Walker 210-1134 Air Charge Temperature Sensor

Air Charge Temperature Sensor for BMW Diesel Applications

Walker 210-1134 is a sensor-only air charge temperature sensor built for precise intake air temperature measurement in select BMW diesel applications. By reporting temperature changes through resistance variation, it helps the engine computer calculate fuel delivery more accurately for smoother operation and efficient combustion.

Compatible With 2014-2018 BMW 328d, 2014-2018 BMW 328d xDrive, 2018 BMW 540d xDrive, 2014-2018 BMW X5, 2015-2017 BMW X3, 2014-2016 BMW 535d, 2014-2016 BMW 535d xDrive, and 2015 BMW 740Ld xDrive. Walker Sensor Only line focuses on the sensing element itself for applications that call for a direct sensor replacement.

Key Features

• Air charge temperature sensor for engine management systems
• Sensor-only design
• 1 female connector with oblong shape
• 2 male terminals with pin-style terminal type
• Built for select BMW diesel fitments
• Part number 210-1134 for accurate ordering and lookup

How It Works

The Walker Products air charge temperature sensor measures incoming air temperature and sends that data to the vehicle computer. That information supports fuel calculation, cold-start strategy, emissions control, and overall drivability. For BMW 328d, X5, and related diesel models, accurate intake air temperature input is important for consistent engine response and efficient operation.

Common Issues It May Address

• Incorrect intake air temperature readings
• Poor cold-start performance
• Reduced fuel efficiency from inaccurate air temperature data
• Rough idle or inconsistent engine response
• Check engine light related to air temperature sensor faults

Installation Notes

Verify connector style, terminal count, and sensor location before installation. This part uses a female connector, oblong connector shape, and 2-pin terminal layout, so matching the original connector is important. Confirm the vehicle application by year, make, and model before replacing the sensor. Part number 210-1134 should be matched to the original unit when ordering.

Quality Assurance

Walker Products is known for engine management components that support accurate sensor input and dependable OE-style service. This air charge temperature sensor is engineered for the listed BMW applications and built to support precise temperature measurement for the engine control system.
