Pressure Control Solenoid Performance or Stuck Off

Understand P0746, common causes, and the right TOPDON scanner to diagnose it.

Pressure control solenoid not achieving commanded pressure.

Sintomi comuni

  • No movement
  • Weak shifts
  • Trans slip

Cause tipiche

  • Stuck solenoid
  • Internal leak
  • Low ATF pump output

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
