P062C: Vehicle-speed supervision is not simply a missing speed-sensor signal

P062C is listed by Ford as internal control module vehicle speed performance, with expanded form P0720_48. Its location in electronic-throttle supervision indicates an internal performance check involving vehicle-speed information, rather than automatically a direct open circuit at a speed sensor.

Keep the monitored function attached to the code

The source separately lists internal engine-speed, torque and airmass performance results. The vehicle-speed category therefore matters when organizing the complete diagnostic record. Preserve the full code format and any associated sensor, communication or processor faults before deciding which input or controller function requires investigation.

The summary does not publish a numerical discrepancy threshold for P062C or identify a universal speed-signal source. Different vehicle configurations must be resolved through the matching service information.

A missing MIL does not clear the concern

Ford marks this result as non-MIL with a wrench indication. The monitoring group is continuous and generally lists a sub-second detection period. The absence of a check-engine lamp is consequently not proof that the supervisory result has disappeared.

A plausible vehicle-speed value on one scan-tool screen also does not verify every internal comparison that uses it. Post-repair verification should demonstrate a completed, healthy supervisory check and consistent relevant input data. The source provides no blanket instruction to replace a transmission speed sensor or PCM, and its general fallback descriptions should not be treated as a guaranteed behavior for this individual code.

Source and applicability

This explanation covers the cited Ford monitor variants, not every vehicle displaying this code. Match the engine, sensor architecture and calibration before applying numerical limits.
