How to clean the Nissan mass air flow sensor?
Spray 8 to 12 spurts of MAF sensor cleaner on the exposed plate. Allow the MAF sensor to dry and reinstall. Nissan’s mass airflow sensor sends a voltage to the powertrain control module (PCM). The hot wire sensors typically have an operating range of 0 – 5 volts. At idle, the voltage under 1 volt.
Where is the MAF sensor on a Nissan?
Nissan MAF sensor is located right next to the engine air filter housing, typically on the driver’s side. Unplug the electrical connector from your Nissan mass airflow sensor. Watch the following video on how to remove the air filter box to access the MAF sensor.
How is air flow measured on a Nissan D21?
And this measurement of the air flow is sent to the D21’s fuel injection computer as an analog DC voltage signal.
What causes rough idle after replacing mass air flow sensor?
Replaced air filter and maf sensor. Problems with vehicle turning off seemed to go away but now I have a rough Idle. Car will drop below 1000 rpms and then rev back up to over 1500 like it wants to shut off. Idle problems seem to go away when maf sensor is disconnected. Car throwing codes p0171 and p0102.

What happens when a mass air flow sensor goes bad?
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean.
What happens if the mass air flow sensor fails?
As the intake air increases, the voltage from the MAF sensor increases. The truck’s computer uses this signal to determine engine load and adjusts ignition timing and fuel timing for optimum engine performance. If the MAF sensor fails, the computer will go into “limp home” mode and will not allow the engine to run higher than 3,000 rpm.
Where are the MAF connectors on a Nissan D21?
The mass air flow sensor on your Nissan D21 Pick Up has three wires attached to it. You’ll notice that the photos (in the image viewer) have the MAF connectors lettered A thru’ C (if you look closely at the MAF sensor itself on your D21 Pick Up, you’ll see these letters on it too).
Is there a problem with the Nissan mass air flow sensor?
In this guide, you will learn about the Nissan Mass Air Flow (MAF) sensor, a common problem with Nissan MAF, how to diagnose it, replace and carry MAF relearn procedure. This is a list of common symptoms you will notice when your Nissan MAF sensor fails.
How to clean the mass air flow sensor?
Pull the hood release and open the hood. Locate the MAF sensor next to the engine air filter housing. Unplug the mass air flow sensor electrical connector. Remove the two screws that hold the MAF sensor secure and remove the MAF sensor. Spray 8 to 12 spurts of MAF sensor cleaner on the exposed plate. Allow the MAF sensor to dry and reinstall.
How to test the Nissan MAF sensor in Spanish?
How To Test The Nissan MAF Sensor: Sentra 1.8L 4 cyl. (2000-2002). You can find this tutorial in Spanish here: Prueba: Sensor de Flujo de Aire (MAF) 2.4L Nissan D21 Hard Body (1990-1995) (at: autotecnico-online.com ). This list covers the majority of symptoms I’ve seen with this type of Nissan mass air flow sensor:
The mass air flow sensor on your Nissan D21 Pick Up has three wires attached to it. You’ll notice that the photos (in the image viewer) have the MAF connectors lettered A thru’ C (if you look closely at the MAF sensor itself on your D21 Pick Up, you’ll see these letters on it too).
How do you clean an air flow sensor?
Set the screws in a safe place; then remove the air-cleaner duct or air-intake assembly to reach the sensor inside the system. Depending on the model of your vehicle, you might need to remove one or more clamps using a standard or Phillips-head screwdriver, or disengage wire clips to take the air-intake assembly apart.
How to tell if your air flow sensor is bad?
Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.

What’s the best way to clean a MAF sensor?
Spray the MAF sensor wires or grid (sensing elements) with electrical component cleaner or MAF sensor cleaner. (See Tips for more information.) Rub dirt and contaminants off the sensor elements using a soft brush, until the wires and sensor components are completely clean.
