DENSO Auto Parts Oxygen Sensor P/N:234-4951
DENSO Auto Parts 234-4754 oxygen sensor for the 2011-2016 Audi A4 4-cylinder 2.0L and other vehicles reads exhaust oxygen for the engine computer. It is a heated, narrow-band sensor for the downstream position, left or right.
A check engine light with an oxygen sensor code or a change in fuel economy can mean a sensor has worn out, but other faults can set the same code. Before replacing it, look over the wiring and connector for melting, chafing or corrosion with the engine off and cool.
It is listed for a wide range of Audi, Volkswagen, Porsche and Bentley models, including the 2005-2012 Volkswagen Jetta 5-cylinder 2.5L and the 2006-2015 Jetta 4-cylinder 2.0L. It is also a Passat oxygen sensor for the 2006-2010 Volkswagen Passat 4-cylinder 2.0L and the 2008-2010 Passat V6 3.6L. If your car is not named here, look for it in the "Vehicles it fits" section. This listing is one sensor, and the 2011-2016 Audi A4 4-cylinder 2.0L takes one. It is built as an exact replacement and tested to OE standards.
