Interesting that this old thread pops up today. I just ordered a "vehicle speed sensor" today from Napa online for $100. I have the same symptoms that Nigel had. I checked the Lexus service manuals and counted the number of blinks that the OD (overdrive) light gives as a code. My code is 42 stating that the primary speed sensor is bad. I will keep everyone posted of if this works or not. One additional observation is that when the speedometer indicates "0 mph" the odometer is not working. So, I don't know exactly how many miles are on my ES300, which shows 150,000 miles.
