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.

Vanliga symptom

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

Typiska orsaker

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

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer

Vanliga frågor

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.
