Plymouth Repair: Plymouth Voyager Oxygen Sensor Repair, plymouth voyager, oxygen sensor

Question
I own a Plymouth Voyager Van, 103 thous. plus miles, 6 cyl.  The "check engine" light came on now twice, but does not always come on each time I drive it.  A mechanic said it was the "Oxygen Sensor."  Question:  Is this a repair we can make ourselves, and do you offer instructions to do so?  Thanks in advance.  bbohannon7@aol.com
