Walker 273-10271 Exhaust Gas Temperature (EGT) Sensor

Walker 273-10271 Exhaust Gas Temperature Sensor

Walker Products 273-10271 is an exhaust gas temperature (EGT) sensor built for exhaust-mounted temperature monitoring in select Volkswagen applications. It is a direct-fit style sensor with a 14.0 mm thread diameter, 360.0 wiring harness length, black connector, and a 2-wire blade-terminal design.

Compatible with 2011-2012 Volkswagen Touareg T4 applications noted as EGT sensor before the DOC, this sensor supports accurate exhaust temperature feedback for the engine management system. Walker Products 273-10271 is also referenced by part number ETS10271 for cross-checking during replacement.

Product Details

Walker Products has supplied automotive fuel system and engine sensor components since 1946, with manufacturing and engineering support focused on meeting OEM standards and specifications. The Walker Products line includes engine management components such as oxygen sensors, throttle position sensors, cam and crankshaft sensors, fuel injectors, and related electrical parts. This EGT sensor is part of that broader product line and is intended for vehicles that require exhaust temperature measurement before the diesel oxidation catalyst.

For fitment verification, this sensor is listed for 2011-2012 Volkswagen Touareg models in the T4 configuration. Use the vehicle notes and connector details to confirm the replacement matches the original sensor before installation. Part number 273-10271 is the primary reference, and ETS10271 is a listed interchange number for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings reported to the engine control system
• Diesel aftertreatment monitoring issues tied to the sensor before the DOC
• Connector or harness mismatch during EGT sensor replacement
• Driveability concerns caused by inaccurate exhaust temperature input

Installation Notes and Tips

Confirm the original sensor location before replacement, since this application is noted as before the DOC. Match the 14.0 mm thread diameter, 2-wire blade terminal layout, connector shape, and harness length to the removed part. Inspect the exhaust bung threads and connector condition before installation, and verify all wiring is routed away from heat and moving components.

Quality Assurance

Walker Products manufactures engine sensor and fuel system components to meet or exceed OEM standards and specifications. The company is ISO 9001 and IATF 16949 certified, with product management and engineering support used to maintain application accuracy and technical documentation.
