For Toyota, It had been a very difficult few weeks. The company recalled millions of car for a humid accelerator pedal at first, then finally they searched for a remedy and it was announced by the world’s largest automaker that they would stop producing affected vehicles. Toyota has its fix now. And the details are: the fix is essentially a shim. When it is installed between the firewall and the pedal assembly, the shim alters the relative location of two halves of a friction device.
The device deliberately moves with some resistance in such a way that this drive-by-wire strangle mechanism gives the driver with some feedback through the throttle pedal. Slowing the pedal’s return rate, in rare cases humidity and condensation can cause too much friction. And this is what causes a “sticky” throttle or a “humid” throttle. Parts are already being shipped to dealers and training programs to install the bar are underway.
