P095D Gear Shift Position Circuit C High

Drive cycleNot required
Limp modePossible

Shift position sensor C of an automated manual gearbox delivers a voltage above its permitted window. This usually points to a signal wire shorted to the supply, a broken sensor ground or, with a pulled-up input, an interrupted signal line. Since no real shift position produces such a value, the module can set the code without cross-checking other channels. No manufacturer documents this code publicly. A Nissan/Aichi patent describes shift stroke sensors as feedback for gear engagement, an Aisin AI patent how control continues when one of them fails. CARB requires circuit checks on such inputs. P095C is the low counterpart, P095A the general and P095B the plausibility fault; P0917 and P091D are the high faults of A and B.

Likely causes

Signal wire of sensor C shorted to the 5 V supply or battery voltage
Open ground circuit of the sensor
Internally failed shift position sensor C

Symptoms

  • Transmission or engine warning light on
  • Fallback mode with restricted gears
  • Jerky or aborted gear changes
