P2767 Input/Turbine Shaft Speed Sensor B Circuit No Signal

P2767 reports that pulses from sensor B are missing. Ford's DPS6 dual-clutch box of 2012 checks input shaft 2 for lack of signal under this code, alongside P2765 for circuit faults and P2766 for erratic readings. Mitsubishi's 2022 CVT, whose sensor B watches the secondary pulley, looks for a sudden collapse: a speed of at least 1,000 rpm that reads zero only 10 ms later, held for 0.5 s – a pattern typical of a wire or plug letting go, rather than a slow sensor death. It is a two-trip code with MIL there; the fail-safe gives slow starts and acceleration, no lock-up and no manual mode. Check connector and harness first, then the sensor; where B sits inside a sealed unit, the repair may involve the whole assembly.

Likely causes

Connector or terminal letting go, open signal wire
Sensor B failed with no output
TCM sensor input defective

Symptoms

  • Warning lamp and transmission fail-safe
  • Slow start-off and weak acceleration
  • Manual shift mode not available
