Fail-Safe System Description

AIR FLOW METER MALFUNCTIONING
If the air flow meter output voltage is lower or higher than the specified value, E.C.U. senses an air flow meter malfunctioning. In case air flow meter malfunctions, the throttle sensor substitutes for the air flow meter.
Though air flow meter is malfunctioning, it is possible to drive the vehicle and start the engine. But engine speed will not rise more than 2,400 rpm in order to inform the driver of fail-safe system operation while driving.
