Wheel Speed Sensor Frequency Error

Understand C0245, common causes, and the right TOPDON scanner to diagnose it.

Wheel speed sensor signal frequency out of expected range — often tone ring or sensor air gap.

Typowe objawy

  • Intermittent ABS activation
  • ABS light
  • Speedometer fluctuation

Typowe przyczyny

  • Incorrect sensor gap
  • Damaged exciter ring
  • Contaminated sensor tip
  • Wrong sensor installed

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 C0245 mean?
C0245 indicates wheel speed sensor frequency error. Wheel speed sensor signal frequency out of expected range — often tone ring or sensor air gap.
Can I diagnose C0245 with a basic code reader?
C0245 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 C0245?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with C0245?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
