Detailed Description

Walker 210-1065 is an OE replacement ambient air temperature sensor that measures outside air temperature and sends that data to the vehicle’s control systems. Accurate ambient readings support automatic climate control, temperature display functions, engine idle strategy, and HVAC blend door operation. This sensor uses a plastic body, oval connector shape, 2 terminals, and a female connector design with male blade terminals for direct harness connection. It is a practical replacement for Volkswagen Golf, Passat, Tiguan, and Jetta models listed in the fitment data.

This part cross-references Standard Ignition AX178 for the same application.

What It Helps Correct

• Incorrect outside temperature display
• HVAC temperature regulation errors
• Automatic climate control response issues
• Faulty ambient air signal input to vehicle systems
• Inconsistent blend door operation tied to temperature data

Installation Notes

Install using the factory mounting points and connect directly to the OE-style wiring harness. No wiring harness is included. Verify connector shape, terminal type, and fitment before installation on the vehicle.

Quality Assurance

Walker ambient air temperature sensors are built with sealed housings and thermistor-based sensing elements to maintain stable output in demanding driving conditions. The Sensor Only line focuses on direct replacement electrical components for OE-style service.
