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.

Veelvoorkomende symptomen

  • Intermittent ABS activation
  • ABS light
  • Speedometer fluctuation

Typische oorzaken

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

Welke scanner heb je nodig?

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

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert

Veelgestelde vragen

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.
