could be:
– Open circuit
– Short circuit to ground
– Mass air flow sensor

The diagnostic flow chart suggests checking both sides of the MAF to DME wiring before it finally leads you to the change MAF box where it also suggests an air filter replacement.

Easy way is a MAF swap and drive for an hour with CEL turned off. No CEL after a long drive, problem solved. But that assumes you have the MAF part to throw at the problem and that gets expensive.
