P0507 — Idle Speed Higher Than Expected

CAUTIONIs it safe to drive? The engine idles too high. Driveable but a high idle can mean a vacuum leak and makes the car creep — worth fixing.

What P0507 means

Actual idle RPM is above target. Most often unmetered air sneaking in (a vacuum leak) or a throttle body that needs cleaning/relearning.

Most likely causes (in order)

  1. Vacuum / intake leak
  2. Dirty throttle body or stuck throttle plate
  3. Idle control valve (older)
  4. Throttle relearn needed

Symptoms you might notice

What to check first

Smoke-test for vacuum leaks; clean the throttle body and relearn idle. On a speed-density engine a vacuum leak shows up as high idle rather than fuel-trim codes.
