What is mass or volume airflow circuit?
The mass airflow (MAF) sensor is a device that is mounted on the air intake. Its job is to measure the density and, therefore, the volume of filtered air that is drawn into the engine. When the PCM perceives the sensor or its circuit is malfunctioning, OBD-II code P0101 is triggered.
What does p0101 mean on the Nissan Pathfinder?
With the Nissan Pathfinder, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem. We will cover exactly what that means and potential fixes for it below. It should be considered a high priority to fix, as the MAF sensor not reading properly can really make an impact on the performance of the vehicle.
Where is the mass air flow sensor located on a Nissan?
P0101 NISSAN | Mass Air Flow Circuit Range/Performance | 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 The Mass Air Flow (MAF) sensor is placed in the stream of intake air.
What is the trouble code for the MAF sensor?
The troublecode P0100 is set when the MAF sensor circuit is malfunctioning. This code is similar to P0104 – MAF sensor circuit intermittent. The difference between the two codes is the consistency of the malfunction in the MAF sensor circuit. Troubleshooting will be the same for both codes.
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.
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.
With the Nissan Pathfinder, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem. We will cover exactly what that means and potential fixes for it below. It should be considered a high priority to fix, as the MAF sensor not reading properly can really make an impact on the performance of the vehicle.
What makes a Nissan Pathfinder not shift into 3rd gear?
1997 Nissan Pathfinder. Won’t shift into 3rd gear. Giving codes 100 mass air flow, 325 knock, 120 throttle position switch, 1447 no des. Shifted properly until I starting working on the sensors?
