System
Powertrain (Transmission)
Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

Output Speed Sensor Circuit No Signal

Understand P0722, common causes, and the right TOPDON scanner to diagnose it.

No output speed sensor signal to TCM.

Typowe objawy

  • No shift
  • Speedometer dead
  • Trans limp

Typowe przyczyny

  • Failed OSS sensor
  • Open harness at trans
  • TCM not receiving VSS data

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
