What P2282 means
P2282 means air enters the intake behind the throttle, so it reaches the cylinders without passing the throttle. Ford uses it as its PCV monitor on turbo engines with speed density: airflow worked out from manifold pressure is compared with airflow through the throttle, and a calculated leak of 1 lb/min or more for at least 5 s, with the throttle at 4 degrees or less, sets the code (2012, 2020-2023 and 2024 summaries). Ford designed the PCV inlet tube so that pulling it off leaves a large, detectable opening. Ford bulletins blame a stuck-open brake vacuum valve or tube on the 2.0 EcoBoost in the 2019-2020 Edge and Nautilus (TSB 20-2151), ice in the manifold of the 2020-2021 Escape hybrid (SSM 49654) and PCM software on the 2023 Maverick hybrid (TSB 23-2193). Land Rover found a detached brake vacuum pipe (LTB01186).
P2282 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P2282
- High or unstable idle speed
- MIL on, sometimes with a hissing noise from the engine bay
- Harder brake pedal if the brake vacuum line is affected
Common causes of P2282
- Most likelyBrake booster vacuum pipe detached or its check valve stuck open
- Most likelyCrankcase ventilation hose disconnected or cracked
- PossibleLeaking intake manifold gasket, throttle body seal or vacuum hose
- Less likelyIced manifold pressure sensor or software miscalculating the leak
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2282 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). |
| 82 | The exact fault in that area. |
What to do next
- Note P2282 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 P2282
What does P2282 mean?
P2282 means "Air Leak Between Throttle Body and Intake Valves". P2282 means air enters the intake behind the throttle, so it reaches the cylinders without passing the throttle. It is a generic code, so it means the same on every make.
Is it safe to drive with P2282?
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 P2282 fail an emissions test?
Yes, it can. P2282 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 P2282 to fix?
Difficulty: medium. A typical repair takes 0.3 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2282 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.
