it doesn't matter much in real life, but when I am parking my 2 rigs back to back I can
get so much closer with the 4runner than when driving the Yaris.

Agree....with a cable I can creep meticulously and with DBW sometimes I can and sometimes it bucks like a bull with a swollen prostate. I despise DBW but it's now the status quo.

we may see a recall for the YARIS . A driver of a 2006 PRIUS had her car take off and crashed into a stream . Claims wasn't the pedal or the mat . Not sure if YARIS ( 1.5 ltr. engine ) and PRIUS ( 1.5 ltr engine ) use same unit made by C.T.S. and both are assembled in JAPAN . 2009 and 2010 PONTIAC VIBE now added to the list . Cars in CHINA and EUROPE will be recalling vehicles as well . Let's keep our fingers crossed .

I had a throttle problem shortly after i bought the car (08 sedan),every once in a while (2-3 times a week)i'd get no response from the throttle,the car would remain in idle but no amount of pressing the gas peddle would make it do anything else,dealer changed a whole bunch of wires in the engine bay and the problem hasnt returned since

Maybe you could post the work order or email a copy of the work order to the OP. That might help if they are experiencing this.

The work order i got just said wires changed in engine bay The service manager was quit vague about what the mechanic was actually changing and kept assuring me not to worry as its under warranty

Just to put things into perspective......

Down through the years, there have always been cases of repoprted "gas pedal sticking"

Whether all cases have been true or made up in an attempt to divert attention from driver's screw ups we will never know.

Perhaps due to the bad publicity of TBW, we might see a retun to a cable actuated throttles?

No TBW can be good advertising copy for those concernd about the safety and performance of TBW

that will never happen. it is impossible to meet new emission standards without electronic throttle controls except on very limited set of engine designs.

the lag between human foot on a cable to the throttle body vs the electronics
figuring out what you are attempting to do allows too many emissions. having the computer intervene ahead of time ensures the ECU can keep within parameters and never go outside the envelope.

Never say never.

The TBW is more related to MPG, not emissions.
The ECU trying to figure out what you are tring to do is a never ending excersize in futility at best.

If the general public loses faith in the TBW system they, will design TB cable in future designs. It is a buyers market after all.

TBW seemed like a good idea a first but it is not standing up to the test of time.
The auto industry in in the mist or a high tech orgy and perhaps they need to rethink the TBW concept

IMO, throttles should be under the direct control of the driver just like brakes are.

Would you buy a car with a brake by wire sys where your brake pedal is only conected to an electric sensor?
I certainly would not.

I will say never on this. you stomp the gas on DBW, the computer decides
how fast to open it up. this is the only way cars can meet gov regs. gov regs are the issue. I would rather have direct like in my 4runner, but reality is, that is all going away.

drive by wire system are proven to be as reliable if not more reliable than old-school. but they need to be engineered and built properly like anything else, or they can and will fail. brakes will always have a fail-safe mechanism
which is some type of direct braking, in case all other systems fail.

throttle controllers will help.. so far theyre about $125...not gonna make your car any faster but atleast itll get rid of that small annoying lag.

if you.... take off your cats, Change your headers to an after market 421, Change to a straight through Muffler..... and Bore a few holes in your Airbox (before the Filter).... you won't get that "Lag" effect.....
Your LAG effect will turn into a "SURGE" effect....

And you will LOVE the drive.....

Apparently the 'bad' gas pedal assemblies were/are produced here in Mississauga, Ontario, Canada.

The manuf company is also saying that they produced the part according to Toyota specs. I see the lawyers coming out of the woodwork on this one!

In the Toronto Star article Toyota state that it is no fault of the manufacturer. Toyota take full responsibility.

Toyota no doubt engineered the part then tendered it out for production. It would appear to be a design flaw, not a manufacturing defect.

So ... we have the recall here in Europe:

Affected Cars Production
AYGO Februar 2005 - August 2009
iQ November 2008 - November 2009
Yaris November 2005 - September 2009
Auris Oktober 2006 - 5. Januar 2010
Corolla Oktober 2006 - Dezember 2009
Verso Februar 2009 - 5. Januar 2010
Avensis November 2008 - Dezember 2009
RAV4 November 2005 - November 2009
Source: Toyota Cologne, Germany

Sorry, was too lazy to translate everything. Our Yaris is made in France at TMMF, except Yaris TS which came from Japan.

Looks like we did not dodge the gas pedal recal...
