Walker 211-1095 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Mercedes-Benz

Walker 211-1095 is an engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. For Mercedes-Benz SL600, S500, and other listed applications, accurate temperature input supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan control.

The Sensor Only line from Walker focuses on direct-fit replacement sensors engineered to match OE resistance values, thermal response, and signal output. Part number 211-1095 is designed for factory-style integration on Mercedes-Benz cooling system applications where precise temperature reporting matters.

Key Features

• Engine coolant temperature sensor for ECM temperature monitoring
• Direct-fit design for factory-style installation
• Engineered to match OE resistance values and signal output
• Heat-resistant construction for coolant and vibration exposure
• Blade pin terminal type with square connector shape
• 2-terminal, female connector with male terminals

Detailed Description

Walker Products 211-1095 is a replacement coolant temperature sensor for select Mercedes-Benz vehicles, including 1996-2002 Mercedes-Benz SL600, 1996-1999 Mercedes-Benz S500, and 1996-1997 Mercedes-Benz C280. It provides the ECM with the temperature data needed to manage engine operation, emissions control, and fan activation. The Sensor Only product line is focused on sensor replacement without unnecessary extras, making it a practical choice when diagnosing a temperature-related fault or replacing a failed sensor.

This part cross-references Standard Ignition TX209 for the same application.

What It Can Help Resolve

• Check engine light related to coolant temperature signal faults
• Incorrect fuel mixture during cold starts
• Delayed or unstable idle after startup
• Cooling fan operation issues tied to temperature input
• Poor fuel economy caused by inaccurate ECM temperature data

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This part uses a square connector with 2 terminals, so matching the electrical connection is important for proper fitment. Confirm the vehicle application against the listed Mercedes-Benz models and years, including SL600, S320, S420, S500, S600, CL500, CL600, SL500, C280, C36 AMG, E300, E420, SL320, and C220.

For best results, inspect the cooling system connector and wiring for corrosion or damage before installing the new sensor. Clear diagnostic trouble codes after replacement and confirm the ECM receives a stable temperature reading.

Quality Assurance

Walker engineers this sensor to OE specifications for resistance, thermal response, and output signal, with durable materials selected for continuous exposure to coolant, heat, and vibration.
