P0810
Clutch Position Control ErrorP0810 is a generic OBD-II powertrain diagnostic trouble code: Clutch Position Control Error. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.
What P0810 means
P0810 is set when the control module decides that clutch position is not behaving the way it should. Unlike the pure circuit codes P0807 and P0808, this is a plausibility or performance fault: the module compares the clutch position it expects, or has commanded, against the position the sensor actually reports, and stores the code when the two disagree by more than the calibrated tolerance, or when the clutch moves too slowly to reach the target in time.
On a conventional manual gearbox the module is watching the clutch pedal position sensor and cross-checking it against engine speed, gearbox input speed and the clutch switch, so a sticking pedal, a mis-set sensor or a mechanically dragging clutch can all trigger it. On automated manual and twin-clutch gearboxes the module actively commands a clutch actuator and monitors its feedback, so a sticking or worn actuator, low hydraulic pressure, a lost adaptation or a clutch that no longer bites where the module expects will set the code.
Because clutch position drives engagement strategy and the starter interlock, the consequences can be more than a warning lamp. Automated gearboxes commonly go into a protective limp strategy with reduced gears or refuse to select a gear at all, and some vehicles will not crank. Faults of this type usually need a clutch adaptation or relearn after any repair.
Common causes
Most-frequently reported root causes when P0810 is logged.
-
1
Sticking, worn or failing clutch actuator on an automated manual or twin-clutch gearbox.
-
2
Clutch position sensor out of adjustment or reporting a drifted signal so the module's expected and actual positions never agree.
-
3
Lost or corrupted clutch adaptation values after a clutch, actuator or module replacement.
-
4
Worn clutch disc or pressure plate that shifts the engagement point outside the learned window.
-
5
Mechanical binding in the clutch pedal assembly, cable, release bearing or fork.
-
6
Low fluid, air or internal leakage in a hydraulically operated clutch or actuator circuit.
-
7
Damaged wiring or a corroded connector between the module and the clutch sensor or actuator.
-
8
Faulty engine or transmission control module, which is uncommon and only after the mechanical and electrical checks pass.

How to diagnose P0810
A typical diagnostic flow when this code is present.
-
1
Read all stored codes and freeze-frame data and record whether clutch circuit codes such as P0807 or P0808 are present, because those must be repaired first.
-
2
Check clutch fluid level and look for external leaks at the master cylinder, slave cylinder or actuator before doing any electrical testing.
-
3
Watch clutch position, commanded position and clutch engagement point on live data while operating the clutch, and note whether actual position follows the command.
-
4
Inspect the clutch pedal assembly, cable or linkage, and the sensor mounting, for binding, wear or misalignment that would shift the reported position.
-
5
Inspect the wiring and connectors between the module, the clutch position sensor and the actuator for chafing, corrosion, moisture and loose terminals, wiggling the harness while watching live data.
-
6
Run the manufacturer's clutch adaptation or relearn procedure, then clear the code and retest on a road drive to see whether the fault returns.
-
7
If the code returns with the adaptation complete and the wiring proven good, test the actuator's response and the mechanical condition of the clutch against the manufacturer's specification before replacing anything.

Frequently asked questions
Can I keep driving with P0810?
It is best not to drive far. The code often comes with a limp strategy or unpredictable clutch engagement, so the car may lose drive, refuse to select a gear or stall in traffic. On an automated manual or twin-clutch gearbox, continuing to drive with a mis-controlled clutch can accelerate clutch and actuator wear.
Will P0810 fail an emissions test?
The fault is not an emissions defect, but the illuminated check engine light fails the visual inspection in most testing regimes. The code has to be repaired and cleared, not just erased, before the test.
Does P0810 mean I need a new clutch?
Not necessarily. A worn clutch is one cause, but a mis-adjusted sensor, a lost adaptation, a sticking actuator, low fluid or a wiring fault can all set the same code. A clutch adaptation and a proper live-data check should be done before any clutch is condemned.
Is P0810 expensive to fix?
It varies widely. A relearn, a fluid top-up or a connector repair is cheap, while a clutch actuator or a clutch replacement on a twin-clutch gearbox is one of the more expensive drivetrain jobs. Accurate diagnosis is what keeps the bill down.
Disabling P0810 in software
RaceTune can permanently disable P0810 — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.
ECU families we can disable P0810 on
We hold the DaVinci A2L disable definitions for these families, so the exact P0810 path and mask addresses are mapped. verified marks a confirmed disable definition. We support many more — upload your file and our identifier will match it automatically.
