P210E Throttle/Pedal Position Sensor/Switch C/F Voltage Correlation

P210E compares two redundant position signals, C and F, and sets when their voltages stop agreeing within the permitted tolerance. Which physical tracks carry these letters is up to the manufacturer: GM's 2023 table 23OBDG07 uses C for the first sensor of a second throttle body, while Ford's summaries assign D, E and F to the three tracks of its pedal, so a C/F pair only arises on unusual layouts. No manufacturer documents this code publicly. The same kind of check is documented under P2138: GM's 2023 table flags the D/E pedal pair at a difference of 0.12-0.18 V, the 2014 VW Touareg at 0.14-0.26 V. A single drifting track, contact resistance or a shared ground fault is the usual cause; the ECU then trusts neither signal fully and limits power.

Likely causes

One sensor track worn or drifted, so the pair no longer agrees
Corrosion or water in the connector shifting one signal
Fault in a shared ground or 5 V reference line
Faulty input stage in the engine control module

Symptoms

  • Engine or throttle warning lamp on
  • Reduced power or limp mode
  • Hesitant or delayed response to the pedal
