OBD2 Code Simulator carian kod OBD2

Gunakan OBD2 Code Simulator sebagai carian kod sebelum berlatih. Baca maksud kod, punca biasa, simptom, semakan pertama, dan sama ada kereta boleh dipandu.

P0300

Maksud

Misfire rawak/beberapa silinder dikesan

Tinggi

Punca biasa

Busi aus atau koil lemah
Kebocoran vakum atau campuran terlalu miskin
Tekanan bahan bakar rendah, injektor, atau kompresi

Simptom

Idle kasar atau bergetar
Tersendat saat beban
Check Engine berkedip atau menyala

Semak dahulu

Jika lampu berkedip, kurangi beban dan berhenti saat aman. Lalu baca freeze frame, misfire counter, fuel trim, busi/koil, dan kebocoran vakum.

Boleh dipandu?

Hindari berkendara jika lampu berkedip atau getaran kuat. Jika ringan dan lampu menyala stabil, berkendara hati-hati ke tempat diagnosis.

P0301

Maksud

Misfire silinder 1

Tinggi

Punca biasa

Busi atau koil silinder 1
Injektor silinder 1
Masalah kompresi atau vakum pada satu silinder

Simptom

Bergetar saat idle
Tenaga turun
Bau bahan bakar atau lampu berkedip saat beban

Semak dahulu

Periksa busi dan koil silinder 1, lalu lakukan coil swap atau tes balance injektor sebelum mengganti komponen.

Boleh dipandu?

Jangan lanjut jika bergetar keras atau lampu berkedip. Untuk kasus ringan, cukup jarak pendek ke bengkel.

P0171

Maksud

Sistem terlalu lean, bank 1

Sederhana

Punca biasa

Kebocoran vakum setelah MAF
MAF kotor atau membaca terlalu rendah
Tekanan bahan bakar rendah atau aliran terbatas

Simptom

Start lama atau idle kasar
Kurang tenaga di tanjakan
Fuel trim positif dan mungkin ada kode misfire

Semak dahulu

Bandingkan STFT/LTFT, periksa kebocoran intake, lalu tes data MAF dan tekanan bahan bakar saat beban.

Boleh dipandu?

Biasanya bisa jarak pendek jika ringan, tetapi hindari beban berat dan perbaiki segera.

P0420

Maksud

Kecekapan katalis di bawah ambang, bank 1

Sederhana

Punca biasa

Catalytic converter aus
Kebocoran knalpot sebelum/dekat katalis
Sensor O2 atau misfire/rich/oil burning yang belum selesai

Simptom

Sering tidak ada gejala
Gagal uji emisi
Bau sulfur atau tenaga turun jika parah

Semak dahulu

Pastikan tidak ada misfire atau kode fuel trim aktif, singkirkan kebocoran knalpot, lalu bandingkan sensor O2 upstream dan downstream.

Boleh dipandu?

Biasanya bisa ke tempat diagnosis jika tidak ada lampu berkedip, panas berlebih, atau tenaga hilang besar.

P0113

Maksud

Input tinggi litar sensor suhu udara masuk

Rendah

Punca biasa

Sensor IAT tercabut atau konektor longgar
Kabel sinyal atau ground terbuka
Sensor IAT rusak

Simptom

Bacaan suhu intake tidak masuk akal
Start dingin atau fueling terasa salah
Boros bahan bakar

Semak dahulu

Bandingkan IAT dengan suhu sekitar, periksa konektor dan kabel, lalu tes tegangan sinyal.

Boleh dipandu?

Sering bisa jarak pendek, tetapi perbaiki segera karena PCM dapat salah menghitung kepadatan udara.

P0122

Maksud

Input rendah litar sensor posisi throttle

Sederhana

Punca biasa

Konektor throttle/TPS korosi atau longgar
Short to ground atau referensi 5 V terbuka
TPS atau throttle body rusak

Simptom

Respons throttle terbatas
Akselerasi seperti limp mode
Mati mesin atau idle buruk

Semak dahulu

Cek live data sudut throttle, periksa pin konektor, lalu tes referensi 5 V, ground, dan sinyal.

Boleh dipandu?

Hanya jika respons throttle dapat diprediksi. Limp mode, mati mesin, atau akselerasi tidak aman perlu diperbaiki dulu.

P0335

Maksud

Kerosakan litar sensor posisi crankshaft

Tinggi

Punca biasa

Sensor crankshaft rusak
Kabel atau konektor sensor rusak
Masalah sinyal timing atau reluctor wheel

Simptom

Crank tetapi tidak start
RPM nol saat cranking
Stall intermittent atau tidak ada perintah spark

Semak dahulu

Pantau RPM saat cranking, pastikan tegangan aki dan tekanan bahan bakar, lalu tes sinyal sensor crank dan kabel.

Boleh dipandu?

Jika mesin stall atau tidak start, jangan dikendarai. P0335 intermittent bisa membuat mobil mogok.

Laluan diagnostik OBD2 Code Simulator

Kod masalah menunjukkan sistem yang gagal pemantauan. Langkah seterusnya perlu berasaskan bukti.

Baca kod

Catat stored, pending, dan permanent codes sebelum memadamkan apa-apa.

Semak freeze frame

Gunakan RPM, beban, kelajuan, suhu coolant, dan fuel trim untuk melihat keadaan semasa masalah berlaku.

Bandingkan live data

Pantau fuel trim, O2, RPM, voltan bateri, tekanan, dan isyarat sensor.

Periksa komponen

Uji sistem paling mungkin dengan pemeriksaan visual, penyambung, voltan, tekanan, atau swap test.

Buat kesimpulan

Pilih pembaikan hanya selepas kod, simptom, freeze frame, live data, dan pemeriksaan sepadan.
