P2806 says that the selector position reported by the range sensor and the actual mechanical position of the gearbox do not line up. Ford is the only public user found. Its 2019 hybrid OBD summary lists the code for the eCVT with the wrench lamp and without the MIL; one section defines a park pawl check behind it: if the park motor turns more than 9 radians while the pawl should already be engaged, the code is set. Another section for the same family checks sensor voltages against fixed windows for each position. Common causes are a sensor moved on its shaft after service, a worn selector cable or linkage, or a damaged park mechanism. Re-adjust or replace the sensor and confirm Park holds before driving.

Likely causes

Range sensor not aligned correctly after transmission work
Stretched selector cable or worn linkage
Park pawl or park motor mechanism damaged

Symptoms

  • Wrench lamp, gear display differs from lever position
  • Vehicle may roll in Park
  • Start refused in Park or Neutral
