The code covers the rest-position check of signal E. Ford, GM and Mitsubishi assign E to the second accelerator pedal sensor, which on many pedals runs at roughly half the voltage of sensor D (GM: APP 2 between 0.16 and 2.3 V). If the reading with the pedal released lies outside the learned or calibrated window, P2116 can be stored. No manufacturer documents this code publicly. Circuit faults of the same sensor are reported separately (P2125, P2127-P2129) and disagreement between D and E as P2138; P2115 and P2117 handle D and F. Typical effects are a warning lamp, an unsteady idle and limited throttle response.

Likely causes

Pedal held off its stop by floor mat or sticking pivot
Worn or contaminated sensor track E
Moisture or corrosion at the pedal connector

Symptoms

  • Warning lamp on
  • Unsteady or raised idle
  • Limited throttle response
