Left Front Wheel Speed Sensor Circuit (Range/Performance)

Understand C0031, common causes, and the right TOPDON scanner to diagnose it.

LF wheel speed signal erratic or out of range — similar root causes to C0035.

Veelvoorkomende symptomen

  • ABS light
  • Pulsating pedal abnormal

Typische oorzaken

  • Sensor air gap
  • Tone ring crack
  • Contamination on sensor tip

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
