If the check engine light comes on in your MINI Cooper, it is advisable to pull over and stop driving immediately. Continuing to drive with the check engine light on may lead to permanent damage to your engine components. Once you have safely stopped, you can utilize an OBD II scan tool to retrieve the stored codes in the ECU. For instance, if you receive a code 2F1A, it indicates a problem with the temperature sensor. A faulty temperature sensor will not provide accurate information, usually due to the sensor malfunctioning when it breaks. In such a case, it is necessary to replace the sensor with a new one.
2f1a is an abbreviation that represents a fault in the minimum temperature sensor.
