P2115 Throttle/Pedal Position Sensor D Minimum Stop Performance

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

Here the controller judges position signal D at the released (minimum) end of travel. On Ford and GM drive-by-wire systems D is the first accelerator pedal sensor, so the code means the pedal's idle reading is outside the expected window, for example because the pedal does not return fully or its sensor track has shifted. No manufacturer documents P2115 publicly; Ford and GM publish only circuit and correlation codes for D (P2120-P2123, P2138). P2116 and P2117 are the E and F counterparts, P2109 and P2113 refer to A and B. The engine may not return to idle cleanly, and the ECU may limit pedal response.

Likely causes

Pedal blocked by floor mat or weak return spring
Worn pedal sensor track D at the idle end
Aftermarket pedal tuning module or wrong pedal part
Corroded or loose pedal connector

Symptoms

  • Warning lamp on
  • Engine does not drop to normal idle when the pedal is released
  • Dull or limited pedal response
