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🙏🏼

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.

Al cambiarlo se duplicaron las millas antes de la recarga de combustible, obtenía 100 millas al llegar a 1/4 de tanque y con el sensor nuevo llegó a 210 millas antes de llegar a 1/4 de tanque.

Was recently having some issues with the car randomly stalling and idling problems. Been chasing this problem for about 5 months now. Damage to the old MAF was caused by a mechanic that did some valve cover work, which was very horribly done. Code that was always flipped was the P0300, which can be basically anything, so its hard to chase electrical issues. But this may finally have solved it! Played around with the old MAF, and there were signs that it was the problem. This sensor worked right away, plug and play basically. This is a new brand name of Hitachi, called Astemo now. Made in Japan, and it is the OEM manufacturer for the car. So far no issues, great product, and I hope for it to work long term. Overall 5/5! Luckily I did not get a used/old product as some others have said. This was brand new in package. Car is a 2012 Nissan Versa 1.6L. I added a picture of the compatible cars that is in the package.

I bought it the last January 13 2021, and today October 17, 2022 the sensor doesn't work anymore, so almost two years it worked. The Original worked for 6 years, so I need to buy I new one and I thinking to buy the original part.
