Testing suspension height sensors
I removed the LR, again, and tested it a second time, same result.
Putting 4.1V into it, I get 3.56V out of the center pin. Thing is, it's 3.56V, period, no change, no matter how the potentiometer is oriented.
Now, if I measure resistance across the positive and negative leads, it's variable based on position.
Before I head down the parts path, I pulled the LF, because why not, I have four of them.
Same exact result, but this time 3.62V, with no change upon moving the arm connected to the potentiometer.
The insulation-piercing multimeter leads I got are lame, so I got better ones, will be here, tomorrow, and I'll attempt testing on the car, again. Looking at the Techstream, they all change values as the car changes its height, but the two rear ones have readings which, while variable, don't make sense compared to the front two, or general logic, for that matter.
Anyone ever seen this kind of behavior? I'm certain I wired it up properly, as I did it in front of the computer's monitor, so I had a reference in front of me.
