P0574 Code: Cruise Control System Vehicle Speed Too High
The P0574 code means the vehicle speed went above the limit allowed for cruise control, so the system turned itself off. It is usually just informational. If it keeps coming back without going over that speed, suspect the speed sensor.

What the P0574 code means
Cruise control has a maximum operating speed. If that speed is exceeded (on a steep downhill, for example), the computer shuts the system off and stores the P0574 code. If it happens without exceeding that speed, suspect the speed sensor.
Clear the code and check whether it comes back under normal conditions.
If the P0574 code shows up often without you going over the maximum speed, compare the scan tool speed with a GPS. A constant difference points to a tire size different from the one programmed, or to a speed sensor giving wrong readings.
