Drove without MAF for 3-4 days

[maor]

This is strange, I got distracted when putting my airbox back on and forgot to plug the MAF and closed the bonnet.

For 3-4 days I was driving around and noticed absolutely nothing wrong with my car. It wasn't until I checked the coolant level that I spotted the MAF was unplugged 3-4 days later, like 75 miles I must have put on the car.

No CEL light, no warning nothing. I did plug durametric in the day before and it had the MAF fault but I thought nothing of it and assumed it was an old code from a month earlier when I was doing some diagnostics.

Why did I get no EML light or anything? Is my MAF failing ?

What was the code?

[maor]

Can't remember, I think it was low voltage to maf or soemthing like that. I can get it back by unplugging it though

The code would have been P0102 Mass Air Flow Sensor - Below Lower Limit (open circuit)

As Loren specified in another topic : if you don't feel the difference between WITH or WITHOUT a MAF (above 4000 rpm), then it's failing.

In my experience, a failing MAF will cause hesitation above 4000 rpm.
