Walker 210-1140 Air Charge Temperature Sensor

Air Charge Temperature Sensor for Mercedes-Benz

Walker 210-1140 is a Sensor Only air charge temperature sensor built for Mercedes-Benz applications that rely on accurate intake air temperature data for engine management. By reporting temperature changes through resistance, it helps the ECU calculate fuel delivery, support cold-start operation, and maintain efficient combustion.

Compatible With Mercedes-Benz AMG GT 63, G550, G63 AMG, GLE63 AMG S, GLS580, Maybach GLS600, S580, and other listed models across 2011-2024 applications.

Key Features

• Air charge temperature sensor for precise intake air temperature measurement
• Walker Sensor Only line for direct sensor replacement needs
• Blade pin terminal type with 1 oblong female connector
• 2 male terminals for secure electrical connection
• Supports engine control strategies that rely on accurate air temperature input
• Part number 210-1140 for easy identification

How It Works

The Walker Products air charge temperature sensor measures incoming air temperature and sends that information to the vehicle’s onboard computer. That data is used to refine fuel delivery, improve cold-start behavior, and help the engine management system maintain proper performance and emissions control. For Mercedes-Benz models such as the C43 AMG, E63 AMG S, and Sprinter 2500, accurate temperature input is important for consistent drivability and efficient operation.

Common Issues This Sensor Can Help Address

• Incorrect air temperature readings in the engine management system
• Rough cold starts or inconsistent startup behavior
• Poor fuel delivery caused by inaccurate intake air data
• Reduced engine efficiency from faulty sensor input
• Emissions-related faults tied to temperature signal errors

Installation Notes and Tips

Verify connector shape, terminal type, and terminal count before installation. This part uses a blade pin terminal design with one oblong female connector and two male terminals. Confirm the vehicle application by year, make, and model before ordering, especially on Mercedes-Benz AMG, GLE, GLS, S-Class, and Sprinter platforms. Part number 210-1140 should be matched to the existing sensor specification during replacement.

Quality Assurance

Walker Products is known for engine management components that focus on accurate signal delivery and OE-style fitment expectations. This Sensor Only air charge temperature sensor is built for the listed Mercedes-Benz applications and supports dependable replacement service for temperature-based engine control.
