Shell S-TEC 31217286 Ambient Air Temperature Sensor OEM

The Shell S-TEC 31217286 is an ambient air temperature sensor (also known as an outdoor temperature sensor) designed as a direct OEM replacement. This sensor monitors the outside air temperature and feeds precise data to the vehicle's climate control system, enabling automatic adjustment of interior cabin temperature for consistent driving comfort.

Key Features:

• Genuine OEM replacement — part number 31217286
• Measures and reports ambient outside air temperature to the climate control module
• Plug-and-play fitment with no complex modifications required
• Durable construction built to withstand under-vehicle temperature and environmental exposure
• Restores proper automatic climate control and A/C system function
• Available in driver (left) and passenger (right) positions

A faulty ambient air temperature sensor can cause the automatic climate control system to misread outside conditions, leading to improper A/C operation or inaccurate temperature display. Replacing a worn or failed sensor with OEM part number 31217286 restores accurate temperature monitoring and proper HVAC system performance.
