P0919Gear Shift Position Control Error
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Set when the control module of an automated manual gearbox drives the shift actuator towards a gear, but the measured shift position does not reach the target within the allowed time and tolerance. Sensor and actuator circuits can be electrically intact; the fault concerns the closed loop as a whole. Usual reasons are a stiff or jammed shift rail or synchroniser, a weak actuator, low hydraulic pressure on hydraulic units, or a sensor offset. No manufacturer documents this code publicly. A Hyundai/Kia patent detects jammed shift actuators from motor current, and an Isuzu patent controls the shift motor by stroke ranges using a shift stroke sensor. CARB requires functional checks on such outputs. P0909 is the same error in the select direction, P0920 to P0927 the actuator circuits. Gears may not engage.
- What you may notice
- Transmission warning light on
- Gear does not engage or engages only after a delay
- Gearbox remains in neutral or locks in one gear
- Likely causes
- LikelyStiff or jammed shift rail, shift fork or synchroniser
- PossibleWorn shift motor or leaking shift cylinder that no longer delivers full force
- PossibleLow pressure in the hydraulic supply on hydraulically actuated units
- RareShift positions not relearned after actuator or module replacement
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
