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.

Typowe objawy

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

Typowe przyczyny

  • Failed OSS sensor
  • Wiring damage
  • Metal debris on sensor tip

Jakiego skanera potrzebujesz?

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

Użyj danych na żywo i freeze frame przed wymianą części. Kody ABS, SRS i U zwykle wymagają skanera full-system.

Wskazówki diagnostyczne

  • Zapisz freeze frame, gdy pojawi się kod
  • Kasuj kod dopiero po usunięciu przyczyny
  • Sprawdź powiązane kody pending
  • Sprawdź, czy napięcie akumulatora jest powyżej 12,4 V przed podejrzeniem czujników

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.
