Not intendign to uestion anybody veracity but all cars have speed limiter based on the tire ratings, except ZR rated.
I don' know what the tire letter rating is for the OEM tire on a Camry but I doubt it is greater than "S" or 112 MPH, at which point the speed limiter, which is set at 5% below the tire rating or around 106 MPH, would kick in.
Cars that have OEM "ZR" rated tires do not have a limiter because few cars can attain a speed as great as that which the tire is capable for running for the one half hour set as the standard. My Mustang has "ZR" rated tires, 'above 149 mph' but it will only do 150 MPH. ( I tested it at Pocono )

For tires having a maximum speed capability above 186 mph (300 km/h), a "ZR" must appear in the size designation. Consult the tire manufacturer for maximum speed when there is no Service Description.
