We don't even know what kinda of issues the FRS/BRZ is going to have. |

No surprise that an American org would drop issues with ford as they try to grow, same people that had a problem with fools using the wrong pedal in Toyotas.

Actually, Toyota accelerator pedal position sensors HAVE been found to be susceptible to failures due to tin whiskering (extremely fine filaments that can grow to millimeters in length and cause intermittent short-circuits).
http://nepp.nasa.gov/WHISKER/referen...app-sensor.pdf Hmm, a mechanical throttle cable doesn't seem like such a bad idea after all... |
Mechanical throttle cable doesn't allow flexibility in VVT control :P
Reading that article, maybe they could've insulated the contacts (at slightly higher cost)... |

The issue described in that document wasn't responsible for the so-called sudden acceleration syndrome. Pedals stuck to the improperly mounted floor mat was, and also people pressing the wrong pedal. Yes, it was clearly a witch hunt and I'm not surprised that, after trying so hard (and only for Toyotas) they found something. I assume you haven't heard about stuck mechanical throttle cables; I did. |
The issue described in the document did describe a failure that resulted in "unintended acceleration".
It has been totally PROVEN that Toyota throttle pedal angle sensors have developed whiskers that have been shown to cause potentially dangerous malfunctions. In the case cited, the failure was *relatively* benign, but still dangerous. It is totally possible that if other leads in this sensor were shorted that you could get less benign/more dangerous types of failures. THERE IS AND HAS BEEN MORE GOING ON WITH TOYOTA THROTTLES THAN FLOORMATS OR WRONG PEDAL APPLICATION. |

What would be better would be for Europe to revisit RoHS requirements and to allow 3% lead plating of leads and solder in electronics, with appropriate environmental controls in place at production and end of life. Problem is, many electronics companies have invested heavily in going to zero-lead. Medical and space applications have waivers to use lead in electronics, IMO automotive and many other applications should, too. |
