Walker 210-1149 Air Charge Temperature Sensor

Air Charge Temperature Sensor for Engine Management

The Walker 210-1149 Air Charge Temperature Sensor measures incoming air temperature through resistance changes so the engine computer can calculate fuel delivery with greater accuracy. This Sensor Only replacement is built for vehicles that rely on precise intake air temperature data for drivability, fuel control, and emissions performance.

Compatible With select Dodge Durango, Jeep Grand Cherokee, Jeep Wrangler, Ram 1500, and other Chrysler, Dodge, Jeep, and Ram applications listed below, Walker 210-1149 supports accurate engine management across a wide range of late-model platforms.

Key Features

• Air charge temperature sensor for engine management systems
• Sensor Only configuration for direct sensor replacement
• 1 female connector with 2 male blade-pin terminals
• Square connector shape for application-specific fitment
• Measures intake air temperature to support fuel calculation
• Walker part number 210-1149 for catalog and service reference

How It Works

The Walker Products air charge temperature sensor reports intake air temperature to the vehicle’s onboard computer. That input helps the engine control module adjust fuel delivery, improve cold-start behavior, protect the engine under changing temperature conditions, and maintain emissions compliance. The Sensor Only line focuses on the sensing element itself, making it a practical choice when the existing connector and related components are being retained.

What This Sensor Helps Address

• Incorrect air temperature readings sent to the engine computer
• Hard starting or rough cold-start operation
• Poor fuel delivery caused by inaccurate intake air data
• Reduced engine response tied to faulty sensor input
• Emissions issues related to improper air/fuel calculation
