Is Toyota's "fix" for the accelerator pedals going to work?

    I keep reading about how the recall fix for the accelerator pedals involves placing a "spacer" or some other mechanical component in the pedal assembly to keep it from sticking. However, many people seem to think that from reading accident reports the evidence points to the problem being a computer software issue. If that's the case, it seems to me that the true fix should involve a firmware update or some other effective replacement of the current software controlling the accelerator.

    Does anyone else think this is the case and that Toyota is going to have to recall all these vehicles again when the real problem surfaces?

    Also, in relation to the Tacomas, did the floor mat recall actually fix anything? Or was this another example of Toyota scratching its head and not knowing what the actual problem was?

    To summarize the questions ... do you think that the accelerator pedal-stick problem is a general computer issue affecting many or all Toyota models including the Tacoma, and that this will eventually result in another mass recall that includes the Tacoma?

    Welcome to the board- You could probably have posted up some sort of introduction before diving right into the recall problem...and there are a TON of other threads about this.

    Only time will tell as the company/gov't investigate further and figure out what is going on.... So your guess is as good as anyone elses.

    Do I think it's throttle by wire? No. Toyota runs a dual sensor system that requires redundancy between the two sensors to determine the throttle position. If one or both sensors differ from each other the throttle is almost completely disabled so that the car can be "limped" home or to a dealer.

    For the throttle by wire system to go crazy both sensors would have to detect that the pedal is being depressed and "stick" in that position.

    maybe it IS a software problem, they don't want to admit it, and will fix the code while the car's pedal is getting worked on!

    If it was a software problem you would be able to re-create the issue in every vehicle running that variant of the FBW software. Since it is limited to so few vehicles it is easy to say it is a QC issue.

    There sure seems to be alot of people pointing their fingers in different directions. Like already mentioned, time will tell. With all the different reports of how this problem arises (while at a dead stop, while driving, when the cruise control is engaged) it kinda makes you wonder...

    The last time I heard...the Tacoma is not included in the pedal recall.
    The tacoma has a different pedal assembly than their other vehicles.

    I thought I read somewhere that the Tacoma finally fell under the recal. It was posted on here and had a link to a news website I think. Ill see if I can dig it up.

    Wouldn't it be easier just to admit it's a software problem and just reflash the ECU ? They're doing that with the 2010s transmission ECU, would be a lot cheaper and faster.

    Toyota all weather floor mats. Mag light that clunks around in the jack compartment. Dog hair. Dog drool on the windows.
    I think the problem is major league baseball satellites beaming mind controll rays to earth.

    I got a letter stating that the Tacoma is included and they will reshape my pedal for me.

    thats for the floor mat recall not the sticking pedal recall totally different

    Tacomas are not involved in the recent recalls, I got a letter as well about the re shaping. its a different recall all together.

    no worries

    I believe its a different type of pedal fix. The Tacoma one is an issue with the floor mats and the pedal being too long. The other issues is with the pedal going back to its normal spot, which is why a shim is needed. There is a site you can check to see if your vehicle is affected. For instance, the Corolla's that have a vin beginning with a J are not affected.


    EDIT: Damn I'm slow... beat by 3 minutes

    I've looked for more info on the throttle sensor--do you have a source for details of its operation? Is it two identical sensors in the pedal assembly, or is it two different types (potentiometer and optical, for example)?

    You may recall that when the F22 Raptor made its first flight across the International Date Line, a lot of the on-board computers went berzerk and shut down. Programming error buried in the control code.

    The problem with computer program errors is that it can be a very specific set of circumstances under which it occurs, and if you don't precisely replicate the circumstances you might not catch it.
