SSM 522442024-02-14. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2021-2023 F-150 vehicles equipped with a 3.5L PowerBoost hybrid engine, 2020-2023 Explorer vehicles equipped with a 3.3L hybrid engine and 2020-2023 Aviator vehicles equipped with a 3.0L hybrid engine may exhibit a malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0A1E stored in the powertrain control module (PCM) and auto start/stop disabled. This may be due to a loose wiring connection to the belt integrated starter generator (BISG). The Workshop Manual (WSM) has recently been updated to provide new direction for DTC P0A1E. Refer to the WSM, Section 303-06 Starting System, Diagnosis and Testing, Starting System for applicable diagnosis.
SSM 522182024-02-06. Service bulletin. ENGINE AND ENGINE COOLING. Some 2021-2023 F-150 non-Lightning vehicles may exhibit reduced power and/or lack of acceleration above 4000 revolutions per minute (RPM) and/or not being able to shift above 4000 RPM. This may be due to the missing retainers (service part number W714040-S300) from the air cleaner intake. Prior to performing other diagnostics, inspect the air cleaner intake to determine if the retainers are present and fully seated. If the retainers are not present, install as necessary. Refer to the Workshop Manual (WSM), Section 303-12C Intake Air Distribution and Filtering - 3.5L EcoBoost (BM), Removal and Installation, Air Cleaner, Removal, Step 4. If the retainers are present, or the missing retainers were replaced and the symptom is still present, refer to the WSM for additional diagnostics. For claiming, use causal part 9C675 and applicable labor operations in Section 06 of the Service Labor Time Standards (SLTS) Manual.

Refer to the Workshop Manual (WSM), Section 412-00 Climate Control System - General Information, Diagnosis and Testing, Climate Control System - Electric, Vehicles With: Dual Automatic Temperature Control (DATC) and perform Pinpoint Test AK: P2DA6:00. In Step AK4, if the ECT2 sensor PID value is greater than 70 degrees Celsius (158 degrees Fahrenheit), this condition may be due to the software level of the SOBDMC. This condition does not affect vehicle operation or durability and no additional diagnosis or service is required for this condition at this time. Engineering is working on a solution that is expected in Q2 2024. Monitor OASIS for additional information and schedule service appointments once the repair becomes available.
