Abstract: 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.

Abstract: An electronic device controlling the intake manifold heater and priming fluid injection system in diesel engines. The device automatically energizes the intake manifold heater and enables the priming fluid injector in response to electrical signals received from a coolant temperature sensor and a lubricating oil pressure sensor so as to improve cold starting, cold driveability, fuel consumption, gas emissions, and to eliminate white smoke at the exhaust. The device prevents the priming fluid injector from being operated until after the intake manifold heater has cooled to a level preventing ignition of the priming fluid, such as ether, in the intake manifold.
