P210EThrottle/Pedal Position Sensor/Switch C/F Voltage Correlation
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- Engine or throttle warning lamp on
- Reduced power or limp mode
- Hesitant or delayed response to the pedal
- Likely causes
- LikelyOne sensor track worn or drifted, so the pair no longer agrees
- PossibleCorrosion or water in the connector shifting one signal
- PossibleFault in a shared ground or 5 V reference line
- RareFaulty input stage in the engine control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €20 – €600
