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.

Vanliga symptom

  • Intermittent ABS activation
  • ABS light
  • Speedometer fluctuation

Typiska orsaker

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

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer

Vanliga frågor

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.
