Service throttle sensor??

I was driving in about a solid 2-3 miles of stop and go traffic,varying between 0-5 MPH just barely tapping the throttle to keep up with very slowly moving traffic... 70 degrees every thing normal....
All of a sudden the FCW/ACC flashes need service appx 2-3 seconds then the "service throttle sensor" flashes for about 3-5 seconds. Scary but the error clears itself and we continue on...
About 90 sec later the "service throttle sensor" lights up again, and this time the dial mileage indicator goes to 99 MPG and the fuel pedal goes dead... Vehicle does not die but will not respond to any throttle request....
Had to roll of the side of the road to stop. NO codes or messages store in the EVIC.
Shut off and restarted the vehicle and it ran fine ever since. Still no codes stored in EVIC.

Any ideas what would cause this? Does repeatedly tapping on the throttle freak the sensor out? Is this worth mentioning to the dealer? Any one else have this ever happened to them? If so any resolve ?

Would freak my wife out if it happened to her..she was with me, but if she starts to think the vehicle is unreliable, she just won't drive it..... This is the only real prob I have had since owning.. 14k miles.....

Re: Service throttle sensor??

Are you a left foot braker? Seen one or 2 other threads a while ago and the cause was braking with the left foot, essentially momentary application of gas and brake without realizing it triggers conflicting data and safety feature kicks in... Think the whole Prius thing and preventing unintended acceleration,

Re: Service throttle sensor??

Well I am not normally a left foot braker, but i wouldn't rule it out in that situation..it is one possibility!
Is this a recordable error or just something the vehicle may be prone to in that limited situation only?
Other than that it has been flawless ! 😄

Its always good to start with the simple things - if it still happens and you know you weren't near the brake with your left or right foot then its probably worth a visit to the dealer.
