 I wonder if it has to do with the speed that it changes or that it doesn't change. The other question I've got is, can we check this with a voltmeter? So I'm not trusting a scan tool or a computer. Can I see what actual voltage is? I can back-probe it. Can we back-probe it and just verify, does a meter match what the scanner is seeing, what the computer is saying? Because what if somebody is lying to us?
