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.
