P0914
Gear Shift Position Circuit A
Automated shift position
Generic OBD-II
Medium
What it means
P0914 indicates a fault in the "A" gear shift position circuit. The gear shift position sensor tells the transmission control module where the gear selector is; if that signal is wrong or missing, the module can misread the gear and mismanage shifts. The engine starts and runs normally, but you may get a wrong-gear display, trouble engaging gears, or limp mode. The sensor and its wiring are the most common causes.

How to diagnose & fix
Work through it in order
- Read freeze-frame data and compare the reported gear position with the actual selector position.
- Inspect the gear shift position sensor connector and wiring for corrosion or damage.
- Measure the sensor's signal through its travel against spec.
- Repair loose or corroded connections and secure the harness.
- Replace the position sensor if it fails, then clear the code and road-test.
FAQ
Quick answers
Is it safe to drive with P0914?+
It often drives, but a bad gear-position signal can cause shifting faults or limp mode. Have it diagnosed before depending on the car.
Can I just clear P0914?+
It will return until the sensor or wiring is repaired. Because gear-position data drives shift logic, it's worth fixing properly.
