Walker 210-1133 Air Charge Temperature Sensor

Air Charge Temperature Sensor Overview

The Walker 210-1133 air charge temperature sensor measures intake air temperature for the engine management system. It is a Sensor Only part for BMW M3 applications and supports accurate fuel delivery, cold-start performance, and emissions control.

Compatible With 2008-2013 BMW M3, Sensor Only. The Walker Products 210-1133 is built around a blade-pin, 2-terminal design with one female oblong connector for straightforward electrical integration.

Key Features

• Measures air temperature through resistance changes for engine control input.
• Sensor Only configuration for replacement of the sensing element.
• Blade pin terminals with a female oblong connector.
• Two-terminal electrical design with one connector.
• Supports fuel delivery accuracy, cold-start response, and emissions management.

Detailed Description

The Walker 210-1133 air charge temperature sensor provides the engine computer with temperature data used to calculate fuel delivery and manage combustion strategy. In BMW M3 applications, this sensor helps maintain consistent drivability by supplying the intake air temperature signal needed for efficient operation. Walker Products 210-1133 is a direct-fit sensor-only solution for the listed application and is identified by its blade-pin, female connector layout.

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

What It Helps Address

• Incorrect intake air temperature readings.
• Hard cold starts caused by poor sensor input.
• Reduced fuel control accuracy.
• Emission-related drivability concerns.
• Loss of engine response from faulty temperature data.

Installation Notes and Tips

Verify connector shape, terminal count, and terminal gender before installation. Match the existing sensor configuration to the vehicle harness and confirm the application by part number 210-1133. For BMW M3 fitment, use the listed Sensor Only configuration and inspect the connector for corrosion or damaged terminals during replacement.

Quality Assurance

Walker Products positions this sensor as a precision engine-management component for accurate temperature sensing and stable fuel calculation. Part number 210-1133 is engineered for the listed BMW M3 application.
