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.

Sintomi comuni

  • No shift
  • Limp mode
  • Stalling when shifting

Cause tipiche

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

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
