Rear Wheel Speed Sensor Correlation

Understand C0070, common causes, and the right TOPDON scanner to diagnose it.

ABS module detected mismatched rear wheel speed readings — one rear sensor may read differently from the other.

Veelvoorkomende symptomen

  • ABS light
  • Traction control activation on straight road
  • False stability intervention

Typische oorzaken

  • One rear sensor failing
  • Different tire sizes on rear axle
  • Tone ring damage one side
  • Rear bearing play

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 C0070 mean?
C0070 indicates rear wheel speed sensor correlation. ABS module detected mismatched rear wheel speed readings — one rear sensor may read differently from the other.
Can I diagnose C0070 with a basic code reader?
C0070 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 C0070?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with C0070?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
