P0919
Gear Shift Position Control Error
Automated manual transmission / shift position
Generic OBD-II
High
What it means
P0919 means the transmission has detected an error controlling the gear shift position — it can't reliably move to or confirm the commanded gear position. The engine still starts and runs, but shifting may fail or the transmission may enter limp mode, which on an automated-manual gearbox can leave you unable to select gears until it's fixed.
High
Can I keep driving? Shifting may fail or fall into limp mode, potentially leaving you unable to change gears — treat it as urgent and avoid relying on the car.
Common symptoms
What you'll notice
- Check-engine light on
- Difficulty shifting or failure to engage the correct gear
- Harsh or delayed shifts
- Wrong gear shown on the cluster, or transmission in limp mode
Common causes
Most likely first
- Faulty gear shift position sensorLikely
- Malfunctioning gear shift position actuatorCommon
- Wiring or connector fault in the shift position circuitCommon
- Mechanical binding in the shift mechanismLess often
- Failed transmission control module (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and scan for companion shift-position codes.
- Inspect the shift position actuator and sensor connectors and wiring for damage or corrosion.
- Compare commanded versus actual shift position in live data.
- Check the shift mechanism for mechanical binding or wear.
- Test and replace the faulty sensor, actuator, or module, then perform any required adaptation.
FAQ
Quick answers
Is it safe to drive with P0919?+
No — a shift-position control error can prevent proper gear engagement and force limp mode, so get it diagnosed rather than driving on it.
Can I just clear P0919?+
It comes back until the sensor, actuator, or mechanism is repaired, because the module still can't confirm the shift position.
