What Does P0810 Mean?
A Clutch Position Control Error has been detected. The PCM or TCM has determined that the actual clutch engagement position does not match the commanded or expected position. This code is common in automated manual transmissions (AMTs), dual-clutch transmissions (DCTs), and some semi-automatic systems where the clutch is actuated by the control module rather than the driver. The clutch actuator is not achieving its target position.
Safety Warning
This can cause unexpected vehicle behavior including stalling, lurching, or inability to engage gears. If the clutch is not engaging properly, the vehicle may not be safe to drive. Have it towed if shift quality is severely degraded.
Common Causes
30%
Clutch actuator motor or hydraulic servo failure
25%
Low clutch actuator hydraulic fluid or air in the system
20%
Worn clutch disc reducing effective travel range
15%
Clutch position sensor providing incorrect feedback to the TCM
10%
TCM software calibration issue or adaptation values corrupted
Diagnostic Steps
1
Monitor commanded vs. actual clutch position on the scan tool during clutch engagement — a significant deviation confirms the control error.
2
Check the clutch actuator hydraulic fluid level and inspect for leaks in the hydraulic lines, slave cylinder, and actuator body.
3
Perform a clutch actuator adaptation/calibration procedure using the scan tool to re-learn the clutch engagement point.
4
Monitor clutch wear parameters if available — excessive wear can move the engagement point beyond the actuator's adjustment range.
5
Test the clutch actuator motor by commanding it through its full range and measuring current draw — erratic or excessive current indicates a mechanical binding.

The most common cause of P0810 (Clutch Position Control Error) is: Clutch actuator motor or hydraulic servo failure
Typical repair costs for P0810 range from $200 to $3,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This can cause unexpected vehicle behavior including stalling, lurching, or inability to engage gears. If the clutch is not engaging properly, the vehicle may not be safe to drive. Have it towed if shift quality is severely degraded.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0810 to identify the root cause.
