Check your ENG SENSOR fuse first, or measure the
harness voltages at the MAF. It wants +12V, a weak
+5V (output pullup) and GND. +12V comes off the
ENG SENSOR fused branch. You should get the specific
code, some of them are just bitching about reading
values and some indicate hard failures. You may not
need to replace anything, check it out.
