New Mass Air Flow Sensor Meter For Nissan Sentra/Tsuru NX & Infiniti G20:1991-96

Mass Air Flow Sensor for Nissan Sentra, Tsuru NX and Infiniti G20

This mass air flow sensor measures the volume of air entering the engine so the fuel injection system can deliver the correct air-fuel mixture, serving as a direct replacement for the factory meter on 1991 through 1996 applications.

Overview

This mass air flow sensor meters intake airflow and sends that signal to the engine control unit for accurate fuel delivery. It is a practical replacement for a failed or contaminated meter on the listed Nissan and Infiniti models. Installers and DIY owners working on 1991-96 vehicles will find it a straightforward fit.

• Measures intake air volume for correct fuel injection timing and mixture
• Housing and connector designed to match the original mounting points
• Plug-in electrical connection for a direct swap with the old sensor
• Sealed sensing element protects against dust and oil contamination
• Built to restore stable idle and throttle response after a meter failure

Fits These Machines

• for Nissan Sentra 1991-1996
• for Nissan Tsuru NX 1991-1996
• for Infiniti G20 1991-1996

On-The-Job Use

• Replacing a failed meter that causes rough idle or hesitation
• Restoring correct fuel trim after a check engine light for lean or rich codes
• Routine maintenance on high-mileage 1991-96 Nissan and Infiniti engines
• Diagnostic repair when airflow readings drift out of specification

Specs At A Glance

Good To Know

Q: Will this sensor fix a rough idle? A: A faulty mass air flow sensor is a common cause of rough idle and hesitation, and replacing it often restores smooth running when the old meter is the confirmed fault.

Q: Do I need to reset the ECU after installing it? A: Disconnecting the battery for a few minutes before installation clears stored fuel trim values so the control unit can relearn with the new sensor.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
