Twenty-three minutes; about as absurd as you can get. > OR, he wasn't confused at all -- except for the confusion that comes from wearing the brakes down to the backing plates and not stopping. This isn't really about how to stop a car from doing wht it has decided to do, it's more about cars making decisions that they ought not be making. The part that matters is that the drivers of these cars can't slow down by simply taking their foot off of the gas, then can't slow down by applying the brake which is an activity that reasonably ought to stop the car not merely slow it down. Nobody should have to push the gear selector to N for any reason.

Only the NHW11 (2001-2003) and maybe NHW10 (97-00) used dual "rheostats" (potentiometers) The NHW20 (2004-2009) and ZVW30 (2010-...) along with all other Toyota's with electronic throttles (Denso and CTS) use a twin hall effect sensor. |
