Did you read the link above? Your problem is electrical - not mechanical. (BTW - The only way your lid would be an issue is if a dead animal, etc. were in there and blocking airflow.) If you changed the MAF, then you have a cut or unplugged wire somewhere.
You should start measuring the voltage at the sensor plug and then work your way back through the circuit until you find the break.

Three wires:
Yellow - Sensor Signal
Black/White - Ground
Pink - Ignition Feed
With the ignition on but the engine off, you should see 5V between the Yellow and Black/White wire.
The factory manual has a very long procedure for testing the circuit, which involves testing the PCM and electrical frequency from the sensor, etc.
The manual also says that the code can be set by:
- Broken wires
- Engine vacuum leaks
- PCV leaks
- An incorrect PCV valve
- Missing engine oil fill cap
- Unseated engine oil dipstick
Yellow - Sensor Signal
Black/White - Ground
Pink - Ignition Feed
