Crankshaft Position Sensor A Circuit

Understand P0335, common causes, and the right FOXWELL scanner to diagnose it.

The ECU lost or received invalid crankshaft position signal. Without it, the engine may not start or may stall.

Síntomas habituales

  • Intermittent cut-out while driving

Causas típicas

  • Failed crank sensor
  • Damaged reluctor wheel
  • Wiring or connector fault
  • Sensor air gap out of spec

¿Qué escáner necesita?

Enhanced OBD2 scanner (live data graphs, freeze frame, battery voltage test)

Use datos en vivo y freeze frame antes de cambiar piezas. Códigos ABS, SRS y U suelen requerir un escáner de todos los sistemas.

Consejos de diagnóstico

  • Registre el freeze frame cuando se active el código
  • Borre el código solo tras corregir la causa
  • Revise códigos pendientes relacionados
  • Verifique que la batería esté por encima de 12,4 V antes de sospechar sensores

Preguntas frecuentes

Can I diagnose P0335 with a basic code reader?
P0335 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Is it safe to drive with P0335?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
