The outside air temperature sensor, although located at the front of the car behind the radiator grille in a place protected from sunlight and ventilated, is subject to factors such as warm air from the engine and radiation from hot asphalt. Therefore, its readings may sometimes be somewhat overestimated, especially after a long period of standing in traffic jams. The outside air temperature readings can be considered correct when driving at a speed of at least 40 km / h for at least 10 minutes.
If it is necessary to replace the sensor, perform the following operations.
1. Disconnect the wire from the negative terminal of the battery.
2. Remove the engine splash guard (see Removing and installing mudguard and engine crankcase protection).
3. Squeeze the retainer and disconnect the sensor wiring harness connector.
4. Press the spring holder…
5….and remove the sensor.
6. Install the new outside air temperature sensor in the reverse order of removal.
