3B poor running - dead MAF!!!

[Mihnea Cotet]

Gang,


So this afternoon I proceded to test the MAF as per the factory! I got 0 V
between connections 1 and 3 with the ignition switch in "on" position
(should be 2.5V) idling (should be same) and revved up (should go up to
3-5V). Also, resistance between terminals 1 and 2 goes between 4 and 50
Ohms when it's supposed to be 0 Ohms or a direct connection.

So guess what's the next surprise? It's damn dead!

Oh well, I'll just replace it with a used one as well as a brand new O2
sensor...
