P2165 belongs to the rarely used letter C. It is set when position signal C, at the upper stop of its throttle or pedal, reports a value the controller cannot accept as full travel. Since Ford gives A and B to the throttle and D to F to the pedal, C only appears on layouts with a third sensor track or a different naming scheme. No manufacturer documents P2165 publicly; the description follows the A version P2163, which Ford lists, and a Visteon patent on learning the throttle's open stop. Before replacing parts, confirm that the vehicle really uses a sensor C; an aftermarket throttle body or pedal with a different characteristic can also produce the code. P2114 tests the closed stop of C, P2136/P2137 compare C with A or B.

Likely causes

Sensor C track worn at the end of travel
Replacement throttle or pedal with a different characteristic
Mechanical obstruction before the upper stop
Resistance in the sensor C wiring or connector

Symptoms

  • Engine warning lamp on
  • Reduced power at full load
