Reductant System Performance

Understand P2062, common causes, and the right TOPDON scanner to diagnose it.

Overall reductant/DEF system not meeting performance targets.

Veelvoorkomende symptomen

  • Derate
  • Multiple P2B/P20 codes
  • Check engine light

Typische oorzaken

  • Combined pump/injector/catalyst faults
  • Extended driving with empty DEF
  • Bad DEF quality

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
