Structured DTC reference

What P0507 means

The idle speed is higher than it should be

A trouble code identifies the circuit or monitored condition that failed its test. It does not, by itself, identify the failed part or prove the same cause on every vehicle.

Cause categories to discriminate

  • Dirty throttle body

These are structured diagnostic hypotheses, not a parts-replacement list. Vehicle context, symptoms, operating conditions, and test results determine which remain supported.

Severity and drivability

The code alone is not enough to assign one universal severity or “safe to drive” answer. Stop driving for loss of braking or steering, severe overheating, oil-pressure loss, a fuel leak or fire risk, or any rapidly worsening safety symptom.

  • Check-engine light

Likely causes

  • Vacuum leak
  • Dirty throttle body or IAC issue

Diagnosis steps

  1. Inspect for vacuum leaks
  2. Clean the throttle body
  3. Recheck idle and relearn if needed
