P2795Gear Shift Direction Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2795 is the upper-limit fault of the shift direction signal: the value seen by the controller is higher than any real sensor position could produce. That pattern fits a signal wire touching a battery or 5 volt feed, a lost sensor ground, or an interrupted signal line on an input that is pulled up inside the module. A sensor whose output stage has failed may also report a constant high level. No manufacturer publishes set conditions for P2795; the check belongs to the range tests in CARB 13 CCR 1968.2. P2794 is the low-side twin and P2793 the plain circuit fault. When diagnosing, compare the ground drop at the sensor with the controller ground before suspecting the actuator. Until the fault is cleared the gearbox usually refuses to change gear and lights its warning lamp.

- PossibleShift direction sensor stuck at a high output
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
