Ameetaa Mass Air Flow Sensor MAF AFH55M12 for Nissan 2.4L L4 (1996–2004) - 3-Pin Direct Replacement, Durable Fit

Ameetaa's Mass Air Flow Sensor AFH55M12 accurately measures incoming air for 2.4L L4 Nissan Pickup, Frontier, and Xterra model years listed, providing reliable airflow data to your engine control unit.

This direct-replacement MAF sensor is designed to fit specific Nissan 2.4L L4 engines from 1996 through 2004, matching the AFH55M12 and related OEM numbers. Constructed from durable plastic and aluminum with a three-pin connector, it restores correct air-volume and air-density readings that the ECU needs to adjust fuel delivery and ignition timing. Before installing a new MAF, clear the airbox and fit a fresh air filter to avoid lingering check-engine codes caused by contamination.

How will this MAF sensor affect engine performance?

Replacing a worn or failing MAF sensor helps the ECU receive accurate airflow measurements, which can normalize fuel trim and improve throttle response. While not a guaranteed cure for all drivability issues, installing a proper MAF for your vehicle often resolves rough idle, hesitation, and irregular acceleration tied to air-measurement errors.

• Restores accurate air-volume and air-density readings for the ECU
• Helps stabilize idle and throttle behavior when airflow data was incorrect
• Specifically matched to Nissan 2.4L L4 models for correct fit and function

Which vehicles and part numbers is this compatible with?

This Ameetaa MAF is engineered to be a compatible replacement for 1996–1997 Nissan Pickup, 1998–2004 Nissan Frontier, and 2000–2004 Nissan Xterra equipped with the 2.4L L4 engine. It corresponds to several OEM references so you can cross-check fitment before purchase.

• Compatible model years and vehicles: 1996–1997 Pickup, 1998–2004 Frontier, 2000–2004 Xterra
• Replaces AFH55M12, AFH55M-12, 160171S710, 16017-1S710, 160173S500, 16017-3S500
• Three-pin connector and front placement match original equipment specs

What should I do before and during installation?

Clean the airbox and install a new air filter prior to fitting the sensor to prevent false codes and premature sensor fouling. Disconnect the battery, unclip the electrical connector, remove the old MAF, and install the replacement making sure seals and mounting points are snug.

• Replace air filter and vacuum-clean the airbox first
• Disconnect battery and unplug the three-pin connector before removal
• Secure sensor mounting and check for air-leaks after installation

How durable is the Ameetaa replacement MAF?

The housing uses plastic and aluminum to balance weight and strength while protecting the sensing elements from heat and vibration. Proper vehicle maintenance—clean airbox, fresh filter, and correct installation—will extend service life and reduce the chance of recurring check-engine lights related to airflow measurement.

• Plastic/aluminum construction resists engine-bay conditions
• Three-pin electrical interface matches factory wiring harnesses
• Designed to provide stable readings across typical ambient temperatures

Who is this for: Ameetaa's AFH55M12 Mass Air Flow Sensor is intended for owners and mechanics of 2.4L L4 Nissan Pickup, Frontier, and Xterra models from the listed years who need a direct-fit replacement to restore correct airflow data. If your vehicle exhibits erratic idle, hesitation, or a persistent airflow-related trouble code, and you've already verified the airbox and filter, this MAF sensor is a practical, OEM-referenced replacement option.
