The “amateur electrical work”, a pound to a penny will be the grafting on of the old connector on to a general purpose sensor.
I did some work quite recently where I amassed sensors from several types & makes of car, the characteristics are so close as to make you ask why such a price disparity.
I didn’t assess the dynamic characteristics of each by screwing them into the car, in turn & run it. Those tested gave similar results.
At the end of the day you’re looking for an MOT pass, the test is academic.
