P062C code meaning
Internal Control Module Vehicle Speed Performance
What P062C means
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 tire size or axle ratio in the module can also contribute.
P062C at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P062C
- Wrench lamp (Ford), check engine light only on older Ford
- Cruise control not working
- Possibly reduced power
Common causes of P062C
- Most likelyEngine module software or calibration fault (update available)
- PossibleDisturbed vehicle or output speed signal (sensor, reluctor, ABS CAN data)
- Less likelyWrong tire size or axle ratio configured in the module
- Less likelyInternal defect of the engine module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P062C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6 | Area: computer (engine control module) and output circuits. |
| 2C | The exact fault in that area. |
What to do next
- Note P062C and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P062C
What does P062C mean?
P062C means "Internal Control Module Vehicle Speed Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P062C?
Drive gently and only to a workshop. With P062C the car can go into limp mode (reduced power) to protect itself.
Will P062C fail an emissions test?
P062C is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P062C to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P062C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
