Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

Exhaust Gas Temperature Sensor Circuit Performance (Bank 1 Sensor 3)

Understand P247B, common causes, and the right TOPDON scanner to diagnose it.

Third EGT sensor (often post-DPF) performance fault.

Typowe objawy

  • Regen monitoring fault
  • SCR efficiency codes

Typowe przyczyny

  • Failed post-DPF EGT
  • Sensor tip soot insulated
  • Wiring fault

Jakiego skanera potrzebujesz?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Użyj danych na żywo i freeze frame przed wymianą części. Kody ABS, SRS i U zwykle wymagają skanera full-system.

Wskazówki diagnostyczne

  • Zapisz freeze frame, gdy pojawi się kod
  • Kasuj kod dopiero po usunięciu przyczyny
  • Sprawdź powiązane kody pending
  • Sprawdź, czy napięcie akumulatora jest powyżej 12,4 V przed podejrzeniem czujników

Często zadawane pytania

What does P247B mean?
P247B indicates exhaust gas temperature sensor circuit performance (bank 1 sensor 3). Third EGT sensor (often post-DPF) performance fault.
Can I diagnose P247B with a basic code reader?
P247B may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Which TOPDON scanner do I need for P247B?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P247B?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
