P2280

Air Flow Restriction/Air Leak Between Air Filter and MAF Bank 1

Q: Is it safe to drive with P2280?

Usually yes for short trips, but unmetered air upsets the fuel mixture, so the engine can run rough or lean. Fix it promptly to avoid follow-on lean or misfire codes.

Q: Can I just clear P2280?

It returns until the air leak or restriction between the filter and MAF is repaired. Find and fix the leak first.

Fuel & air metering Generic OBD-II Medium

What it means

P2280 means the engine is drawing air that bypasses the mass air flow (MAF) sensor, or airflow is restricted, somewhere between the air filter and the MAF. Because the MAF no longer measures all the incoming air, the fuel mixture is off — the engine can idle rough, hesitate, or lose power. It's almost always a loose or cracked intake duct, a bad clamp, or a clogged filter.

Medium

Can I keep driving? Usually yes, but the engine may run rough or lack power; fix it soon so the wrong air readings don't cause other problems.

How to diagnose & fix

Work through it in order

Scan and confirm P2280, then inspect the ducting between the air filter box and the MAF sensor.
Check every clamp and joint for looseness, cracks, or splits; reseat the air filter.
Smoke-test the intake to pinpoint an unmetered-air leak.
Replace a clogged air filter.
Verify the MAF sensor reads correctly once leaks are fixed, then clear and re-test.
