P07F1 Input/Turbine Shaft Speed Sensor C Circuit

EmissionsRelevant
Drive cycleNot required

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.

Likely causes

Sensor wire or connector open
Speed sensor faulty
Control module or software

Symptoms

  • Check engine lamp (expected)
  • Harsh shifts, converter clutch stays open
  • Limp mode possible
