2012 nissan versa mass air flow sensor problems

Here’s a fantastic video on how to diagnose a bad MAF sensor using a multimeter from Ratchets and Wrenches on YouTube. There are other codes related to the mass air flow sensor as well, but these are the most common ones.

Nissan Versa P0102: MAF Sensor Circuit Low.

Nissan Versa P0101 Diagnosis: MAF Sensor.

The two most common trouble codes in relation to the MAF sensor are: This is great because it helps you narrow down the problem. If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code. Here a couple of common MAF sensor styles

Decreased Fuel Mileage– Fuel mileage can suffer without the proper air/fuel mixture.

Also, jerking can be caused by bad spark plugs or coil packs. It’s bad for your motor mounts when this happens.

Jerking– As you go down the road, you’ll feel your Versa really jerk and hesitate as the engine speed changes erratically.

And when it does, it doesn’t usually run very well.

Hard to Start– Without knowing the proper amount of air entering into the intake, it can be really difficult for the engine to start.The exhaust color usually doesn’t change. A lean condition is when there is too much air relative to fuel in the air fuel mixture. The exhaust color is usually darker when running rich. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. Idle Issues– Your Versa may run rich or lean when idling, or it may also idle erratically.Here are the most common symptoms of a bad or failing MAF sensor: When the mass airflow sensor has gone bad, you’ll definitely feel it. And, most of the time they are right by the air box and easy to replace.įaulty Mass Airflow Sensor Symptoms: Nissan Versa If you do determine that you need a new mass airflow sensor, they aren’t too expensive. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber. It passes this information onto your Versa’s ECU.

A bad mass airflow sensor can leave your Nissan Versa’s engine running rough, or even inoperable.Ī MAF sensor measures the density of the air entering the intake manifold. The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors.
