Ford Diesel Down on Power
Some 2008-2010 Ford F-Super Duty vehicles equipped with a 6.4L diesel engine may exhibit a lack of power, MIL on, with DTCs P20E2, P20E3, P20E4, P2080, P2084, P242A, P242B, P0544 or P2031.
1. Monitor all continuous memory DTCs (CMDTCs) using the integrated diagnostic scan tool (IDS) or equivalent. Are any of the afore-noted DTCs present?
a. No… This bulletin does not apply. Refer to the powertrain control/emissions manual for further diagnosis.
b. Yes… Proceed to Step 2.
2. Replace the faulty exhaust gas temperature (EGT) sensor based on the DTC present using the EGT replacement procedure:
a. Disconnect the faulty EGT sensor electrical connector.
b. Disconnecting an EGT sensor with the key in the on position may force the vehicle into a one hour no-crank lock-out.
c. Cut the EGT sensor connector wire leads just above the sensor.
d. Apply heat to the EGT sensor mounting boss to aid in sensor removal.
e. Use a 13 mm, six-point deep-well socket to remove the sensor from the exhaust.
f. Apply a small amount of Motorcraft High Temperature Nickel Anti-Seize lubricant to the threads of the new sensor.
g. Install the EGT sensor and torque to 22 ft.-lbs.
