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.

Sintomi comuni

  • Intermittent ABS activation
  • ABS light
  • Speedometer fluctuation

Cause tipiche

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

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori

Domande frequenti

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.
