P273E is a condition code: the gear shift control module A – the shift-by-wire selector unit – reports that its internal temperature exceeds the safe limit. No manufacturer documents P273E or its threshold publicly. Heat in such a unit can come from outside, for example a console exposed to strong sun or a module mounted near the exhaust tunnel, or from inside, when driver stages for lock solenoids, motors or illumination draw too much current. Because a hot module may give wrong position data, it typically reduces its functions; the vehicle may refuse range changes or hold Park until the unit cools. A code that returns at normal temperatures suggests an internal defect, while one tied to heat waves points to cooling or mounting.

Likely causes

Internal fault or overloaded output stage in the selector module
High ambient or radiant heat at the module location
Shorted lock solenoid or actuator driven by the module

Symptoms

  • Selector warning, functions limited
  • Range changes refused until the module cools
