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.

Veelvoorkomende symptomen

  • No shift
  • Speedometer dead
  • Trans limp

Typische oorzaken

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

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
