Walker 210-1079 Air Charge Temperature Sensor

Air Charge Temperature Sensor for Engine Management

Walker 210-1079 is a Sensor Only air charge temperature sensor built for precise intake air temperature measurement. It uses resistance changes to report air temperature to the engine computer, helping the system calculate fuel delivery more accurately for smoother operation and better fuel control.

Compatible With select Audi and BMW applications, including 2003 Audi RS6 and 1997-1999 Audi A8 models, plus 1995 BMW 325i, 525i, 540i, 740i, 840Ci, and M3 applications. The Walker Sensor Only line focuses on the sensing element itself for direct replacement needs where the original sensor design is retained.

Key Features

• Walker 210-1079 air charge temperature sensor for engine management systems
• Measures intake air temperature through resistance-based signal output
• Supports fuel delivery calculations, cold-start performance, and emissions control
• Sensor Only design for applications that use the original sensor configuration
• Connector details: 1 connector, rectangle shape, female connector gender, 2 terminals, spade terminal type, male terminal gender

Detailed Description

This air charge temperature sensor helps the engine control module monitor incoming air temperature so it can adjust fueling and operating strategy based on real-time conditions. Accurate intake air data is important for drivability, fuel efficiency, engine protection, and maintaining proper emissions performance. Walker 210-1079 is a practical replacement choice for Audi RS6, Audi A8, Audi A8 Quattro, and multiple 1995 BMW models where the original sensor-only configuration is used.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Incorrect air temperature input to the engine computer
• Hard cold starts or inconsistent warm-up behavior
• Reduced fuel control accuracy under changing intake conditions
• Driveability issues tied to faulty intake air temperature sensing
• Emissions concerns caused by inaccurate sensor readings

Installation Notes and Tips

Verify the connector style, terminal count, and sensor location before installation. This unit uses a rectangle connector with 1 connector, 2 terminals, female connector gender, and male spade terminals. Confirm the vehicle uses a Sensor Only configuration and match the original mounting and electrical connection before replacement.
