Walker 211-2046 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Porsche

Walker 211-2046 is a sensor-only engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. With a 2-terminal blade connection, oblong female connector, and direct-fit design, it supports accurate engine management on Porsche applications including 718 Cayman, 718 Boxster, 718 Spyder, 911, Cayenne, Macan, and Panamera.

Walker Sensor Only parts are focused on the sensor itself, making them a practical choice when the original connector and harness are not being replaced. Part number 211-2046 is engineered for OE-style resistance values, thermal response, and signal output to help maintain factory system communication.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Sensor-only design with no wiring harness included
• Blade terminal type with 2 terminals
• Oblong female connector shape for factory-style fitment
• Built with heat-resistant materials for coolant and vibration exposure
• Direct-fit replacement for select Porsche cooling system applications
• Walker 211-2046 cross-references Standard Ignition TX180 for the same application

Detailed Description

Walker Products 211-2046 measures coolant temperature so the engine control module can adjust fuel delivery, ignition timing, cold start enrichment, and cooling fan operation. That data is critical on Porsche models where precise thermal control affects drivability, emissions, and fuel economy. This sensor is designed to match OE specifications for signal behavior and thermal response, helping the ECM read temperature accurately across normal and high-heat operating conditions.

Compatible With 2017-2025 Porsche 718 Cayman, sensor only; 2017-2023 Porsche 718 Boxster, sensor only; 2020-2023 Porsche 718 Spyder, sensor only; 2017-2019 Porsche 911, location-engine coolant hose; sensor only; 2011-2018 Porsche Cayenne, location-engine cylinder head; sensor only; 2015-2018 Porsche Macan, location-engine cylinder head; sensor only; 2010-2016 Porsche Panamera, location-engine cylinder head; sensor only; and 2014 Porsche 911, sensor only. The part number 211-2046 is a direct-fit solution for technicians replacing a failed coolant temp sensor or diagnosing a check engine light tied to temperature input.

Common Issues It Can Help Solve

• Incorrect coolant temperature readings at the ECM
• Check engine light related to coolant temperature sensor faults
• Hard cold starts or overly rich cold-start operation
• Cooling fan behavior that does not match engine temperature
• Fuel economy or drivability issues caused by inaccurate temperature input

Installation Notes and Tips

Verify the connector style, terminal count, and sensor location before installation. This part uses a female oblong connector with blade terminals and does not include a wiring harness. On Porsche applications such as the 718 Cayman, 718 Boxster, 718 Spyder, 911, Cayenne, Macan, and Panamera, confirm the original sensor position and compare the old unit to the replacement before final installation.

Quality Assurance

Walker Products designs this coolant temperature sensor to OE specifications for resistance values, thermal response, and signal output. The sensor is built from durable, heat-resistant materials to withstand coolant exposure, vibration, and repeated temperature swings in factory cooling systems.
