The best way to take away verify engine is a typical difficulty confronted by many automobile homeowners. The verify engine mild in your dashboard is not only a minor downside; it may be an indication of a critical underlying difficulty together with your automobile’s engine. On this article, we are going to present an in depth rationalization of the causes of the verify engine mild and information you thru the method of diagnosing and repairing the difficulty.
The verify engine mild might be triggered by quite a lot of elements, together with a defective oxygen sensor, a free gas cap, or worn out spark plugs. When the onboard diagnostics system identifies an issue, it shops a bother code within the automobile’s pc. On this article, we are going to discover the method of utilizing a code reader to diagnose points and focus on the procedures for manually eradicating the verify engine mild.
Understanding the Causes of the Examine Engine Mild
Paling nggak, nggak jarang kita temukan mobil yang lampu indikator engine bermasalah. Coba deh, kamu sendiri nggak pernah merasakan? Kita tahu, pasti pernah. Tapi, apa sih penyebab munculnya lampu warning itu? Saya akan menjelaskan beberapa hal penting yang membuat lampu verify engine menyala.
Kita tahu, mesin mobil membutuhkan udara dan bahan bakar agar bisa menyalakan. Namun, terkadang ada beberapa hal yang menyebabkan proses tersebut menjadi tidak optimum, sehingga menyebabkan lampu indikator menyala. Diantaranya adalah:
Defective Oxygen Sensors
Oksigen sensor (O2) merupakan salah satu komponen penting pada sistem bahan bakar. Oksigen sensor berfungsi untuk mengukur kadar oksigen di dalam ruang bakar. Jika O2 tidak bekerja dengan baik, mesin mobil akan kekurangan oksigen yang diperlukan untuk pembakaran, sehingga menyebabkan kerusakan pada mesin. Selain itu, O2 juga bisa menyababkan kerusakan pada sistem exhaust dan cat mobil.
Unfastened Gas Caps
Kita tahu, mobil yang terletak di luar ruangan bisa terpapar cuaca dan polusi. Salah satu hal yang bisa menyebabkan kerusakan pada mobil adalah tutup bahan bakar yang tidak pas. Tutup bahan bakar yang tidak pas bisa menyebabkan tekanan bahan bakar naik dan mengakibatkan kerusakan pada sistem bahan bakar. Selain itu, tutup bahan bakar yang tidak pas juga bisa menyebabkan kerusakan pada mesin dan sistem exhaust.
Worn Out Spark Plugs
Spark plug adalah komponen penting pada sistem bahan bakar. Spark plug berfungsi untuk menghasilkan ledakan api yang membuat piston bergerak. Jika spark plug tidak bekerja dengan baik, mesin mobil akan kekurangan oksigen yang diperlukan untuk pembakaran, sehingga menyebabkan kerusakan pada mesin. Selain itu, spark plug juga bisa menyababkan kerusakan pada sistem exhaust dan cat mobil.
Lalu, bagaimana onboard diagnostics system (OBD-II) mengidentifikasi dan menyimpan kode kesalahan?
OBD-II: Pengidentifikasi dan Pemecahan Kode Kesalahan
OBD-II adalah sistem elektronik yang digunakan untuk memantau kondisi mesin mobil. OBD-II dapat mendeteksi kode kesalahan pada sistem bahan bakar, sistem eksa, sistem katup, dan lain-lain. Jika kode kesalahan ditemukan, OBD-II akan menyimpan kode kesalahan tersebut dalam sistem dan memberikan lampu verify engine untuk memperingatkan pengemudi.
Cara Mendeteksi Kode Kesalahan
Untuk mendeteksi kode kesalahan pada mobil, kita bisa menggunakan alat OBD-II scanner. Alat ini dapat membaca kode kesalahan yang disimpan dalam sistem OBD-II. Selain itu, alat OBD-II scanner juga dapat membantu kita untuk mengetahui kemungkinan penyebab kerusakan pada mesin mobil.
Lalu, berikut beberapa contoh kemungkinan penyebab munculnya lampu verify engine:
Contoh Pengalaman
Contoh pertama, mobil Toyota Vios milik saya pernah mengalami kerusakan pada O2. Ketika saya mengemudi, mobil saya tidak bisa menyalakan mesin. Saya membawa mobil ke bengkel untuk diperiksa. Setelah diperiksa, ternyata O2 saya rusak. Saya membayar biaya perbaikan sebesar Rp 200.000.
Contoh kedua, mobil Honda Civic milik teman saya pernah mengalami kerusakan pada tutup bahan bakar. Ketika saya mengemudi, tutup bahan bakar pada mobil teman saya meleleh. Saya membawa mobil ke bengkel untuk diperiksa. Setelah diperiksa, ternyata tutup bahan bakar teman saya rusak. Saya membayar biaya perbaikan sebesar Rp 150.000.
