P0915Gear Shift Position Circuit A Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Plausibility fault of the gear shift position signal on circuit A in an automated manual gearbox. The voltage stays within its electrical limits, but the reading does not fit: the signal does not change while the shift actuator moves, or the engaged position does not match the learned gear positions. No manufacturer documents this code in freely citable material. A Nissan/Aichi patent points out that sensor brackets on shift forks can deform under vibration and spoil the reading, and an Aisin AI patent describes the fallback when a stroke sensor can no longer be trusted. CARB requires rationality checks on such inputs. P0914, P0916 and P0917 are the electrical faults, P0919 a shift movement that misses its target. Shifting becomes limited or stops.
- What you may notice
- Check engine or transmission warning light on
- Gearbox drops to neutral while driving
- Gears refused or engaged only after a delay
- Likely causes
- LikelyWorn or drifting shift position sensor, redundant tracks disagree
- PossibleBent sensor bracket or displaced magnet on the shift rod
- PossibleGear positions not relearned after actuator or TCM replacement
- RareHigh resistance at connector pins distorting the signal
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
