Walker Air Charge Temperature Sensor for BMW

The Walker Products Air Charge Temperature Sensor helps the engine computer read incoming air temperature so fuel delivery can be adjusted with greater precision. This Walker Sensor Only part, part number 210-1178, is a direct-fit service component for select BMW diesel applications, including BMW X5 and BMW 335d models.

Key Features

• Measures intake air temperature through resistance changes for accurate engine management input
• Female connector with oval shape for a secure electrical interface
• 2 male terminals with pin-style terminal design
• Sensor-only replacement for servicing the temperature sensing element
• Supports cold-start performance, fuel control, and emissions management

Product Details

Walker 210-1178 is an air charge temperature sensor built for vehicles that rely on precise intake air data to manage combustion. By reporting air temperature to the onboard computer, it helps the system calculate fuel delivery and maintain proper engine operation. This part is listed for 2009-2013 BMW X5 and 2009-2011 BMW 335d applications, making it a focused replacement for diesel engine management service. If you are searching for a BMW X5 air charge temperature sensor or a BMW 335d intake air temperature sensor, Walker 210-1178 is the correct service part to review.

Walker Products positions this Sensor Only line around accurate signal delivery and dependable engine control input. The design supports the needs of modern diesel management systems where intake air temperature affects starting behavior, drivability, fuel efficiency, and emissions performance. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Incorrect air temperature readings sent to the engine computer
• Hard cold starts caused by poor intake air temperature input
• Reduced fuel efficiency from inaccurate fuel calculation
• Loss of engine response tied to faulty sensor data
• Emissions-related drivability concerns from unstable air charge readings

Installation Notes and Tips

Verify connector shape, terminal count, and sensor location before installation. This part uses a female oval connector with two male terminals, so matching the electrical connection is important for proper fitment. Confirm the vehicle application against the listed BMW X5 and BMW 335d coverage before replacing the original sensor.

Quality Assurance

Walker Products is known for engine management components that focus on accurate signal output and OE-style service replacement. Part number 210-1178 is built for the listed BMW applications and supports consistent sensor performance in intake air temperature monitoring.
