Walker 211-2169 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Audi

Walker 211-2169 is a sensor-only engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. For 1995-1996 Audi Cabriolet and 1996 Audi A4 / A4 Quattro applications, it supports accurate fuel delivery, ignition timing, cold-start enrichment, and cooling fan control.

Walker Products Sensor Only parts focus on the sensing element itself, making this line a direct replacement choice when the original connector and harness are being reused. Part number 211-2169 is engineered for OE-style resistance values, thermal response, and signal output.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Blade terminal type with square connector shape
• 4-terminal, female connector design
• Sensor only; wiring harness not included
• Heat-resistant construction for coolant and vibration exposure
• Direct-fit replacement for select Audi models

Detailed Product Information

This Walker engine coolant temperature sensor helps the ECM read coolant temperature accurately so the engine can adjust fueling, timing, and fan operation. On 1996 Audi A4, 1996 Audi A4 Quattro, and 1995-1996 Audi Cabriolet applications, the correct temperature signal is important for stable cold starts, consistent drivability, and emissions control. Part number 211-2169 is built to match factory-style electrical response for straightforward integration with OE systems.

This part cross-references Four Seasons 55146 and Wix 33785 for the same application.

What It Helps Address

• Check engine light related to coolant temperature signal faults
• Hard starting during cold engine operation
• Incorrect fuel mixture from inaccurate temperature input
• Cooling fan behavior caused by a faulty sensor reading
• Poor idle quality after warm-up

Installation Notes and Tips

Verify the connector style, terminal count, and sensor location before installation. This sensor uses a square female connector with four blade terminals and does not include a wiring harness. Confirm the cooling system is at a safe temperature before removal, and inspect the connector and surrounding wiring for corrosion or damage before installing Walker 211-2169.

Quality Assurance

Walker Products designs this Sensor Only coolant temperature sensor to OE specifications for resistance, thermal response, and signal output. The durable, heat-resistant construction is intended to withstand constant coolant exposure, vibration, and temperature swings in daily service.
