P095B Gear Shift Position Circuit C Range/Performance

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.

Likely causes

Worn or drifting shift position sensor C disagreeing with the other channels
Bent sensor bracket or displaced magnet on the shift rail
Gear positions not relearned after actuator or module replacement
Increased contact resistance in the sensor circuit

Symptoms

  • Transmission warning light on
  • Harsh or aborted gear changes
  • Fallback mode with fewer available gears
