English term or phrase: zero vault plane
But generally all of our analog voltage inputs in particular things such as our manifold absolute pressure sensors, our throttle position sensors, our thermistor inputs such as intake air temperature and engine coolant temperature, rely on being able to very accurately measure voltages from the sensor zero vault plane, so it's important that those sensors are grounded at the sensor zero volt input on the ECU.

Generally we want this to be somewhere around about a third of the amplitude, just as a good starting point or rule of thumb. We're also going to end up with a little bit of background noise that's generally occurring around about that zero volt plane as well. So the good thing about this is that you can see the arming threshold is well above that background noise level so it allows the ECU to really clearly detect the actual signal. Now if we look at what happens if we now increase our RPM, let's say our first example there was recorded at 800 RPM at idle. Now if we look at what's going on at maybe 5000 RPM, we're going to see that the amplitude this time is much greater than our first example.
