P273EGear Shift Control Module A Over Temperature
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
