The Toyota Tundra's ambient temperature sensor, positioned beneath the front grille on the driver's side below and to the left of the headlight, plays a crucial role in capturing the outside temperature and transmitting it to the vehicle's computer. It is essential that the sensor is securely connected to a cable. If there are interruptions or inaccuracies in the external temperature readings, this could impact your ability to maintain the cabin at your preferred temperature settings. The HVAC system relies on the ambient sensor to determine the appropriate amount of hot or cold air to circulate within the interior. Factors such as dirt, debris, or damage can lead to the degradation or obstruction of the ATS. The estimated cost to replace the sensor, including parts and labor, falls between $85 and $100.
The temperature sensor of a Toyota Tundra can be found beneath the front hood, close to the car's lower section.
