P0715 to P0718: input and turbine speed sensor
The sensor that measures how fast the automatic gearbox's input shaft, or the torque converter's turbine, is turning has a circuit fault, no signal or an implausible reading.
SeverityModerateUsually not urgent today, but it can get worse if left.
Can you keep driving?Drive gently, check it soonWhat does P0715 mean?
The gearbox computer compares the input speed with the output speed to know which gear is engaged, how fast a shift is happening and how much the torque converter is slipping. Without a valid input speed it cannot time shifts smoothly, so most gearboxes shift harshly or hold a fixed gear until the fault is fixed.
What causes P0715?
- A failed input speed sensor
- A damaged wire or a fluid-soaked connector at the gearbox
- Metal debris on the sensor tip from gearbox wear
- A damaged reluctor ring on the input shaft, less often
What to check first for P0715
- Read every transmission code; a speed sensor code with ratio codes points at the sensor first
- Inspect the sensor connector for fluid and corrosion
- Check the sensor tip for metal debris, and the fluid for metal
- Watch the input speed signal on a scan tool while driving gently
Can you drive with P0715?
Usually drivable to a workshop, gently. Expect harsh shifts or a fixed gear; avoid fast roads and heavy loads until it is repaired.
In states with an OBD-II emissions inspection, a car with the check engine light on fails the test until the fault is fixed.
