
(5). VGTDC#

4. Using active command, select RPM# PID and increase engine speed to 1500 RPM for two minutes.
5. Hold engine speed at 1500 RPM and command EGRVPDES# to lowest value and VGTDC close to about
60% to ensure Engine Coolant Temperature (ECT)1 and Engine Oil Temperature (EOT) are above 80°C (176°
F). Once ECT1 and EOT reach 80°C (176°F), return engine speed to idle. Release command from the other
parameters.
6. Perform the manual injector balance test under toolbox > powertrain > power balance. Does the noise go
away when running the manual injector balance test?
(1). Yes - proceed to Step 7.
(2). No - this article does not apply. Refer to PC/ED Manual for normal diagnostics.
7. Using IDS or FJDS, select toolbox > powertrain > service functions. Reset the following specified functions:
(1). Fuel System – High Pressure Side
(2). Min. Fuel Mass Adaptation - All Cylinders
(3). Crankshaft Position Sensor
8. Clear all DTCs.
9. Reprogram the PCM using IDS or FJDS release 107.06 or higher. Make sure you are connected to the
internet when entering module programming to obtain the latest updates. Calibration files may also be obtained
at www.motorcraftservice.com.
(1). NOTE: ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE
TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE
TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE
STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING
PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL
DAYS.
