Gear Lever Y Position Sensor 1 Circuit Intermittent/Erratic
What it means
P0824 means the signal from the gear-lever Y position sensor is intermittent or erratic. This sensor reports the shift-lever position on a gated or manual-mode selector; when its signal drops out, the module briefly misreads the selected gear or loses manual-shift function. It won't cause a no-start; the car generally still drives in automatic mode, but the goal is to find the intermittent sensor or wiring fault before it becomes constant.
Can I keep driving? Shifting may occasionally read the wrong gear or lose manual-shift function; usually drivable in automatic mode, but have it checked.

How to diagnose & fix
Work through it in order
- Read freeze-frame data to capture the conditions when it set.
- Wiggle-test the sensor wiring and connector to reproduce the dropout.
- Test the sensor signal across the full travel of the shift lever.
- Secure and clean any loose or corroded connectors.
- Inspect the gear-lever mechanism; replace the sensor if faulty. Clear and re-test.
