Walker 211-2066 Air Charge Temperature Sensor

Walker Air Charge Temperature Sensor for Ram

The Walker Products Air Charge Temperature Sensor monitors incoming air temperature through resistance changes and sends that data to the engine computer for fuel calculation. For 1997 Dodge Ram 2500 and 1997-1998 Dodge Ram 3500 applications, this sensor supports accurate air-fuel control, cold-start performance, and emissions management.

Walker Sensor Only line parts focus on the sensing element itself for direct replacement needs. Part number 211-2066 is built for drivers servicing engine management faults on Dodge Ram 2500 and Ram 3500 trucks where precise intake air temperature input is required.

Key Features

• Air charge temperature sensor for engine management systems
• Measures intake air temperature through resistance-based signal output
• 1 female connector with oblong shape
• 2 male terminals with pin-style terminal type
• Walker Sensor Only product line
• Part number 211-2066 for targeted replacement searches

Detailed Description

Walker 211-2066 is an air charge temperature sensor used by the engine computer to determine how much fuel to deliver based on incoming air temperature. That input affects drivability, fuel control, cold-start behavior, and emissions performance. This sensor is a direct-fit service part for 1997 Dodge Ram 2500 and 1997-1998 Dodge Ram 3500 models listed in the fitment data.

As part of Walker’s Sensor Only line, this component is focused on the sensing function needed for engine diagnostics and repair. If you are searching for a Walker air charge temperature sensor for a Dodge Ram 2500 or Ram 3500, part number 211-2066 is the reference to use.

What It Helps Address

• Incorrect air temperature readings sent to the engine computer
• Hard cold starts and unstable warm-up behavior
• Poor fuel delivery control caused by faulty sensor input
• Reduced engine efficiency from inaccurate intake air data
• Emissions-related drivability concerns tied to sensor failure

Installation Notes and Tips

Verify the connector style, terminal count, and sensor location before installation. This part uses a female connector, oblong connector shape, and pin terminals, so matching the existing harness is important. Confirm the vehicle application against the listed fitment for 1997 Dodge Ram 2500 and 1997-1998 Dodge Ram 3500 before replacement.

Quality Assurance

Walker is a recognized name in engine management components, and this sensor is engineered to provide the signal accuracy needed for proper fuel calculation and emissions control. Part number 211-2066 is listed for the specific Ram applications shown above.
