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.

Vanliga symptom

  • No shift
  • Speedometer dead
  • Trans limp

Typiska orsaker

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

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer
