Engine Speed Input Circuit

Understand P0725, common causes, and the right TOPDON scanner to diagnose it.

TCM not receiving reliable engine speed signal from crank/cam or CAN.

Vanliga symptom

  • No shift
  • Limp mode
  • Stalling when shifting

Typiska orsaker

  • Crank sensor fault
  • CAN communication issue
  • TCM software
  • Wiring between ECM and TCM

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
