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.

Vanliga symptom

  • No movement
  • Weak shifts
  • Trans slip

Typiska orsaker

  • Stuck solenoid
  • Internal leak
  • Low ATF pump output

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
