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.
