Walker 210-1130 Air Charge Temperature Sensor

Air Charge Temperature Sensor for Turbocharged GM Trucks

Walker 210-1130 is a sensor-only air charge temperature sensor that measures intake air temperature through resistance changes and sends that data to the engine computer. That input helps the PCM calculate fuel delivery more accurately, supporting smoother operation, better cold-start behavior, and cleaner emissions control.

Key Features

• Air charge temperature sensor for turbocharger applications
• Sensor-only design with plug-in mounting type
• 1 female rectangle connector with 2 male blade terminals
• Direct-fit electrical interface for service replacement
• Walker 210-1130 part number for catalog matching

Detailed Description

Walker Sensor Only 210-1130 is built for turbocharger-mounted air charge temperature sensing on select Chevrolet and GMC diesel applications. It provides the temperature signal the engine management system uses to adjust fueling, helping maintain proper air-fuel balance under changing boost and intake conditions. This part cross-references Standard Ignition TX266 for the same application. The Walker 210-1130 is a practical replacement when the original sensor has failed, the signal is erratic, or the engine computer is receiving inaccurate intake air temperature data.

Compatible With 2011-2016 Chevrolet Express 2500, turbocharger location; 2011-2016 Chevrolet Express 3500, turbocharger location; 2011-2012 and 2015-2016 Chevrolet Silverado 2500 HD, turbocharger location; 2011-2012 and 2015-2016 Chevrolet Silverado 3500 HD, turbocharger location; 2011-2016 GMC Savana 2500, turbocharger location; 2011-2016 GMC Savana 3500, turbocharger location; 2011-2012 and 2015-2016 GMC Sierra 2500 HD, turbocharger location; and 2011-2012 and 2015-2016 GMC Sierra 3500 HD, turbocharger location.

What It Helps Address

• Incorrect intake air temperature readings
• Hard cold starts caused by faulty sensor input
• Reduced fuel control accuracy under boost
• Check engine light concerns related to air charge temperature data
• Rough running or drivability issues tied to sensor failure

Installation Notes and Tips

Verify the connector shape, terminal count, and turbocharger mounting location before installation. This unit uses a plug-in mounting style with a single rectangular female connector and blade terminals, so the harness connection should match the original sensor. Inspect the connector and wiring for corrosion, heat damage, or loose terminals before replacing the sensor.

Quality Assurance

Walker Products focuses on precision engine-management components, and this sensor is engineered to provide the temperature signal required for accurate fuel calculation and emissions control on the listed Chevrolet and GMC applications.
