P07F1Input/Turbine Shaft Speed Sensor C Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P07F1 is the general circuit code of a third input or turbine shaft speed sensor, after sensor A (P0715) and B (P2765); low and high for sensor C are P07C3 and P07C4. No production use could be found in GM tables from 2015 to 2025, Ford's summaries of 2012 and 2020–23, Mitsubishi's code index or manufacturer bulletins; such a sensor would make sense on transmissions with three input shafts or a hybrid input. The check would follow P0715: no plausible signal while driving or an open circuit. The module then uses a substitute value, keeps the converter clutch open and shifts more harshly; with emissions impact CARB requires the MIL.
- What you may notice
- Check engine lamp (expected)
- Harsh shifts, converter clutch stays open
- Limp mode possible
- Likely causes
- PossibleSensor wire or connector open
- PossibleSpeed sensor faulty
- RareControl module or software
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
