Spectra Premium MA140 mass air flow sensor for the 2002-2003 Nissan Maxima V6 3.5L and other vehicles measures the air flowing into the engine.
A rough idle, poor fuel economy or a check engine light can mean the sensor is failing. Before you replace it, rule out a cracked or loose intake duct, a clogged air filter and an air leak after the sensor, since each can give similar symptoms. This listing is one sensor, and each engine takes one.
This is a direct-fit replacement mass air flow sensor for the 2002-2003 Nissan Maxima V6 3.5L, the 2002-2004 Infiniti I35 V6 3.5L and the 2003 Infiniti G35 V6 3.5L.
