The mass air flow sensor on your Nissan Pathfinder needs to be working in peak condition all the time. Because of its function of regulating fuel-to-air ratio for your engine, constant maintenance must be done if you do not want to have any performance or mileage issues. With that in mind, here are a few maintenance tips for you to start taking care of it:
Remove/Reinstall mass air flow sensor properly.
The mass air flow sensor is located under the hood, just behind the air intake area. It is therefore important that you should know how to remove the part in a correct manner. Failure to do so would result in a wire suddenly snapping or the mass air flow sensor getting damaged. Determine how the part is being held in place. It is usually a choice between bolts, screws, or metal clips. There is also a wiring harness installed in the unit. Simple car tools such a flat-head screwdriver are necessary for easy removal.
Scan engine regularly.
A great precaution to do for your vehicle's mass air flow sensor is to scan it using a digital scanner. This device could easily be bought at any auto parts store, and are simply plugged into the circuit box. Once turned on, it reads the computer data the car has and displays a bunch of numeric codes. There is always a reference book that comes with the scanner, and that would tell you if the mass air flow sensor is having any trouble.
Clean mass air flow sensor carefully.
When cleaning the mass airflow sensor, use the appropriate mass air flow cleaner housing cleaner or any electronic parts cleaner. Make sure to apply it on every single component of the sensor. After spraying, wipe off any excess cleaner with a smooth towel or cloth. If there is a dirt clump that seems to stick even after wiping, just let it sit for a few minutes, then spray it before trying to wipe it off again. Never, in any way, use a hard brush or any abrasive material. The mass air flow sensor is made up of very delicate and sensitive parts. Harming them in any small manner would cause the part to completely malfunction, forcing you to replace the whole part.
