Bosch Oxygen Sensor P/N:16643
Bosch 17287 oxygen sensor for the 2005-2012 Nissan Frontier 4-cylinder 2.5L and other vehicles measures the air-fuel ratio in the exhaust for the ECU. As an upstream wideband sensor, it gives the ECU more detailed readings than a switching sensor.
A check engine light, poor fuel economy or a rough idle can mean a sensor is slow or failing. Before you replace it, rule out damaged wiring or an exhaust leak near the sensor, since other faults can trigger the same light.
It is an oxygen sensor for the 2005-2012 Nissan Frontier 4-cylinder 2.5L and the 2009 Suzuki Equator 4-cylinder 2.5L. This listing is one upstream sensor; the 2.5L engine takes just one in that position.
