P2282
Air Leak Between Throttle Body and Intake Valves
Fuel & air metering (intake)
Generic OBD-II
Medium
What it means
P2282 means the ECM has detected unmetered air entering the engine between the throttle body and the intake valves — air that bypasses the throttle and airflow sensor. It is a vacuum or intake-leak problem, typically a cracked gasket, torn intake boot, or a bad PCV or vacuum hose. The result is a lean mixture, so the engine idles rough and may stall until the leak is sealed.
Medium
Can I keep driving? Usually yes, but expect a rough or high idle and possible stalling at stops; large leaks can make the car hard to keep running until repaired.
Common symptoms
What you'll notice
- Rough, unstable, or unexpectedly high idle
- Check-engine light on, often with lean codes
- Hesitation or a lean stumble on light acceleration
- Possible stalling at idle or when coming to a stop
Common causes
Most likely first
- Cracked or leaking intake manifold or throttle-body gasketLikely
- Torn or loose intake air boot/hose after the throttle bodyCommon
- Faulty or stuck-open PCV valve or a disconnected PCV/vacuum hoseCommon
- Leaking brake booster hose or other vacuum lineLess often
- Leaking fuel injector seals or intake manifold cracksLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check for accompanying lean codes to confirm unmetered air.
- Visually inspect the intake boot, manifold gasket, and vacuum hoses for cracks or loose clamps.
- Perform a smoke test of the intake to pinpoint the leak.
- Replace the failed gasket, hose, or PCV component and re-clamp connections.
- Clear the code and confirm idle stabilizes and fuel trims return to normal.
FAQ
Quick answers
Is it safe to drive with P2282?+
Short trips are usually fine, but a lean condition can cause rough idle, stalling, and over time contribute to misfires. Repair it promptly.
Can I just clear P2282?+
It will return quickly because the extra air the engine is drawing in is still there — the leak has to be sealed.
