Walker 210-1073 Air Charge Temperature Sensor

Air Charge Temperature Sensor for Audi and Volkswagen

Walker 210-1073 is a sensor-only air charge temperature sensor built for precise intake air temperature measurement in supported Audi and Volkswagen applications. By reporting accurate air temperature data to the engine computer, it helps the system calculate fuel delivery and maintain proper engine operation.

Walker Sensor Only products focus on the sensing element itself, making this part a direct replacement choice when the original air charge temperature sensor has failed or is reading out of range. Part number 210-1073 is used across a wide range of turbocharged and naturally managed engine applications in Audi A4, A4 Quattro, A5, A6, Q5, TT, TTS, A3, Q3, and Volkswagen GTI, Jetta, Passat, Tiguan, and related models.

Key Features

• Air charge temperature sensor for engine management systems
• Measures intake air temperature through resistance changes
• 2-terminal, pin-style design
• 1 female oval connector
• Male terminal gender for secure electrical connection
• Sensor-only configuration for replacement of the sensing element

Detailed Description

Walker 210-1073 is engineered to provide the engine control module with accurate air temperature input, which is used to determine fuel delivery and support efficient combustion. Correct temperature data is important for cold-start behavior, drivability, emissions control, and protection against improper fueling caused by a faulty sensor signal. This part number 210-1073 is a direct-fit style replacement for many Audi and Volkswagen models, including Audi A4, A4 Quattro, A5, A6, Q5, TT, TTS, A3, Q3, and Volkswagen CC, Eos, GTI, Jetta, Passat, Tiguan, Beetle, Golf R, and Tiguan Limited.

This part cross-references OE-style applications where the same air charge temperature sensor function is required for the listed vehicles.

What It Helps Solve

• Incorrect intake air temperature readings
• Hard cold starts or rough cold-start operation
• Poor fuel delivery caused by inaccurate sensor input
• Reduced engine performance from faulty air temperature data
• Emissions issues related to improper air/fuel calculation

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle fitment before installation. This sensor uses a 1-connector oval housing with 2 terminals, so matching the electrical connection is important for proper operation. Confirm the exact application by year, make, model, and any VIN break notes listed for 2003 Audi and Volkswagen vehicles.
