P062CInternal Control Module Vehicle Speed Performance
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- Electronic throttle systems run a second, independent calculation on the same processor (level 2, at Ford 'IPC – independent plausibility check') that recomputes driver demand, permitted and actual torque and their inputs, and compares them with the main software. Vehicle speed feeds torque monitoring through cruise control, speed limiter and gear-dependent limits. P062C means the module's internal cross-check of vehicle speed fails – main software and monitoring determine it separately, for example from transmission output or wheel speeds, and the values disagree. Ford sets it within 1 s with the wrench lamp; the check engine light came on only on generation 2 (2003–2007), since 2020 not at all. Cruise control and speed limiter are disabled, power may be limited. Ram 6.7 L Cummins (2019) fixed it by reprogramming. No threshold is published. Fix speed sensor codes P0500–P0503 first; a wrong tyre size or axle ratio in the module can also contribute.
- What you may notice
- Wrench lamp (Ford), check engine light only on older Ford
- Cruise control not working
- Possibly reduced power
- Likely causes
- LikelyEngine module software or calibration fault (update available)
- PossibleDisturbed vehicle or output speed signal (sensor, reluctor, ABS CAN data)
- RareWrong tyre size or axle ratio configured in the module
- RareInternal defect of the engine module
- Repair
- Medium · Usually a job for a workshop.Typical cost: €50 – €1,000
