P2767Input/Turbine Shaft Speed Sensor B Circuit No Signal
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Warning lamp and transmission fail-safe
- Slow start-off and weak acceleration
- Manual shift mode not available
- Likely causes
- LikelyConnector or terminal letting go, open signal wire
- PossibleSensor B failed with no output
- RareTCM sensor input defective
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
