P0101 Honda Code - Mass Air Flow Circuit Range/Performance
Quick Answer
The Mass Air Flow (MAF) sensor is attached to the intake air passage, and it measures the amount of intake air flow. Common causes include Faulty Mass Air Flow (MAF) Sensor, Mass Air Flow Sensor harness is open or shorted, Mass Air Flow Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
