Service bulletin SSM 47765

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2013-2018 C-MAX, 2013-2019 Fusion Energi, and 2017-2019 Fusion/MKZ Hybrid vehicles may exhibit an illuminated MIL with diagnostic trouble code (DTC) P04B5. This may be due to inadvertent actuation of the fuel door release button by the customer when exiting the vehicle. If the fuel filler door is not fully closed after a refueling event or the fuel filler door is open from erroneously pressing the fuel door release button, a message displays during the third drive cycle to indicate the fuel filler door is not closed and the DTC sets. Before performing Workshop Manual (WSM) diagnosis, consult the customer about the potential for accidental fuel door actuation and explain the need to fully latch the fuel door after every refueling event. Malfunction Indicator Lamp will turn off after (3) drive cycles with fuel filler door closed.

SSM 54504	2026-01-21. Service bulletin. Some 2016-2017 Edge/MKX, 2017 Continental/Fusion/MKZ vehicles equipped with a 2.7L or 3.0L EcoBoost engine and built on 1-Apr-2016 and through 1-Jan-2017 may exhibit white or blue smoke from the exhaust, rough idle in neutral or park at normal operating temperature or after a hot restart. The vehicle may also exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0300, P0301, P0302, P0303, P0304, P0305, P0306 and/or P0316, P0524 and/or P06DD with excessive oil consumption. Oil consumption may be 1 Liter (1 quart) in less than 4,800 km (3,000 miles). This may be due to the valve guides. To correct the condition replace the cylinder heads. During service and repair, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in timing gear failure and engine damage. Replacement of the bolt is critical to the repair. The bolt requires a 4 stage torque procedure. Hold the pulley using a universal holding tool OTC 4754 or equivalent. Refer to Workshop Manual, Section 303-01. The bolt torque procedure can be

TSB 25-2395	2025-09-03. Service bulletin. This article supersedes TSB 24-2345 to update the Service Procedure. Some of the vehicles listed in the Model statement above may exhibit an oil leak from the engine oil pan RTV seal. This may be due to a lack of RTV adhesion.
TSB160045	2021-12-20. Service bulletin. 2.0L Ecoboost - Fuel odor
TSB160001	2021-12-20. Service bulletin. 49 CFR Part 579.5 Monthly Communications - March 2016 Air bag warning light illuminated with diagnostic trouble code (DTC) B141B and/or B141C
LTR3756	2021-12-20. Service bulletin. 49 CFR Part 579.5 Monthly Communications - January 2016
SSM 48397	2020-01-08. Service bulletin. Some 2013-2015 Fusion/MKZ/Escape/MKC with a 1.6L GTDI, 1.5L GTDI, or 2.0L GTDI may exhibit a lack of power, loss of power, or stall when placed in gear with DTCs P00C6, P0087, P008A, P008B, P018C, or P018D. If normal diagnosis leads to a biased or failed Fuel Low Pressure (FLP) sensor, the sensor is available without the need to order the entire fuel line assembly. The FLP sensor, located on the fuel supply line to the high pressure pump, provides the low side fuel pressure input to the PCM so the Fuel Driver Module can be controlled accordingly. The FLP PID can be viewed in the Datalogger and then compared to a manual pressure gauge per pinpoint test HC in the PCED to validate the sensor is working properly. The Fusion/MKZ catalog has been updated to show the sensor availability.
SSM 47737	2019-03-04. Service bulletin. Some 2017-2019 MKZ vehicles equipped with a 2.0 HEV engine may exhibit a fuel filler door unable to be opened or closed with or without an illuminated malfunction indicator (MIL) and DTC P04B5. This may occur when the fuel door is pressed or obstructed while the fuel door release latch is operating. If the fuel filler door is unable to be closed, a message displays during the third drive cycle and the DTC P04B5 will set. Before performing Workshop Manual (WSM) diagnosis, reset the system by pressing the fuel filler door release switch and wait 12 seconds for reset. The fuel door release latch should be heard when the motor is in motion. Review fuel filler door for locking tab operation. If the fuel filler door is operating properly, it should not be replaced. Advise the customer about the correct operation of the fuel filler door.
SSM 47090	2018-05-14. Service bulletin. Some 2017-2018 Energi and Hybrid vehicles may exhibit a fuel door opening delay longer than 15 sec or unable to open condition without refueling system or fuel door related DTCs. This condition may be due to the high pressure fuel tank pressure transducer (HPFTPT) functionality. Check the HPFTPT after opening the fuel door by releasing the mechanical lever located in the trunk. Install supplemental refueling adaptor in the vehicle to open the capless fuel tank filler pipe. During key on engine off (KOEO) condition check if the fuel tank pressure transducer (FTPT) voltage is between 1.4 1.54 V at atmospheric pressure in the tank. If the voltage is within the range, FTPT is functioning as intended. Check the fuel vapor vent valve (FVVV), also called refueling valve, integrity by following Workshop Manual (WSM), Section 310-00.
SSM 46090	2017-08-01. Service bulletin. Some 2017 Fusion vehicles built on or before 20-Sep-2016 may exhibit a slow to update fuel gauge, erratic fuel gauge reading, and/or distance to empty (DTE) concern after a refueling event with no diagnostic trouble codes (DTCs) stored in powertrain control module (PCM). Do not attempt a repair at this time. Engineering is currently investigating a fix. To assist with the investigation use the Report A Vehicle Concern link at the bottom of the Oasis report and submit a Global Concern Report (GCR). Continue to monitor OASIS for updates.
