B144E on Lincoln: How to Diagnose & Fix
Position Sensor 2 of Tailgate/Liftgate

B144E on Lincoln by model: symptoms, diagnosis and fix
Ford documents several distinct Aviator power-liftgate conditions. On some 2020-2022 vehicles, failure only through hands-free intelligent access or the outside handle while doors are locked can result from a poor connection at rear-keyless-entry connector C4332 below the striker (SSM 50810). Some 2020-2021 inoperative liftgates can involve RGTM software (SSM 49914). Early 2020 vehicles built on or before February 17, 2020, can partially open or trigger a false anti-theft alarm with B144D, B144E, B1555, or B1556 from RGTM software (SSM 49015). These bulletins do not diagnose every liftgate fault.
Common Symptoms
- Hands-free or outside-handle opening fails while doors are locked
- Power liftgate is inoperative
- Early-build liftgate opens only partially
- False anti-theft alarm with liftgate-ajar sensing
How to Fix
Record which inputs fail, door-lock state, build date, movement, latch behavior, warnings, and RGTM DTCs. For the SSM 50810 symptom, inspect connector C4332 for connection, terminal, and pin-fit problems. For a matching SSM 49914 or 49015 software condition, use the latest Ford diagnostic software to reprogram the RGTM. If the symptom does not match, continue Workshop Manual diagnosis of power, grounds, switches, latch, position sensing, struts, wiring, and obstruction detection before selecting a part. This record intentionally has no commerce link.
Owner tips & cautions
- TipTest each input with the doors locked and unlocked and save the RGTM scan; input-specific behavior separates connector, software, and mechanical paths.
- WarningDo not buy a latch, strut, motor, or RGTM from a generic no-open symptom; Ford's SSMs first require a specific symptom/build/DTC match.

Frequently asked questions
What does B144E mean on a Lincoln?
B144E stands for "Position Sensor 2 of Tailgate/Liftgate." A Ford/Lincoln-specific body code stored by the power liftgate system (rear gate trunk module, RGTM, or liftgate control module). It reports a fault in the second position sensor that tracks how far the tailgate/liftgate has traveled, which on many of these vehicles is built into the power strut or motor assembly. Typical symptoms are a liftgate that only opens partway, stops or reverses on its own, refuses to run in power mode, or a false 'liftgate ajar' indication that can also trigger the anti-theft alarm. Ford issued a service message for 2020 Explorer and Aviator models where B144E — along with B144D, B1555, and B1556 — was caused by RGTM software improperly sensing the liftgate ajar, corrected by reprogramming rather than parts. On Lincoln it is documented across 1 model: Aviator.
What are the most common causes of B144E?
The most common causes of B144E are: Failed position sensor inside the power liftgate strut or motor assembly (assembly replacement), Outdated rear gate trunk module (RGTM) software falsely sensing the liftgate ajar — reprogramming is the first step on affected 2020 Explorer/Aviator builds, Damaged or chafed wiring in the liftgate harness where it flexes at the hinge, Corroded or loose strut/motor connector, often from water intrusion, Failed liftgate motor or drive unit logged alongside the sensor code, Faulty rear gate trunk module / liftgate control module. The specific cause varies by vehicle.
How much does it cost to fix B144E on a Lincoln?
Repair costs vary widely with the root cause and Lincoln model; each issue on this page carries its own estimate where one is published.
