Bronchitis is a respiratory disease in which the mucus membrane in the lungs' bronchial passages becomes inflamed. As the irritated membrane swells and grows thicker, it narrows or shuts off the tiny airways in the lungs, resulting in coughing spells that may be accompanied by phlegm and breathlessness.
This will help you easily replace the sensor next time. Thread the new sensor in place finger tight, then tighten the sensor with the socket and ratchet. Plug in the oxygen sensor electrical connector and lower your Accord with the floor jack, if you had to raise it. Reconnect the ground (black) battery cable with the wrench.
One of the key sensors in this system is the oxygen sensor. It's often referred to as the O2 sensor because O2 is the chemical formula for oxygen (oxygen atoms always travel in pairs, never alone). The first O2 sensor was introduced in 1976 on a Volvo 240. California vehicles got them next in 1980 when California's emission rules required lower emissions.
