Ambient temperature sensors take outside temperature measurements and transmit this data to the electronic control unit which, based on these readings, adjusts the air conditioning and heating systems as necessary.
5 tips on maintaining and replacing ambient temperature sensors
- The ambient temperature sensor doesn’t have a defined service life, therefore, it only needs to be replaced when it stops working.
- Incorrect information on the display isn’t always the result of faulty ambient temperature sensors. Readings can be too high if the device is exposed to direct sunlight. This can happen when a vehicle gets stuck in traffic. In winter the readings from the device can be too low if snow gets on the sensor.
- Find where the device is located, by checking your vehicle’s technical handbook, before you start testing or replacing the part. The device can be placed inside the wing mirror or in the bumper.
- Depending on the location of the sensor access to it can be restricted. It might be necessary to dismantle the door sill plates or front bumper grille.
- Before you remove the part, remove the negative terminal from the battery.
Common problems with ambient temperature sensors - causes and symptoms
- Mechanical damage to the mounting seat. This can sometimes happen when the car is used during heavy rain or strong winds. The device becomes detached causing failures in the functioning of the air conditioning or heating systems. An indication of this problem is that there are no readings displayed.
- Contact oxidation. This can be the result of the constant exposure to moisture which is worsened by the sensor’s close position to the road surface. A symptom of this issue is incorrect readings, for example, those that are much lower than the actual temperature. In some cases, the sensor doesn’t transmit any information.
- Housing leakage. The cause is an impact to the sensor, which could occur when the vehicle is driven off-road, for example. In the case of that defect, readings that are shown on the dashboard are incorrect.
