B144E on Lincoln

Position Sensor 2 of Tailgate/Liftgate

Minor1 Lincoln model affectedSystem: Body

B144E on Lincoln vehicles indicates position sensor 2 of tailgate/liftgate. Au7o has documented this code across 1 Lincoln model — most commonly on Aviator. 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.

Common Causes of B144E

  • •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  • •Outdated rear gate trunk module (RGTM) software falsely sensing the liftgate ajar — reprogramming is the first step on affected 2020 Explorer/Aviator builds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

  • Power-Liftgate Faults - Apply Ford SSM Symptom Split Before Parts2020-2022

    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.

On Lincoln specifically, this code is documented across 1 model.
