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.

Vanliga symptom

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

Typiska orsaker

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

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 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.
