Fixed my vehicle. Easy to install.
My engine check light went off because of this great mass air flow sensor. It's the best price I found online or at the local auto parts store. It works with my car. The quality is excellent since it's the original factory part that came out of my car.

Solved My Engine Shutdown Issue – Perfect Fit for 2005 Nissan Murano
I was experiencing a dangerous issue with my 2005 Nissan Murano: the engine would randomly shut off while driving, especially when coming to a stop or slowing down. After some troubleshooting and attempts to clean the original MAF sensor, I decided to replace it with this Hitachi sensor, and the issue was resolved immediately. Since installing this MAF sensor for myself, the engine runs smoothly, the idle is stable, and it hasn’t shut off once. This part is clearly OEM-grade, fits perfectly, and no additional setup is required. It restored full reliability to the vehicle. If you’re dealing with engine stalling or shutdowns, this sensor is highly recommended. Don’t waste time trying to fix a failing sensor—replace it with Hitachi and drive with peace of mind.

Good MAF sensor
I bought this MAF sensor for my 2012 Nissan altima, started malfunctioning with low RPMs not going over 2500 I got it scanned at autozone and the diagnosis was the one I attached on the picture, code P0101 and a few more,I replaced the MAF sensor with this Hitachi one and it cleared all the codes and it's working good after 3 weeks,you need to disconnect the battery before installing the sensor to reset the computer,reconnect the battery after 10-15 minutes, God bless you🙏🏼

OEM sensor, w/ tutorial on how to put it on correctly
100% OEM, turned off engine light as soon as i plug it in, really cheap and fast shipping, worked with my nissan murano 2005, should work for most cars of the same v6 engine. Just make sure you disconnect the battery for 10-15 minutes and once the time is up you honk the horn or turn on the lights to make sure the whole system is drained of power. Then replace the sensor using a T20 tamper proof bit, make sure the sensor faces the same way as the old one, the little glass wires should face away from the throttle body, and towards the intake filter. Hand tighten the screws, then plug in the battery and start the car up. Worked perfectly for me.

New brand for Hitachi is now Astemo Hitachi
Installed and everything working great. One thing i noticed is box and sensor says Astemo instead of Hitachi. Papers inside says the new company is now called Astemo Hitachi now. Well see if I encounter any issues later, but so far everything is working fine.
