Walker 211-2035 Engine Coolant Temperature Sensor - Engine Block or Front

Engine Coolant Temperature Sensor Overview

Walker 211-2035 is an engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. That signal is used for fuel injection, ignition timing, cold start enrichment, and cooling fan operation, making accurate temperature feedback important for drivability and emissions control. This Sensor Only line is a direct-fit replacement for select Audi, Porsche, and Volkswagen applications.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Matches OE resistance values, thermal response, and signal output
• Durable, heat-resistant construction for coolant and vibration exposure
• Direct-fit design for straightforward replacement
• Female connector with oblong shape, 2-pin terminal layout, and pin terminals
• No wiring harness included

Product Details

Walker Products Sensor Only part number 211-2035 is engineered for factory-style integration in cooling system temperature monitoring. By reporting coolant temperature accurately, the sensor helps the ECM manage engine operation across cold starts, normal driving, and high-temperature conditions. This part cross-references Standard Ignition TX275 for the same application. Common search terms for this part include Audi A4 coolant temperature sensor replacement, Porsche Cayenne engine coolant temperature sensor, and Volkswagen GTI coolant temp sensor 211-2035.

What It Helps Address

• Check engine light related to coolant temperature signal faults
• Hard starting or rough running during cold starts
• Incorrect fuel delivery or ignition timing caused by bad temperature input
• Cooling fan operation issues tied to inaccurate coolant readings
• Poor fuel economy or elevated emissions from incorrect ECM temperature data

Installation Notes

Verify connector style, terminal count, and sensor location before installation. This part uses a female oblong connector with two pin terminals and does not include a wiring harness. Confirm the application location on the engine block, cylinder head, or coolant hose as listed for your vehicle. Compatible With select Audi RS5, Audi Q5, Porsche 911, Porsche Macan, and Volkswagen Jetta applications; always match the exact year, engine, and sensor location before replacement.

Quality Assurance

Walker Products builds this sensor to OE-style specifications for resistance, thermal response, and output signal consistency. The heat-resistant design is made for continuous exposure to coolant, vibration, and temperature swings found in modern engine cooling systems.
