What can a Nissan Quest mass air flow sensor do?
A defective Nissan Quest mass airflow sensor could make your car difficult to start. Your ECU uses the mass airflow sensor input to determine the fuel ratio that the injectors need to deliver to the engine. If your check engine light is still on, use an OBD2 scanner to clear any stored codes in the ECU.
What is the fault code for Nissan mass air flow sensor?
Fault codes such as P0171 System Too Lean (Bank 1), P0174 System Too Lean (Bank 2), and P0101. Dirty, obstructed, or faulty mass air flow sensor. Write down these codes research them to find out what each code means. Replacing the MAF sensor on a Nissan vehicle is very easy.
When to pay attention to your mass air flow sensor?
It is common for mass air flow sensor get dirty and get failing, so pay attention on your mass air flow sensor is any symptom happen as following: if the Check Engine Light is on; if your Nissan car doesn’t have power; if there is an excessive fuel consumption; if your Nissan car fails at starting.
Where is the diagnostic port on a Nissan?
Locate the diagnostic port under the dashboard on the driver’s side. Plug your diagnostic scanner in this port. Turn on the ignition but do not start the engine. Allow your scanner to turn on and communicate with the ECU.

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.

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.
Why is my Nissan mass air flow sensor not working?
by Dan Ferrell. The mass airflow sensor (MAF) in your Nissan vehicle measures the amount of air going into the engine. If the MAF sensor sends the wrong signal to your car’s computer–because of dirt or other contamination around its sensing elements–your engine will be fed with the wrong amount of air/fuel mixture.

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.
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 reprogram a Nissan air flow meter?
ASE Master technician. 25+ years general automotive experience Most 2000 model year Nissan’s need ECM reprogramming after air flow meter replacement. The parts department that sold you the part can see if there is a tsb when they pulled up the part number.
What should I do if my ECU has been reset?
Turn the ignition to the “On” position but don’t crank the engine (it won’t start anyway). Wait five minutes and reinsert the fuse. The “Check Engine” light will blink, then shut off. This will indicate that your ECU has been reset. “Auto Repair For Dummies”; Deanna Sclar; IDG Books Worldwide; 1999
What is the diagnostic code for a Nissan?
Nissan Diagnostic Fault Codes List. Nissan Logo. P0100 Airflow Circuit Malfunction. P0101 Wrong indicator / air flow meter not adjusted. P0102 Low air mass meter reading. P0103 High air mass meter reading. P0104 Malfunction of the air mass meter.
What should I do if my Nissan p0101 code comes back?
P0101 NISSAN Tech Notes Before replacing the Mass Air Flow (MAF) Sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replace the mass air flow sensor.
What does the p0101 Nissan MAF sensor mean?
P0101 NISSAN Meaning The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM). The temperature of the hot film is controlled by the ECMa certain amount.
When to replace the mass air flow sensor?
Before replacing the Mass Air Flow (MAF) Sensor, try replacing the air filter and cleaning the Mass Air Flow sensor with low compress air or Mass Air Flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replace the Mass Air Flow sensor.
What does low idle mean on a Nissan?
1. Stuttering/low idle/near stall/stall when stopped in gear 2. Upon warm restart, engine idle would drop below 500 rpm and almost stall, 3. When cold, at light throttle input, a stumble/stutter around 1,700 rpm that almost felt like a transmission slip. 4. When cold and in 5th gear but low speed of around 40 mph, the car actually bucked.
Is the idle issue on the Nissan EX35 solved?
Idle issue & stutter solved! Discussion of Infiniti’s amazing (and underrated) sport-luxury crossovers, the EX35 and EX37. For 2014, the EX series will be renamed QX50, in line with Ininfiit’s new naming conventions.
What causes a car engine to sputter with low fuel pressure?
If your fuel pressure is too low, there is definitely something wrong with either the fuel filter or the fuel pump. If there is a leak around the intake manifold or at the hoses from the intake manifold, it may cause a too lean mixture, which will cause your car engine to sputter. The easiest way to find this is to use an EVAP smoke machine.
What to do if your car engine is sputtering?
The seals and gaskets prevent exhaust gases and oil from finding their way to the combustion chambers. When these fail, you will start experiencing a sputtering engine. Further seal damage will eventually lead to the complete destruction of the exhaust manifold. The solution to this is to simply replace the seals and gasket if you find any leaks.
