Rein Ambient Air Temperature Sensor

The Rein Ambient Air Temperature Sensor (also called an outside air temperature sensor or ambient temperature sensor) measures the temperature of the air outside the vehicle. It sends that reading to the climate control system and, on many applications, to the instrument cluster display.

Key Features:

• Replacement sensor for HVAC and outside temperature monitoring
• Helps the automatic climate control system keep cabin temperature accurate and consistent
• Supports reliable outside temperature readouts on the dash or driver information display
• Designed as a direct-fit replacement to restore original operation
• Rein is an aftermarket brand known for OE-style replacement parts for European and import vehicles

A failing ambient air temperature sensor can cause an incorrect or missing outside temperature reading and inconsistent automatic climate control performance. Replacing it helps restore normal HVAC operation and accurate temperature display.
