What P095B means
Plausibility fault of the shift position signal on circuit C of an automated manual gearbox. The voltage is electrically acceptable, but the value does not fit: it contradicts the other position channels, stays put while the shift actuator moves, or misses the learned gear positions. No manufacturer documents this code publicly. A Nissan/Aichi patent points out that sensor mountings on shift parts can give way under vibration and distort the reading; an Aisin AI patent explains how control carries on when a stroke sensor can no longer be trusted. CARB requires rationality checks on such inputs. P095A, P095C and P095D are the electrical faults of circuit C, P0915 and P091B the same check on A and B.
P095B at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P095B
- Transmission warning light on
- Harsh or aborted gear changes
- Fallback mode with fewer available gears
Common causes of P095B
- Most likelyWorn or drifting shift position sensor C disagreeing with the other channels
- PossibleBent sensor bracket or displaced magnet on the shift rail
- PossibleGear positions not relearned after actuator or module replacement
- Less likelyIncreased contact resistance in the sensor circuit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P095B 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. |
| 5B | The exact fault in that area. |
What to do next
- Note P095B 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 P095B
What does P095B mean?
P095B means "Gear Shift Position Circuit C Range/Performance". Plausibility fault of the shift position signal on circuit C of an automated manual gearbox. It is a generic code, so it means the same on every make.
Is it safe to drive with P095B?
Drive gently and only to a workshop. With P095B the car can go into limp mode (reduced power) to protect itself.
Will P095B fail an emissions test?
Yes, it can. P095B 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 P095B to fix?
Difficulty: hard. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P095B clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
