Walker 211-2056 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Porsche

Walker Products 211-2056 is a sensor-only engine coolant temperature sensor that sends real-time coolant temperature data to the ECM. For Porsche 911, Cayenne, Carrera GT, and Boxster applications, accurate temperature input supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation.

Sensor Line Details

Walker Sensor Only parts are built to match OE resistance values, thermal response, and signal output for factory-style communication with the vehicle control system. Part number 211-2056 uses a blade terminal type, a circle-shaped female connector, and 2 terminals, with no wiring harness included.

• Engine coolant temperature sensor for Porsche cooling system monitoring
• OE-style resistance values and signal output
• Heat-resistant construction for constant coolant exposure and temperature swings
• Direct-fit sensor-only design for factory-style replacement
• Blade terminal type with circle connector shape
• Female connector, 2-terminal configuration

Detailed Description

Walker 211-2056 is an engine coolant temperature sensor engineered to provide the ECM with accurate coolant temperature readings. That data is used to manage fuel injection, ignition timing, cold-start enrichment, and radiator fan operation. This makes the sensor an important part of drivability and emissions control on Porsche 911, Porsche Cayenne, Porsche Carrera GT, and Porsche Boxster applications. This part cross-references Standard Ignition TX142 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to coolant temperature signal faults
• Hard starting or rough running during cold starts
• Incorrect fuel mixture caused by inaccurate temperature input
• Cooling fan operation problems tied to sensor data
• Poor fuel economy or elevated emissions from faulty temperature readings
