P0574 Code: Cruise Control System - Vehicle Speed Too High
🟢 Low severity · drivable
The car drives normally. Cruise control simply won't set when the vehicle is going too fast.
What P0574 means
The cruise control won't turn on because the vehicle is traveling faster than the speed the system allows, often above 100 mph on many cars. This is usually a safety limit rather than a part failure, but the computer records the code anyway.
Symptoms
- Check engine light is on
- Cruise control won't engage at high speed
- Cruise control engages fine at normal speeds
- No other drivability issues
Common causes
- most common: Vehicle driven above the cruise control speed limit
- common: Wrong tire size or gear ratio causing a false speed reading
- less common: Faulty vehicle speed sensor
- rare: Modified computer calibration

| Compare the speedometer reading against a GPS or scan tool | Yes | $0–20 |
