Transmission Range Sensor Circuit Malfunction (PRNDL Input)

Understand P0705, common causes, and the right TOPDON scanner to diagnose it.

Gear selector position sensor circuit fault — TCM does not know selected range.

Sintomi comuni

  • Wrong gear indicated
  • No crank in park/neutral
  • Trans limp

Cause tipiche

  • Failed range sensor on side of trans
  • Shift cable out of adjustment
  • Wiring in console harness

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
