Walker 211-2094 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Volvo

Walker 211-2094 is a direct-fit engine coolant temperature sensor for select Volvo applications. It provides the ECM with real-time coolant temperature data so the engine can manage fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation.

Built as part of Walker’s Sensor Only line, this replacement sensor is engineered for factory-style signal output and resistance values. It is a practical choice for Volvo S80 and Volvo XC90 repairs where accurate coolant temperature input is needed for drivability and emissions control.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Direct-fit design for straightforward replacement
• Engineered to OE-style resistance values and thermal response
• Heat-resistant construction for coolant system environments
• Blade terminal type with square connector shape
• 2-terminal female connector; wiring harness not included
• Walker 211-2094 replacement sensor for factory-style integration

Product Line Details

Walker’s Sensor Only line focuses on replacement sensors built to match the electrical behavior and connector style expected by factory systems. For this application, Walker 211-2094 is designed to deliver stable coolant temperature readings so the ECM can respond correctly during warm-up, normal driving, and fan control events.

Detailed Description

This engine coolant temperature sensor is used to report coolant temperature to the vehicle computer, which then adjusts fuel injection, ignition timing, cold-start enrichment, and radiator fan operation. Accurate temperature feedback is important for maintaining smooth operation, fuel economy, and emissions performance. Walker 211-2094 is built for select 2002-2005 Volvo S80 and 2003-2005 Volvo XC90 models, making it a direct replacement for common coolant temperature sensor service needs.

This part cross-references Standard Ignition TX134 for the same application.

Common Issues It May Resolve

• Check engine light related to coolant temperature sensor performance
• Hard starting or rough cold-start operation
• Incorrect fuel mixture caused by inaccurate temperature input
• Cooling fan behavior that does not match engine temperature
• Poor fuel economy or drivability concerns tied to sensor signal errors

Installation Notes and Tips

Fits 2002-2005 Volvo S80, sensor only. Fits 2003-2005 Volvo XC90, sensor only. Confirm the connector shape, blade terminal layout, and 2-terminal female configuration before installation. Inspect the cooling system connector and surrounding wiring for corrosion or heat damage, and verify the replacement sensor matches the original mounting style and electrical connection.

Quality Assurance

Walker Products engineers this sensor to align with OE specifications for resistance values, thermal response, and signal output. The heat-resistant construction is intended for the demanding conditions found in coolant system service, including vibration and repeated temperature changes.
