What P2280 means
P2280 is the bank 1 code for restricted airflow or an air leak between the air filter and the MAF sensor. A blocked filter lowers the pressure ahead of the sensor and limits the air the engine can take in. A leak in this section matters less for fuel metering, since the air still passes the MAF, but it lets unfiltered air and dust reach the engine. FCA's heavy-duty Ram trucks with the 6.7 L Cummins diesel are the documented users: with 2016 software, bulletin 18-027-16 made P2280 wait for two trips instead of one before the MIL, and FCA tech tip 9003821 (2017) notes MIL events where oil-soaked intake filters were being replaced. FCA's older wording names the code without a bank. P227F is the bank 2 counterpart, P2281 covers the stretch from the MAF to the throttle.
P2280 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.2 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2280
- MIL on
- Less power and slower boost build-up under load
- More smoke from diesel engines when accelerating
Common causes of P2280
- Most likelyAir filter clogged or soaked with oil
- PossibleSnow, ice or debris in the air inlet, or a collapsed intake duct
- PossibleCracked duct or loose clamp between filter box and MAF
- Less likelyEarly software that flags the condition too readily
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2280 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 80 | The exact fault in that area. |
What to do next
- Note P2280 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2280
What does P2280 mean?
P2280 means "Air Flow Restriction/Air Leak Between Air Filter and MAF (Bank 1)". P2280 is the bank 1 code for restricted airflow or an air leak between the air filter and the MAF sensor. It is a generic code, so it means the same on every make.
Is it safe to drive with P2280?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2280 fail an emissions test?
Yes, it can. P2280 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2280 to fix?
Difficulty: easy. A typical repair takes 0.2 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2280 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
