So do you know if the pedal itself went to the floor, or was it possibly just the thottle itself going wide open?
The pedal itself went to the floor.
What's really weird about that is the pedal on these (04 and up) are Throttle by Wire. It's weird how it "pulled" the pedal to the floor.
Could the cruise control be a culprit here? In previous cars I've had I noticed the pedal does move a little as the terrain changed... Could the cruise control module have gone nuts!!!SENT FROM MY EVO 4G
Cruise control moves the pedal in vehicles with a cable-driven throttle, since that is a mechanical connection between throttle and pedal, but not in drive-by-wire vehicles. In drive by wire vehicles there is a pedal position sensor which sends data to the engine computer, which in turn sends a signal to the electronic throttle actuator controller. There is no feedback to position the pedal to correlate with the throttle.
Touche! Your kung fu is better then mine! Lol well then that can almost rule out the cruise control.... I'm kinda stumped on this one... How dose a mechanism that only sends a signal. But will not recieve one. React as if it was recieving a signal to make the pedal go down? Short it the system maybe? SENT FROM MY EVO 4G
That, my boy. Is the answer we're waiting on from the OP. Guess we need to see what his dealer says.Sent by my Atrix 4G
