What P0914 means
Circuit A of the gear shift position sensor reports how far the shift mechanism of an automated manual gearbox has moved in the shift direction, i.e. whether a gear is engaged, in neutral or in between. This generic circuit code sets on an electrical fault on that signal that does not match the more specific variants. No manufacturer documents the code publicly. An Aisin AI patent pairs such a shift stroke sensor with a select stroke sensor, and a Nissan/Aichi patent places the shift position sensor as a magnet and field detector on the piston of a hydraulic shift actuator. CARB requires circuit checks on such inputs. P0915 to P0919 are the siblings, P091A and P095A the same signal on circuits B and C. Without it the module cannot confirm the engaged gear and usually blocks shifting.
P0914 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 P0914
- Check engine or transmission warning light on
- Gearbox stops shifting or stays in neutral
- Engine may not start because neutral cannot be confirmed
Common causes of P0914
- Most likelyLoose or corroded connector at the shift sensor or actuator unit
- PossibleDamaged sensor wiring near the gearbox
- PossibleFaulty gear shift position sensor
- Less likelyFaulty sensor input or reference supply in the transmission control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0914 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. |
| 14 | The exact fault in that area. |
What to do next
- Note P0914 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 P0914
What does P0914 mean?
P0914 means "Gear Shift Position Circuit A". Circuit A of the gear shift position sensor reports how far the shift mechanism of an automated manual gearbox has moved in the shift direction, i.e. It is a generic code, so it means the same on every make.
Is it safe to drive with P0914?
Drive gently and only to a workshop. With P0914 the car can go into limp mode (reduced power) to protect itself.
Will P0914 fail an emissions test?
Yes, it can. P0914 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 P0914 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0914 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
