With P2E11 the position sensor of the gear selection actuator delivers values that are electrically fine but do not fit the situation: the reading stays put although the actuator was driven, or it contradicts the gear that shaft speeds prove to be engaged. No manufacturer documents P2E11 publicly. In GM's TCM tables of 2023 for a dual-clutch box (23OBDG07) one can see how such a plausibility test works on a shift rod sensor under P2832: when speed sensors confirm an engaged gear with more than 600 N of shift force applied, yet the reading lies over 1100 µm from the learned engaged position, a Type A fault follows. Ford's DPS6 flags a comparable loss of confidence in the shift drum position, including a blocked motor, under the same P2832. Typical causes are a shifted sensor magnet, mechanical wear or lost learned values.

Likely causes

Learned end positions lost or outdated, e.g. after battery disconnect or part replacement

Sensor magnet or sensor mounting shifted, reading offset

Wear or binding in the selection mechanism, actuator does not reach its target

Sensor characteristic drifted

Symptoms

Delayed or harsh shifts, gear sometimes not engaged
Transmission warning, possibly limp mode with fixed gear
Fault may clear after a relearn procedure
