What P0915 means
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.
P0915 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0915
- Check engine or transmission warning light on
- Gearbox drops to neutral while driving
- Gears refused or engaged only after a delay
Common causes of P0915
- Most 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
- Less likelyHigh resistance at connector pins distorting the signal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0915 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 15 | The exact fault in that area. |
What to do next
- Note P0915 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0915
What does P0915 mean?
P0915 means "Gear Shift Position Circuit A Range/Performance". Plausibility fault of the gear shift position signal on circuit A in an automated manual gearbox. It is a generic code, so it means the same on every make.
Is it safe to drive with P0915?
Drive gently and only to a workshop. With P0915 the car can go into limp mode (reduced power) to protect itself.
Will P0915 fail an emissions test?
Yes, it can. P0915 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0915 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0915 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
