P0806

Clutch Position Sensor A Circuit Range/Performance

Q: Is it safe to drive with P0806?

You can usually drive it to a shop, but poor clutch engagement or limp mode means you should keep trips short until it's repaired.

Q: Can I just clear P0806?

It will clear, but returns once the module sees the out-of-range clutch signal again unless the sensor or wiring is fixed.

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 symptoms

What you'll notice

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

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.
