Error P0073 means that the car's control unit is receiving a signal that is too high from the ambient air temperature sensor. In simple words, the system "thinks" it’s very hot outside, even if it's not.
This is a common issue, especially after accidents, winter driving, engine washes, or in older cars. Seen often in Ford, Opel, Hyundai, Peugeot, VW, and others.
This error is not critical. It doesn’t affect driving safety or the engine, but it may affect the accuracy of climate control and temperature readings.
In most cases, replacing the sensor solves the issue. Also check and repair the wiring or connector if needed. Clear the error code using a scanner after the repair.
