Output Speed Sensor Circuit

Understand P0720, common causes, and the right TOPDON scanner to diagnose it.

Output shaft speed sensor fault. Often causes erratic shifting and may store P0700 as parent code.

Veelvoorkomende symptomen

  • Flare on shifts
  • ABS light (shared sensor on some cars)
  • Limp mode

Typische oorzaken

  • Failed OSS sensor
  • Wiring damage
  • Metal debris 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

Veelgestelde vragen

What does P0720 mean?
P0720 indicates output speed sensor circuit. Output shaft speed sensor fault. Often causes erratic shifting and may store P0700 as parent code.
Can I diagnose P0720 with a basic code reader?
P0720 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 P0720?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P0720?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
