Introduction |
| One common wear item in modern cars is the oxygen sensor or O2 sensor. When they go bad, it can lead to rough idle and if ignored will leave motorists stranded. It is very easily diagnosed by a trouble code or check engine light. Many auto parts store will scan cars for free, and the code that it gives will indicate if there is a bad O2 sensor as well as many other possible issues. | | This fix will involve finding the sensor, unplugingunplugging it, unthreading it, and reinstalling a new sensor in its place.
***Reminder:*** Engine bays are usually very dirty so a pair of work gloves or even non latex style medical gloves can make clean up easier. Thinner gloves are better for dexterity since there is a small plug to manipulate. |
