Just popped a code for this. On route to look at another car. Is this dangerous to drive as is? I'm thinking not but figured I'd check Just cleaned the throttle body a few weeks ago and did remove the sensor
Possibly you damaged the MAF meter when you took it out, or when you had it out. Possibly inadvertantly. Go through the inspection procedure and see where it takes you. As far as is it dangerous to drive, probably not but it should be addressed sooner rather than later. DTC P0101 | Mass or Volume Air Flow Circuit Range/Performance Problem | Inspection Procedure I hope that helps.
I pulled the MAF I inspected it Sprayed it down with electrical cleaner Also did this to the connectors The little glass piece on it looked quite dirty I reinstalled it and cleared the code which didn't come back I also ordered a new MAF sensor
The little glass piece should only ever be cleaned with spray cleaner specifically for mass airflow sensors. Nothing else and never should it be physically touched with anything. It is very delicate and damages easily.
