This code is telling you there is an issue with the mass air flow sensor.

However, this could just be a vacuum leak which is most likely what they found with the intake gaskets.

So, the way to test this to find what they did is to follow this guide:

However, this could be a MAF sensor issue itself so we will need to run through the voltage testing and check for shorts to find out if the voltage is the issue.

Please see the attached info below. If there are no vacuum leaks, then the most likely issue is the sensor. However, it could also be wiring or a PCM.

Please run through this info and let us know what you find with this, and we can go from there.

Thanks
