Walker 211-2120 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Porsche

Walker 211-2120 is an engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. For Porsche 911 and Porsche Macan applications, accurate temperature input supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan control.

Walker Products Sensor Only line focuses on direct replacement sensors that match OE-style electrical response and factory signal output. This Walker 211-2120 sensor uses a 2-pin female circle connector and a direct-fit design for straightforward replacement on the engine cylinder head or engine block, depending on application.

Key Features

• Engine coolant temperature sensor for ECM temperature reporting
• 2-pin terminal design with female circle connector
• Direct-fit replacement for factory-style installation
• Heat-resistant construction for coolant and vibration exposure
• OE-matched resistance values, thermal response, and signal output
• Compatible With 2021 Porsche 911, engine cylinder head location
• Compatible With 2019-2021 Porsche Macan, engine block location

Detailed Description

The Walker Sensor Only product line is built for technicians and repair shops that need a precise replacement sensor without unnecessary extras. Part number 211-2120 is engineered to provide stable coolant temperature feedback so the ECM can manage engine operation correctly. This matters on Porsche 911 and Porsche Macan models where accurate temperature data affects drivability, emissions control, and fan operation.

This part cross-references Facet 7.3356 for the same application. It also cross-references 1.830.356 and 530 356 for related replacement use.

Common Issues This Sensor Can Address

• Check engine light related to coolant temperature signal faults
• Incorrect cold-start fuel enrichment behavior
• Cooling fan operation that does not match engine temperature
• Poor fuel economy caused by inaccurate temperature input
• Ignition timing or drivability issues tied to faulty coolant data

Installation Notes and Tips

Verify the connector style, terminal count, and sensor location before installation. Walker 211-2120 uses a 2-pin female circle connector and does not include a wiring harness. Confirm whether the vehicle uses the engine cylinder head or engine block mounting location, then compare the old sensor to the replacement part before installation.

For Porsche 911 and Porsche Macan service work, inspect the connector for corrosion, coolant contamination, or damaged terminals before reconnecting. Clear diagnostic trouble codes after installation and confirm the ECM reads temperature correctly during warm-up.

Quality Assurance

Walker Products engineers this sensor to OE specifications for resistance, thermal response, and signal output so it integrates with factory systems as intended. Durable, heat-resistant materials help the sensor withstand continuous coolant exposure, vibration, and temperature cycling.
