P0917Gear Shift Position Circuit A 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
- Set when the gear shift position signal on circuit A of an automated manual gearbox stays above its highest valid value for longer than a calibrated time. The signal line may be shorted to the sensor supply or to battery voltage, the sensor ground may be open, or the sensor itself may be faulty. No manufacturer documents this code publicly. The Aisin AI and Nissan/Aichi patents show the shift stroke or shift position sensor as the feedback that confirms an engaged gear; with a reading above the valid band the controller can no longer tell neutral from an engaged gear. CARB requires out-of-range checks on such inputs. P0916 is the opposite low fault, P091D and P095D are the high faults of circuits B and C, P0919 a shift movement that misses its target. Shifting is usually locked.
