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.
An O2 sensor error code does not necessarily mean the O2 sensor is bad and in fact they usually aren't bad. You need to hook a scanner to your OBD-II computer interface connector under the steering wheel and see why your engine's air/fuel mixture is not being controlled properly by the ECM computer.
