A-Premium Mass Air Flow Sensor MAF for Nissan & Infiniti — 5-Pin Direct Replacement, ±2% Accuracy

The A-Premium 5-pin Mass Air Flow (MAF) sensor measures incoming air volume and density so your Nissan or Infiniti engine control unit can calculate proper fuel delivery.

This direct-replacement MAF sensor from A-Premium is an aftermarket bolt-on unit engineered to match factory fit and function for many Nissan, Infiniti and a few compatible models. Built from PBT+GF30 and aluminum alloy with a 5-pin connector, it reads airflow from 0 to 560 kg/h with ±2% accuracy and supports a maximum supply voltage of 17 volts. The sensor replaces a variety of OEM reference numbers and is intended for technicians and DIYers who need a reliable, cost-effective MAF swap.

How do I know this MAF sensor fits my vehicle?

Confirm fitment by matching your vehicle year, engine size, and the OEM reference number listed for the part. This A-Premium unit covers a wide range of Nissan and Infiniti models across multiple years and engines; check the exact model compatibility before purchasing to ensure a correct plug-and-play fit.

• Compare OEM reference numbers (e.g., 226807S00A, 22680-7S000).
• Verify engine displacement and production years against the fitment list.
• Confirm connector type: 5-pin pin-style terminal, 2 bolt holes, bolt-on mount.

What performance and specifications should I expect from this MAF sensor?

The sensor provides a precise air-mass measurement range up to 560 kg/h with ±2% measurement accuracy, enabling stable fuel trims and smoother idle. It accepts up to 17 volts and combines durable PBT+GF30 plastic with aluminum alloy internals for corrosion and heat resistance.

• Terminal quantity: 5 pin connector for OEM electrical compatibility.
• Mounting: two-bolt bolt-on design for direct replacement.
• Material: reinforced plastic housing and aluminum components for longevity.

What symptoms indicate I should replace the mass air flow sensor?

A failing MAF sensor can trigger a check engine light and cause drivability issues such as rough idle, hesitation, or poor fuel economy. Scan for codes related to airflow or fuel trim, and inspect for contamination or wiring damage before replacing; replacing a faulty sensor typically restores stable air-fuel control.

• Common signs: rough idle, stalling, reduced acceleration, and increased fuel consumption.
• Diagnostics: read OBD-II trouble codes and compare live MAF readings against expected values.
• Simple checks: inspect connector, wiring harness, and air filter for leaks or contamination.

How should I install and maintain an aftermarket MAF sensor?

Installation is straightforward for anyone familiar with basic engine bay work: disconnect the battery, unplug the old sensor, remove two mounting bolts, and swap in the new sensor, then clear stored codes. Maintain performance by keeping the air intake and filter clean and avoiding harsh cleaners or touching sensor elements.

• Installation steps: battery disconnect, unplug 5-pin connector, unbolt, replace, reconnect, clear codes.
• Maintenance tips: replace air filter regularly and avoid contaminating the sensing element.
• Recommendation: verify codes with a scanner or consult a qualified mechanic before replacement.

Who is this for: The A-Premium 5-pin MAF sensor is designed for owners and mechanics who need a reliable, OEM-style replacement for numerous Nissan and Infiniti models (and several compatible vehicles). It suits drivers looking to restore normal engine performance, address OBD-II airflow codes, or service routine maintenance with a cost-effective aftermarket option backed by a one-year unlimited-mileage guarantee.
