Walker 210-91045 Ambient Air Temperature Sensor

Walker Ambient Air Temperature Sensor

Walker Products Part Number 210-91045 is an OE replacement ambient air temperature sensor built for vehicles that rely on accurate outside-air readings for climate control and display functions. It uses a plastic housing, a pin terminal design, and an oblong connector shape for direct integration with the factory wiring on supported Chrysler, Dodge, Jeep, and Mitsubishi applications.

Walker Full Service Kit 210-91045 is engineered for precise resistance values and stable signal output across a wide temperature range. It is a direct-fit solution for Chrysler 300, Dodge Charger, Ram 1500, Jeep Grand Cherokee, and other listed applications where the ambient sensor feeds HVAC blend door operation, automatic climate control logic, and temperature display functions.

Product Details

Walker Products Full Service Kit line focuses on service-ready replacement components that match original equipment fit and electrical connection requirements. This ambient air temperature sensor is built with high-quality thermistor elements and a sealed housing to maintain consistent output in road salt, moisture, vibration, heat, and cold. For vehicles such as the Dodge Ram 2500, Jeep Liberty, and Chrysler Pacifica, accurate ambient data is essential for proper climate control response and reliable temperature display operation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Sensor Can Address

• Incorrect outside temperature display
• HVAC system reading ambient air temperature inaccurately
• Automatic climate control reacting improperly to outside conditions
• Blend door operation affected by faulty ambient input
• Idle speed or other ambient-dependent functions receiving bad temperature data

Installation Notes and Tips

Verify connector shape, terminal style, and vehicle application before installation. This sensor is designed to connect directly to the factory harness and mount at OE locations on supported vehicles. Confirm the replacement matches the original sensor configuration on your Chrysler, Dodge, Jeep, or Mitsubishi model before final assembly.

Quality Assurance

Walker Products manufactures this sensor as an OE replacement component with sealed construction and thermistor-based signal control for consistent performance in demanding driving conditions.
