P0806
Clutch Position Sensor A Circuit Range/Performance
Transmission / clutch position
Generic OBD-II
Medium
What it means
P0806 means the clutch position sensor's signal is present but out of its expected range or not tracking clutch travel correctly. On automated-manual and dual-clutch transmissions the module relies on this reading to engage gears smoothly, so a bad signal usually causes harsh or hesitant engagement and can trigger limp mode.
Medium
Can I keep driving? Usually drivable but gear engagement may be harsh or hesitant and the transmission may enter limp mode — fine to reach a shop, don't delay the repair.

Common causes
Most likely first
- Failed or out-of-range clutch position sensorLikely
- Damaged wiring or a corroded connector at the sensorCommon
- Clutch actuator wear or a mis-set clutch position (adaptation)Common
- Sensor mounting or mechanical alignment issueLess often
- Failed transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Scan for codes and read freeze-frame data to confirm the fault.
- Inspect the sensor wiring and connector for damage, corrosion, or loose pins.
- Compare the live clutch-position reading on a scan tool against the actual clutch travel.
- Check the sensor mounting/alignment and perform any required clutch adaptation relearn.
- Replace the sensor if it reads out of range; suspect the actuator or TCM only if the sensor and wiring are good. Clear and re-test.
