It reminds me of the Dateline scandal over GM pickup gas tanks.

Anything to get your viewers to praise you for "looking out for their concerns"

The drawing they depicted does not make any sense...

VCP1 = 5V Reference for APP 1.
VCP2 = 5V Reference for APP 2.
VPA1 = Signal Circuit for APP 1.
VPA2 = Signal Circuit for APP 2.
EP1 = Low Reference for APP 1.
EP2 = Low Reference for APP 2.

So basically they are shorting the 5V reference for APP1 to the signal circuit of APP 2. If this happens a high voltage DTC will set for the APP2 and the pedal will default to 0%. Then, the APP1 signal voltage will be raised because they are shorting the APP 2 signal (which is shorted to 5V) through a resistor. This may increase in the pedal angle of sensor 1, but since sensor 2 is outside of the normal sensor voltage range, the pedal default should be 0.

So unless Toyota trusts sensor 1 even if sensor 2 is shorted to 5V (which I've never seen and highly doubt), what this guy is touting is pure bullshit.
