The Complete Guide To Toyota Gas Pedals: Teardown, Pictures, Toyota's Fix, Analysis, And Commentary
Here’s TTAC’s and the web’s only complete guide to Toyota’s gas pedals (so far), with tear downs, pictures, analysis, explanation, the shim fix, and commentary, all consolidated into one portal:
Part 1: Exclusive: TTAC Takes Apart Both Toyota Gas Pedals: Tear down of both the recalled CTS pedal assembly and the non-recalled Denso pedal assembly. Note: Assumptions and conclusions in this initial tear down lack the more complete understanding of the importance of the friction arm aspect of the CTS unit.
Part 2: Toyota Gas Pedal Fix Explained – With Exclusive Photos: Describes Toyota’s proposed fix for the recalled CTS gas pedal assembly, with detailed photos and graphics. Explains the significance of the friction arm assembly and its limitations.
Part 3: Toyota Gas Pedal Fix Simulated – Friction Reduced, By Too Much?: TTAC simulates the fix prescribed by Toyota for the recalled CTS pedal assembly, and notes how the fix changes the degree of friction, and the possible unintended result. With detailed pictures
Part 4: Why Toyota Must Replace Flawed CTS Gas Pedal With Superior Denso Pedal: Detailed analysis with pictures of the two pedal assemblies, an explanation as to why the Denso design is superior, and a call for having all CTS pedals replaced with the Denso pedal.
Part 5: TTAC Does The Toyota Pedal Shim Fix: Stop Gap Solution At Best: Toyota’s solution is carried out here with detailed pictures, the whole Toyota document detailing the fix, and our commentary.
Part 6: Toyota Floor Mat/Gas pedal Recall Includes Computer Reflash And Trimming Of Gas Pedals: Info on the details of the floor mat/gas pedal interference recall.
Part 7: Toyota Recall Creates Unintended Accelerator Consequences: As predicted in Part 4 (above), the CTS shim fix reduces the carefully designed amount of friction required for comfortable and smooth pedal action to the point where pedal action may now be jerky and potentially unsafe.

- Jeanbaptiste Any variant of “pizza” flavored combos. I only eat these on car trips and they are just my special gut wrenching treat.
- Nrd515 Usually for me it's been Arby's for pretty much forever, except when the one near my house dosed me with food poisoning twice in about a year. Both times were horrible, but the second time was just so terrible it's up near the top of my medical horror stories, and I have a few of those. Obviously, I never went to that one again. I'm still pissed at Arby's for dropping Potato Cakes, and Culver's is truly better anyway. It will be Arby's fish for my "cheat day", when I eat what I want. No tartar sauce and no lettuce on mine, please. And if I get a fish and a French Dip & Swiss? Keep the Swiss, and the dip, too salty. Just the meat and the bread for me, thanks. The odds are about 25% that they will screw one or both of them up and I will have to drive through again to get replacement sandwiches. Culver's seems to get my order right many times in a row, but if I hurry and don't check my order, that's when it's screwed up and garbage to me. My best friend lives on Starbucks coffee. I don't understand coffee's appeal at all. Both my sister and I hate anything it's in. It's like green peppers, they ruin everything they touch. About the only things I hate more than coffee are most condiments, ranked from most hated to..who cares..[list=1][*]Tartar sauce. Just thinking about it makes me smell it in my head. A nod to Ranch here too. Disgusting. [/*][*]Mayo. JEEEEZUS! WTF?[/*][*]Ketchup. Sweet puke tasting sludge. On my fries? Salt. [/*][*]Mustard. Yikes. Brown, yellow, whatever, it's just awful.[/*][*]Pickles. Just ruin it from the pickle juice. No. [/*][*]Horsey, Secret, whatever sauce. Gross. [/*][*]American Cheese. American Sleeze. Any cheese, I don't want it.[/*][*]Shredded lettuce. I don't hate it, but it's warm and what's the point?[/*][*]Raw onion. Totally OK, but not something I really want. Grilled onions is a whole nother thing, I WANT those on a burger.[/*][*]Any of that "juice" that Subway and other sandwich places want to put on. NO, HELL NO! Actually, move this up to #5. [/*][/list=1]
- SPPPP It seems like a really nice car that's just still trying to find its customer.
I am so sick of people like the person who commented above. Toyota has an issue with their vehicles that is a safety related issue and it needs to be fixed. Did the guy who commented above actually read the analysis done in this Blog? If so I guess he did not understand it too well because he is still living under the floor mat with Toyota. I work for one of the automakers and know that we would never try and ignore this issue at ANY cost!!!!
Paul,,,after looking over most of the comments on TTAC it seems obvious to me that few of you understand what the shim does. Part of this is due to incorrect & misleading drawings made by Toyota ( and the A.P.). Installing the shim ELIMINATES the contact between the frictional elements which therefore gets rid of any "sticking" problem and it also ELIMINATES their frictional effects! That is why there are reports of "soft" pedal operation. I will try to explain the pedal operation... the pedal arm pushes against the spring which pushes against the rocker arm, the spring force is reacted at the other end by contact of the friction surfaces which results in drag when the pedal arm moves. When a thick shim is inserted the spring will bottom-out the rocker arm ON THE SHIM and the friction pads will not be in contact! A thin shim would of course have no effect; it's an on or off situation...
