No there are 3 threads here. 1. Floor mats interfering with throttle mechanism 2. Throttle mechanism sticking – this is the design from CTS 3. Throttle by wire like in my Prius
The EMI issue is with number 3. Could EMI interfere with communications between throttle sensor to CPU or CPU to motor? There are a number of cars with Throttle by wire, none that I am aware of that brake or steer totally by wire. Yes I am aware of electric brakes on trailers …..

However, I believe that this isn’t the proper approach. 1. The problem may have occurred before CTS started making the accelerator pedal assemblies. Toyota has had unintended acceleration issues for quite a while with it only recently being publicized. 2. If EMI is an issue, it may have nothing to do with CTS. CTS only makes the mechanical assembly, not the electronics. 3. CTS manufactured the assembly to Toyota’s design and specification. Toyota reviewed the parts and performed incoming inspection. I spent time in a rubber vulcanization facility in Fort Wayne, Indiana. The plant made the rubber gaskets for doors, sun roofs and trunk lids. It supplied Ford, Toyota and Honda. Toyota regularly rejected shipments because they didn’t meet the incoming inspection requirements. The same would have happened if the accelerator assemblies didn’t meet Toyota specifications. You can call it a questionable part, but it isn’t the manufacturer’s fault unless they were violating Toyota’s specifications and intentionally deceiving Toyota. Every indication is that the parts were made exactly as Toyota had specified. I am not trying to be too negative towards Toyota. I am only stating that the manufacturer of a product has the ultimate responsibility for the problem. Passing the blame isn’t going to fix things.
