What Does P0810 Mean on a Toyota MMT?

The Toyota MMT — Multi-Mode Transmission — is a robotised automated manual gearbox that uses an electromechanical clutch actuator to manage clutch engagement automatically. P0810 — Clutch Position Sensor Circuit — is stored when the actuator's internal position sensor begins to fail, causing the system to detect incorrect clutch position data and default to limp mode.

Toyota MMT clutch actuator failure follows the same pattern as other automated manual gearbox systems — motor wear, sensor degradation and circuit board component failure over time. Our full clutch actuator repair and cloning service covers all Toyota MMT variants.

⚠️ Warranty Terms for This Repair

  • This is a transmission component, and correctly completing the fit requires the correct basic settings, adaptations and teach-in procedure for your specific gearbox to be carried out afterwards for it to operate correctly.
  • Some clutch actuator systems also require clutch bleeding using a professional diagnostic tool as part of a correct installation — this isn't always obvious, so please check what your specific model needs.
  • Please keep proof the installation was completed correctly — a paid invoice from a garage or workshop — as this will be requested if you ever need to make a warranty claim.
  • Many owners with the right diagnostic equipment and experience fit these themselves — that's completely fine. If you're fitting it yourself, keep your own dated records (confirmation the adaptations/teach-in and any required bleeding were completed) as equivalent proof for a claim.
