Walker 273-10143 Exhaust Gas Temperature (EGT) Sensor

Walker 273-10143 Exhaust Gas Temperature Sensor

Walker Products 273-10143 is an exhaust gas temperature (EGT) sensor for diesel emission control systems that monitor exhaust heat before the diesel particulate filter. It uses a 2-wire design with a brown connector, D-shaped female connector, and 14.0 mm thread diameter for direct replacement service on select Volkswagen and Audi applications.

Walker Products has supplied engine management and fuel system components since 1946, with manufacturing and engineering support focused on OE-level specifications. The Walker Products line includes sensors and other engine management parts built for accurate vehicle application matching and technical support.

Installation Notes and Tips

Confirm connector shape, terminal type, thread diameter, and mount location before installation. This sensor is positioned in the exhaust stream, so allow the system to cool fully before service and verify the application against the vehicle’s OE sensor location, especially on Volkswagen models with a sensor before the diesel particulate filter.
