P0507 — Idle air control system RPM higher than expected
Idle is higher than commanded — vacuum leaks and dirty throttles show up here too, in the opposite direction from P0506.
What it means in plain English
P0507 is idle RPM higher than expected. A vacuum leak that lets in unmetered air, a stuck idle valve, or throttle issues can raise idle. Compare with P0506 (idle too low).
Common causes
- Vacuum leak
- Dirty or sticking throttle / idle control
- Incorrect idle adaptation after battery disconnect or cleaning
What you can safely check
- Listen for hissing; check obvious hose connections.
- Note if idle spiked after recent battery or throttle service.

FAQ
What should I do first with a P0507 code?
Photograph all codes, note symptoms and whether the light is flashing, avoid clearing data until a shop sees it, then use an independent shop with a clear diagnostic plan.
