A method and apparatus for executing a strategy of electronic throttle monitoring of a powertrain system including an electronic powertrain control module, and an electronic throttle control, includes an independent processor receiving signals shared with the powertrain control module from sensors and actuators on the vehicle. The monitor operates in a monitoring mode to detect faults occurring in the powertrain or the powertrain control module, and determines whether mitigating conditions occur in conjunction with detected power output greater than power demand. In the event that these mitigating conditions are not detected, the monitor operates in a limiting mode to actuate decreases in power output below the level of power demand.

An electronic throttle monitor for a motor vehicle powertrain system with an electronic throttle control and a powertrain control module (PCM) including a main processor comprising: a processor independent of the main processor, said independent processor ordered to perform a monitoring function in a first operating mode including reading a set of powertrain sensors and communication interfaces shared with the PCM and determining when detected power is greater than demanded power; said processor being programmed to perform a limiting function in a second operating mode for limiting detected power to less than demanded power when detected power is greater than demanded power.
