Research on Oxygen Sensor for Subaru Legacy

The oxygen sensor is one of the overlooked parts and most automobile owners do not know the symptoms of bad oxygen sensors. Contamination with oil, coolant or silicon will make the oxygen sensors to fail. A failed oxygen sensor can cause the vehicle to fail emission tests and cause a trouble code to be set and illumination of the check engine light. It is important to know the source of fluid in case of oxygen sensor failure that is caused by fluid contamination. Sometimes, exhaust leaks that trigger an oxygen sensor trouble code can be confused for oxygen sensors fail. In such cases repairing the leak solves the problem.

To maintain the good performance of your automobile, it is important to ensure that the oxygen sensor is in a good state. The oxygen sensor's duty in the engine is to perform tests on the car's exhaust and determine the level of oxygen within the exhaust and relays the message to the vehicle's computer. A bad oxygen sensor leads to negative environmental effects as the levels of air pollution are greatly increased.

How do you replace oxygen sensors?

Start by lifting the front end of the car using either ramps or a jack. Slide under the car and locate the black plastic box that houses the oxygen sensors lead harness connectors. Remove the two plastic nuts that secure the box to the underside of the car and separate the appropriate harness connector by pulling up slightly on the retaining tab with a screw driver. Remove the protective heat shield from around the sensor and remove the appropriate sensor leads from the retaining clips on the underside of the car. Remove the old sensors by loosening the threads on it. Locate the oxygen sensor on the catalytic converter by loosening the threads through spraying the PB Blaster or other penetrating lubricant into the crack between the sensor and the bung. Do not spray too much lubricant that can drip into the catalytic converter. The old oxygen sensor can now be removed and replaced with a new one.

When I first started looking for O2 Catalytic Converter Sensors, I was shocked as the prices; however, Part Geek clearly described the Upstream and Downstream sensors needed and they were very reasonably priced... and they shipped VERY quickly.

1998 Subaru Legacy Oxygen Sensor

Reviewer: Magnum Parker

Exact fit is important when ordering online and this was perfect. Just like OE it has quality wire cover to protect from heat. Harnest is just slightly longer then OE but not a problem at all and great price.
