Input/Turbine Speed Sensor Circuit Intermittent

Understand P0718, common causes, and the right TOPDON scanner to diagnose it.

Intermittent input speed sensor signal.

Häufige Symptome

  • Random trans limp
  • Flare shifts

Typische Ursachen

  • Intermittent sensor failure
  • Connector at trans pan
  • Internal harness fatigue

Welchen Scanner brauchen Sie?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Nutzen Sie Live-Daten und Freeze Frame, bevor Sie Teile tauschen. ABS-, SRS- und U-Codes erfordern meist einen Vollsystem-Scanner.

Diagnose-Tipps

  • Freeze Frame erfassen, wenn der Code erstmals gesetzt wird
  • Code erst nach Behebung der Ursache löschen
  • Auf verwandte pending codes prüfen
  • Batteriespannung über 12,4 V prüfen, bevor Sie Sensoren verdächtigen

Häufig gestellte Fragen

What does P0718 mean?
P0718 indicates input/turbine speed sensor circuit intermittent. Intermittent input speed sensor signal.
Can I diagnose P0718 with a basic code reader?
P0718 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Which TOPDON scanner do I need for P0718?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P0718?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
