Code P0101 2000 Toyota Echo Description

The P0101 diagnostic trouble code (DTC) for a 2000 Toyota Echo indicates a Mass Air Flow (MAF) Circuit Range/Performance Problem. The MAF sensor is a critical component of the vehicle's engine management system, as it measures the amount of air entering the engine to determine the correct air-fuel mixture for combustion. When the MAF sensor detects that the air flow is outside the expected range or is not performing within specified parameters, it triggers the P0101 code.
