Clutch Position Sensor A Circuit Low
What it means
P0807 means the clutch position sensor A signal is reading below its expected range. On vehicles that use a clutch-position sensor — manuals and automated or dual-clutch transmissions — the control module relies on it to know where the clutch is, so a low signal disrupts clutch engagement and shift control. It's usually a failing sensor or a short-to-ground in the wiring.
Can I keep driving? Usually drivable, but clutch engagement and shifting may be poor; repair soon.

How to diagnose & fix
Work through it in order
- Read freeze-frame data and note any companion clutch or transmission codes.
- Inspect the sensor connector and wiring for a short to ground or an open.
