This part cross-references Standard Ignition ETS79 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings in the engine management system
• Emission control monitoring issues tied to the EGT circuit
• Connector or harness mismatch during sensor replacement
• Service needs on Audi Q7 and Volkswagen Touareg exhaust sensor locations

Installation Notes and Tips

Verify the connector shape, terminal type, thread diameter, and harness length before installation. Confirm the vehicle application by year, make, model, and exhaust position: Fits 2009-2012 Audi Q7, T4 - EGT Sensor Before DOC; Walker Products. Fits 2009-2010 Volkswagen Touareg, Exhaust Gas Temperature Sensor for T5 After DOC applications; Walker Products. Inspect the exhaust mounting point and wiring routing before final installation to ensure the sensor seats correctly and the harness reaches the factory connection point.
