Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 1)

Understand P2472, common causes, and the right TOPDON scanner to diagnose it.

Primary EGT sensor circuit low.

Sintomi comuni

  • Regen inop
  • False overheat or underheat readings

Cause tipiche

  • Short in EGT harness
  • Failed probe
  • Heat damage at turbo area connector

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
