What brand of mass airflow sensor did you use?

In most cases, it's best to stick to OEM sensors for the best success.

2011 Murano Check engine light on. Code P0101 Mass Flow Sensor - cleaned, light still on. Replaced, light off for 20-30 miles, light back on. Any suggestions?
In my experience, MAF sensors rarely go bad. I had the same error code. Cleaning the sensor didn't help. Dealership cleaned the throttle body and the error code went away.

If you still have the original OEM MAF sensor you should reinstall it as it's likely better than the new aftermarket part that was installed.

As stated previously, this code is rarely caused by a bad MAF sensor. More often it's caused by a vacuum leak. Dirty throttle body is another potential cause among other things. Search these forums for that code as there is extensive discussion about it.
