Code result

P0104

Mass or Volume Air Flow Circuit Intermittent

Moderate severity

What it means

The ECU detects intermittent signal dropouts or noise on the mass air flow (MAF) sensor circuit. The fault is not constantly present, suggesting a loose connection, intermittent wiring break, or a failing sensor under specific conditions (vibration, temperature).

Is it safe to drive?
