Circuit C is a third channel reporting the shift position inside an automated manual gearbox, for example a further sensor track or a sensor on another shift rail or selector shaft. This general circuit code sets on an electrical fault of that signal that fits none of the more specific C variants. No manufacturer documents the code publicly, and which sensor carries the letter C depends on the design. A Nissan/Aichi patent describes shift stroke sensors as the feedback for engaging gears, an Aisin AI patent the fallback when a stroke sensor fails. CARB requires circuit checks on such inputs. P095B to P095D are the C siblings, P0914 and P091A the same signal on circuits A and B. Shifting may be restricted.

Likely causes

Loose or corroded connector at shift position sensor C
Damaged signal, supply or ground wire of sensor circuit C
Faulty shift position sensor C
Faulty sensor input in the transmission control module

Symptoms

  • Transmission or engine warning light on
  • Slower or restricted gear changes in fallback mode
  • Gearbox may hold a gear or stay in neutral
