Bosch Oxygen Sensor P/N:16809
Bosch 17305 oxygen sensor for the 2012-2013 Volkswagen Jetta 4-cylinder 2.0L and other vehicles measures the air-fuel ratio in the exhaust for the engine computer. This upstream wide-band sensor gives the ECU more detailed readings than a switching sensor.
A check-engine light or poor fuel economy can mean the sensor is no longer reporting the air-fuel ratio correctly. Before you replace it, rule out an exhaust leak near the sensor and damaged wiring or a loose connector, since either can skew the reading too. This listing is one sensor, and the 2.0L engine takes one upstream.
It is a direct-fit replacement for the 2012-2013 Volkswagen Jetta 4-cylinder 2.0L and the 2012-2013 Volkswagen Beetle 4-cylinder 2.0L.
