System and method of detecting vehicle speed limiting system tampering

A system for detecting vehicle speed sensor tampering in a vehicle, comprising:

• an engine control module;
• a global positioning receiver operatively connected to the engine control module;
• a clock operatively connected to the engine control module;
• the engine control module learning a first position from the global positioning receiver;
• the engine control module learning a first time from the clock;
• waiting a period of time;
• the engine control module learning a second position from the global positioning receiver;
• the engine control module learning a second time from the clock;
• the engine control module calculating the average vehicle speed;
• the engine control module comparing the average vehicle speed to a predetermined value corresponding to a speed limit value stored in the engine control module and generating a tampering signal if the average vehicle speed is greater than the speed limit value;
• the engine control module checks the operation of the global positioning system if the average vehicle speed is not greater than the maximum vehicle speed to determine if the global positioning system was tampered with or disabled and generating the tampering signal wherein the average vehicle speed is determined to be less than the maximum speed if the first position signal and the second position signal correspond with the same position or if the first position signal and the second position signal are not received from the GPS;
• and
• the engine control module limiting engine speed in response to the tampering signal being generated.
