Input/Turbine Speed Sensor Circuit

Understand P0715, common causes, and the right TOPDON scanner to diagnose it.

Transmission input speed sensor signal missing or invalid. TCM uses it for shift timing and torque converter lockup.

Veelvoorkomende symptomen

  • Harsh shifts
  • No shift
  • Speedometer issues on some models

Typische oorzaken

  • Failed input speed sensor
  • Wiring fault
  • Internal transmission damage
  • Contaminated fluid

Welke scanner heb je nodig?

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

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert

Veelgestelde vragen

What does P0715 mean?
P0715 indicates input/turbine speed sensor circuit. Transmission input speed sensor signal missing or invalid. TCM uses it for shift timing and torque converter lockup.
Can I diagnose P0715 with a basic code reader?
P0715 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 P0715?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P0715?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
