Bosch 17148 oxygen sensor for the 2009-2014 Volkswagen Jetta 4-cylinder 2.0L and other vehicles reads the air-fuel ratio in the exhaust and passes it to the engine computer. This upstream sensor gives the ECU continuous readings it uses to adjust fuel delivery.

The listing covers a wide range of Volkswagen, Audi and Porsche models. It is also a Passat oxygen sensor for the 2012-2014 Volkswagen Passat 4-cylinder 2.0L.
