Abstract: A method of monitoring pressure of oil that is implemented within an internal combustion engine includes determining an expected oil pressure value based on engine operating conditions and monitoring an actual oil pressure value based on a signal generated by an oil pressure sensor. A difference between the expected oil pressure value and the actual oil pressure value is calculated and is compared to a threshold difference. A diagnostic trouble code is generated when the difference exceeds the threshold difference.

Abstract: A method of determining diagnostic limits for a vane position sensing system installed in a variable nozzle turbocharger (VNT). The method includes defining mechanical input probability distribution functions (PDFs) of the VNT, describing the vane position sensing system in terms of component models and defining component parameter PDFs for parameters associated with the component models. Vane position signal PDFs based are generated on the mechanical input PDFs, the component models and the component parameter PDFs, and diagnostic limits are set for the vane position sensing system based on the vane position signal PDFs.

Abstract: An engine oil change detection control system is provided. The system includes an armature position module that monitors a solenoid armature position based on a position signal. A solenoid control module selectively generates a solenoid control signal and estimates a delay time based on the solenoid control signal and the armature position. An engine oil change detection module detects an engine oil change event based on the delay time.

Abstract: Ein System für ein Fahrzeug umfasst ein Auslösemodul, ein Kraftstoffsteuermodul und ein Zylindersteuermodul. Das Auslösemodul erzeugt einen Auslöser, wenn eine Maschinendrehzahl größer als eine erste vorbestimmte Drehzahl ist. Die erste vorbestimmte Drehzahl ist größer als Null. Das Kraftstoffsteuermodul stellt Kraftstoff zu Zylindern der Maschine in Ansprechen auf die Erzeugung des Auslösers ab. Das Zylindersteuermodul sperrt selektiv ein Öffnen von Ansaug- und Abgasventilen der Zylinder in Ansprechen auf die Erzeugung des Auslösers, nachdem der Kraftstoff abgestellt ist.
