P0917 Gear Shift Position Circuit A High

Check engine lightOn

EmissionsRelevant

Drive cycleNot required

Limp modePossible

Set when the gear shift position signal on circuit A of an automated manual gearbox stays above its highest valid value for longer than a calibrated time. The signal line may be shorted to the sensor supply or to battery voltage, the sensor ground may be open, or the sensor itself may be faulty. No manufacturer documents this code publicly. The Aisin AI and Nissan/Aichi patents show the shift stroke or shift position sensor as the feedback that confirms an engaged gear; with a reading above the valid band the controller can no longer tell neutral from an engaged gear. CARB requires out-of-range checks on such inputs. P0916 is the opposite low fault, P091D and P095D are the high faults of circuits B and C, P0919 a shift movement that misses its target. Shifting is usually locked.

Likely causes

Signal wire shorted to sensor supply or battery voltage

Open sensor ground or corroded ground pin

Internal fault of the shift position sensor

Faulty input stage in the transmission control module

Symptoms

Check engine or transmission warning light on
Gearbox stays in one gear or in neutral
Warning message about the transmission on the dashboard
