P0101 — Mass air flow sensor: range/performance

Severity: Attenzione Can you drive? Sì, no known limitation Produttore: Tutti makes (OBD-II standard)
MeaningThe MAF sensor measures how much air enters the Motore. When its Valore does not agree with the Altri sensors, the ECU notices and sets this code.
FamilyPowertrain (P)

Typical symptoms

Reduced Potenza
Higher fuel consumption
Unstable idle
Black smoke under acceleration

Common causes

Dirty oppure badly fitted air Filtra
MAF fouled with oil (often Da oiled sport Filtri)
Air leak downstream di the sensor
Aged sensor out di calibration

What a do

Check Filtra and hoses Prima: an air leak after the MAF produces exactly this code. Cleaning the sensor with a dedicated Prodotto is often enough; if the Lettura stays out di range on the diagnostic tool, replace it.
