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.

Sintomi comuni

  • No shift
  • Speedometer dead
  • Trans limp

Cause tipiche

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

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori
