P0507 P0xxx · パワートレーン (P) 重大度中
Idle Control System RPM Higher Than Expected
The engine idles above the target speed and the ECU cannot bring it down. Either extra air is getting in, or the throttle is not closing as commanded.
重大度の目安： 中 — 走行性または排出ガスに影響。今週中に点検を予約してください

点検・修理の手順
費用が安く侵襲の小さい項目から — これらのコードの大半は部品の問題ではありません。
- ✓ Check for unmetered air with a smoke test — this is the fastest route.
- ✓ Inspect and clean the throttle body bore and plate edges.
- ✓ Watch the commanded vs actual throttle position in live data.
- ✓ Confirm the throttle learns correctly after cleaning (relearn procedure).
修理の選択肢
- Repair the vacuum leak
- Clean the throttle body and perform the relearn
- Replace the idle control valve
P0507 — よくあるご質問
Why did it start after I cleaned the throttle? +
Cleaning removes the carbon the ECU had adapted to. Run the throttle relearn so the plate position matches the new airflow.
Is a high idle harmful? +
It wastes fuel and makes gear engagement harsh. Over time it also wears the driveline.
