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.

Veelvoorkomende symptomen

  • Regen inop
  • False overheat or underheat readings

Typische oorzaken

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

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
