MotorBitP0507: Idle Air Control System RPM Higher Than Expected
Idle is higher than the PCM wants. Vacuum leaks and dirty throttle bodies are common.
Educational OBD2 information. Confirm on your vehicle with a scan tool. MotorBit can read this code, freeze frame, and live data over an ELM327 adapter.
What P0507 means
Idle speed exceeded the target by enough to set a monitor.
Why the check engine light comes on
Uncontrolled idle affects emissions and stall/safety behavior.
Common causes
- Vacuum leak

How MotorBit helps
Open MotorBit, connect your ELM327, and read P0507 with freeze frame (RPM, load, temperature, speed at the moment the fault set). Then watch live PIDs and fuel trims instead of replacing parts by guesswork. When the repair is verified, clear the code and re-check monitors.

FAQ
Is P0507 serious?
Severity is listed as low on this page. Misfire, crank/cam, and communication codes deserve faster attention than a tiny EVAP leak.
Will disconnecting the battery clear P0507?
It may hide the lamp temporarily, but the fault usually returns and you lose freeze-frame evidence. Scan first, then clear after the repair.
Can MotorBit clear P0507?
Yes, after you understand the cause. Clearing without a repair is how the light comes back on the next drive cycle.
