On the subject of sudden acceleration NHTSA could not find a design flaw that would have led to a short that caused sudden acceleration. Due to absent of evidence it had to conclude that it was driver error. However it left the door open if new evidence could show where the short came from. Also NHTSA did not declare that a short could not cause the sudden acceleration as Dr. Belt theorized. They just could not find a design problem that caused this short.

In Dr Belts paper, specifically mentioned by the NHTSA, he states the following:

The amplitudes of the two sensors are then compared and, if they differ by more than a specified tolerance, the vehicle drive power is disabled and a diagnostic trouble code (DTC) is set. If the amplitudes of the two sensors agree, then the common amplitude is used by the inverter’s control system to adjust the torque of the drive motor

The analog output from one of the APP sensors is also converted into a fast rise-time digital signal and inserted into a digital CPU input, where it punches a time clock that provides the time of the transition.

Only one of the sensor data is logged so there is no way to compare to see if there is any anomalies. However both APP sensors share a common +5v and GND so both sensors would experience identical surges in the event of voltage leakages or induction.

The rise in the APP sensor GND voltage may be explained by an increase in the APP sensor GND current acting on the parasitic resistance in the APP sensor GND line. But the cause of the increase in the APP sensor GND current must still be found.

A rise in the APP sensor GND voltage maybe explained by increase in current.

The valleys, on the other hand, might be explained by the +5V APP sensor voltage regulator going into reset

Like what is described in my previous post, EMP can induce currents that can cause rebooting or reset. Based on what Dr. Belt describes it appears this is precisely whats happening. A current is being induced in the wiring causing a signal from the APP sensor and the +5 voltage regulator then attempts to reset as described below:

At this point, the leakage current will suddenly increase to an even higher value that is not limited by the device itself. This will cause the external +5V regulator to go into reset.

Dr Belt believes the current is leakage but my hypothesis is its being induced by EM radiation causing the current to increase and the +5v regulator to reset as was seen in the Tesla Dr. Belt examined.

If the current is being induced there would have to be example of localized EMPs.

The location of the projections of these regions onto the Earth depends on the solar wind dynamic pressure and magnetic field. The occurrence of various waves also depends on conditions in the solar wind and in the magnetosphere. Changes in orientation of the interplanetary magnetic field or an increase in solar wind velocity can have dramatic effects on the type of waves seen at a particular location on the Earth.

From the EMP commission report:

relatively low electromagnetic stress levels, a portion of a DCS process controller provided false indications of the process status. An operator interface indicated a switch was on when in actuality it had been turned off, while internal voltage and temperature were reported as out of their normal operating ranges when they were actually normal… In addition to false readings from the sensors, direct malfunctions of some tested control elements were also noted

Sounds alot like what happened with tesla sensors. Sensors giving off false readings due to relatively low electromagnetic stress. In other words EM induction causes currents to flow giving off false readings. Since Teslas APP sensors are connected to same wiring induced currents would cause both sensors to register as user pressed on accelerator.


Is there any evidence these pulses are a threat?

EMP is the perfect sneak attack. The invisible, silent radio pulse is only apparent when electronics stops working.[t][/t] At present there is no way of telling when an EMP attack has occurred, or what it has affected, so the Pentagon’s Defense Threat Reduction Agency is working on sensors to detect and analyze EMP sensors under its Conventional Nuclear

So the Pentagon sees EMPs as such a threat that its developing sensors to detect more localized EMPs (like sensors worn by soldiers). You could argue that is is only because of an increased EMP threat from foreign contries on smaller scales (like EMP gun). However the sensors could just as easily detect earths magnetic field pulsations that cause localized electronic glitches.
