It will be on either side of the catalytic converter.2. Unplug the electrical connector from the oxygen sensor by pushing the push tab upward and pulling downward until the connector is free from the sensor.
Due to their positioning, the bolts holding the sensors in levy are exposed to the elements. This exposure causes rust, which can bring about it perfect burdensome to loosen and remove the bolts.
Instructions
1. Place the O2 sensor under the motorcar by adjacent the exhaust tube to the catalytic converter. The oxygen sensor is a small part with electrical wires attached.Rust can adjust removing an O2 sensor hard.The oxygen sensor of an vehivle is a pivotal Element of the emissions manner. Its service is to observer and adjust the flow of air into the engine. The O2 sensors are located under the motorcar on the hottest stuff of the exhaust.
3. Apply a liberal amount of penetrating oil to the rusted nut that holds the oxygen sensor in place. Leave the oil on per the manufacturer's recommended time specifications before proceeding. Purchase a penetrating oil at your local auto parts store.
4. Attach the proper size wrench to the oxygen sensor's nut and turn to loosen it. If the nut will not loosen, re-apply the oil to the rusted nut and allow it to sit a longer period of time. Continue this process until the nut breaks loose.
