DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P0100-64	Mass or Volume Air Flow Sensor "A" Signal Plausibility Failure	All of the following conditions are met (2 trip detection logic). The engine is running. The engine coolant temperature is 70°C (158°F) or higher. The throttle position sensor voltage is 0.2 V or higher, and less than 2 V. Average engine load value ratio is less than 0.85, or higher than 1.15 (varies with estimated engine load). Average engine load value ratio = Average engine load based on mass air flow meter sub-assembly output / Average engine load estimated from driving conditions Average air fuel ratio is less than -5%, or higher than 10%.
