    Default Accelerator Sensitivity

    Hi y'all, new to the board here and have a quick question. I recently purchased my second truck, an '07 Tundra Limited w/ the 5.7L. My first truck was a Tacoma that gave me a trouble-free 224k miles so I love all things Toyota Truck related. So far the Tundra has been great but I do have one concern.
    The accelerator seems to be super sensitive. Just the slightest touch to it and the engine will take off. Its not just me, when my wife and friend first drove it they had the same problem too. I have been able to get used to it but every once in a while my foot will slip and send the truck lurching again.
    Is there anyway to tune this down a little? There is plenty of travel available in the gas pedal, I don't think I have even come close to flooring it. I would like to make it a little less aggressive.

    true.throttle tip in is very sensitive on these trucks and there are no provisions to change that unfortunately.

    You may want to check the history on the truck and see when or if the recall on the gas pedal was done. There was the first fix that involved the installation of a shim which sometimes left the pedal very touchy, then there were two revisions to the pedal itself that addressed that issue. The part number for the latest revision should end with a C, I don't have the exact part number but a search will turn up plenty of threads on the issue and there are a few that have the part numbers.

    My '07 I traded in last month was that was after having the 'pedal' issue resolved. I had been driving it for 2.5 years prior to that and if you even BREATHED on it... you were off to the races. If I would try to say make a u-turn... or pull out into traffic, it would chug like I wasn't giving it any gas. So I'd put it to the floor almost to get it to stop chugging along.

    I'm willing to bet you this is the case. After they did the recal work on mine (shim), the gas pedal was VERY, VERY touchy. I actually felt it was dangerous in some instances. They put the new gas pedal assembly in and I was good to go. I would check into this, you will NOT believe the difference !

    These pedals are touchy from the factory and I hear the shim only made it worse (i.e. the people above).

    The worst is coming from a 4 way stop sign on a rough road. It'll jerk you all around.

    The best thing I've found to remedy the touchy pedal is this..


    HEAVIER TIRES! worked like a charm but after 40K miles of the heavy tires, it still feels sensitive. I can only imagine what it feels like stock again.

    Snap a picture of the accelerator and post it. That way someone here can tell you whether it got the trim and shim fix of the old pedal assembly, or if it already has a new pedal assembly. Basically the pedal will seem a bit touchy if it's an original '07 or the new pedal assembly, but it's bearable. If it's been shimmed, there's a good chance it will feel slightly ridiculous.

    Ironically I find the Gen 1 throttle response to be more aggressive than the 5.7.

    I went digging through the paperwork and found this invoice from the original owners dealership. I cant figure out which part numbers mean which. Do I still need to go in to have the latest version installed?Click image for larger version.

    I would just go into the dealership, tell them about the pedal sensitivity, tell them you feel unsafe with it the way it is and see what they advise...

    If it doesn't have the 440C pedal assy upgrade, ask them to install it...

    I had/have the same problem even after the 440C upgrade pedal. Mine lurches forward too, its so hard to find it's sweet spot. I had the shim done first, then still no luck so they switched out to the newer pedal and it still lurches. I drove around with my service tech and showed him, but he said it's normal for the Tunrda's, they all do it.... I still dont buy that excuse. He drove it as well and it didnt hop around on him, but he drove it a little old lady. Still bugs me, but thats my only complaint in 3 years, so I get by.

    that is the shim "fix"... you need to go to the dealer and complain and get a new pedal
