In 90 percent of the cases, the problem of incorrect readings of the flight-temperature in Hyundai Tuccas is related to the failure of the outdoor air sensor, which has a significant impact on climate control. Frequently, problems occur during the cold time of the year. In this case, the cause may be:
Contamination, we need to clear the hull of the thermostat. This can be done with a thick brush to draw and a WD-40 cartridge, without dismantling the sensor. Dust the grease through the holes in the central bars of the front bumper, wait a few minutes and then wipe the dirt with the brush by periodically rinting it with water until it is completely cleaned.
Acidification of contacts-due to poor sealing into the connector, moisture and reagents are released and the terminals are oxidized over time. Therefore, if a malfunction occurs, they should be inspected and, if necessary, cleaned. According to the service manial, the front bumper must be removed for access to the sensor, but many owners are limited to the removal of the duster. This requires a certain level of skill and, preferably, a hole.
Low temperatures-a frequent denial of severe frosts and starts to work with warming. To speed up the process, you can put the car overnight into a warm garage or parking. In rare cases, the fault of the wet is the mechanical damage to the sensor's electrical circuit. In order to determine the location at which a break or closure occurred, they must be "ringed". But sometimes it's a visual inspection. If the recommendations did not resolve the problem, the sensor is not likely to be a problem and needs to be replaced.
Hyundai Tucson has two types of outdoor air sensors:
96985-2D700 for vehicles with Doowong cooling system;
96985-2D000-for cars with an Halla system.
It's best to pick up the VIN sensor. It will be necessary to remove the front bumper to replace it.
