The check engine light came on in my 99 Explorer . I looked under hood and noticed a vacuum hose partially inserted just past the MAF sensor . I inserted the hose fully and decided to clean the MAF . When I opened the air filter cover the air filter was crushed and pushed down in the housing not sealed around the perimeter . I reinstalled the filter and cleaned the sensor let dry and light went off .
I had a shop replace the alternator not too long ago and imagine they took the cover and hose off to get to the alternator and just laid the alternator(or something heavy) right on the air filter while working, crushed it and put the cover back on.
I am wondering if it was the MAF cleaning or the air filter being put back in place that cleared the check engine light ?
Should I consider replacing the MAF Sensor seeing that it is the original or leave it be for now ?
