We see more and more of it in the car industry, fretting. Volvo's especially.
The size of male/female terminals throughout the cars have shrunk in size to maybe only a 10th or less of 20-30 years ago but still delivering about the same amount power or many times a low voltage signal.
The surface area of the whole connector is so much less that it does not take much of corrosion, galvanic or traditional to drop the signals. The clamping force of the female terminal is also a lot less compared to the traditional old spade connectors where the metal more or less dug into each other when pushed together.
This J16 oxygen sensor splice is more of a galvanic corrosion type where it is nothing wrong with the splice itself but it has built up a tiny layer of patina to mess with the low current signal.
Volvo had big problems with the positive battery cable terminal between 98-2004 where at a 90° bent right at battery, the copper strands lost contact with the terminal. Absolutely nothing wrong with the crimp job since you could see the imprints of copper strands in the terminal metal when cut open but it developed so much resistance that the 90° bend got burning hot. Very easy to detect since if you burned your fingers touching the terminal, it was bad.
Similar problems is with the 9-5 battery cable at alternator lug ring. Perfect crimp but just too much power passing through and maybe dissimilar metals creating a patina over time.
