Walker 210-1159 Air Charge Temperature Sensor

Walker Air Charge Temperature Sensor 210-1159

Walker Products Air Charge Temperature Sensor 210-1159 measures incoming air temperature through resistance changes so the engine computer can calculate fuel delivery with greater accuracy. It is a Sensor Only replacement for select Ford and Lincoln applications, including Explorer, Flex, Taurus, MKT, and MKS.

Sensor Only Design

Walker Sensor Only parts focus on the sensing element needed for engine management diagnostics and repair. This air charge temperature sensor supports precise air temperature input for improved fuel control, cold-start operation, emissions management, and overall drivability on vehicles such as the Ford Explorer and Ford Taurus.

Detailed Description

Walker 210-1159 is an air charge temperature sensor that reports intake air temperature to the vehicle’s onboard computer. By translating temperature changes into an electrical signal, it helps the engine control system determine the correct fuel delivery strategy. That makes it a direct-fit service part for diagnosing temperature-related drivability concerns on 2013-2019 Ford Explorer, 2010-2019 Ford Flex, 2010-2019 Ford Taurus, 2010-2019 Lincoln MKT, and 2010-2016 Lincoln MKS.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Symptoms

• Incorrect air temperature readings in engine data
• Hard cold starts or rough cold-start operation
• Poor fuel economy caused by inaccurate fuel calculation
• Reduced engine response from faulty temperature input
• Emissions or drivability issues tied to sensor signal errors

Installation Notes

Verify connector style, terminal count, and sensor location before installation. This unit uses a female oblong connector with two male spade terminals, so matching the electrical connection is important for proper fitment. Confirm the vehicle application against the listed Ford and Lincoln models before replacing the original sensor.

Quality Assurance

Walker Products is known for engine management components built around accurate signal delivery and OE-style service replacement standards. This part number 210-1159 is intended for direct replacement use on the listed applications.
