Standard Ignition Mass Air Flow Sensor P/N:MAS0491
Standard Ignition MAS0392 mass air flow sensor for the 1996-1999 Nissan Sentra 4-cylinder 2.0L and other vehicles measures the air entering the engine and reports it to the ECU. Those readings help the ECU balance the air/fuel ratio for clean burns.
A rough idle, hesitation or a lit check engine light can have a failing mass air flow sensor behind it. A vacuum leak, a clogged air filter or a tired oxygen sensor can produce those signs too, so find which one is at fault before you buy.
As a mass air flow sensor replacement for the 1996-1999 Nissan Sentra 4-cylinder 2.0L, it is a direct-fit OE replacement. It also fits as a mass air flow sensor for the 1991-1996 Infiniti G20 4-cylinder 2.0L and the 1995-1998 Nissan 200SX 4-cylinder 2.0L, and the quantity is one per vehicle.
