Engine Over Speed Monitor
Engine Over Speed check is performed continuously during each drive cycle. The function detects engine overspeed when a certain calibratable engine-speed threshold has been exceeded for certain period of time; this malfunction criteria sets. This monitor is set not to heal during same drive cycle.
