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.

P0574 code symptoms

  • Cruise control that shuts off.
  • Check engine light on.

Likely causes of the P0574 code

  1. Actual speed too high on a downhill.
  2. Speed sensor giving wrong readings. The computer thinks the vehicle is going faster.
  3. Tire size that was not programmed. It changes the calculated speed.

How to diagnose the P0574 code step by step

  1. Compare the scan tool speed with a GPS.
  2. Check the speed sensor.

How to fix the P0574 code

  • Clear the code.
  • Repair the sensor if it is failing.

Technical reference data

  • Look up the maximum cruise control speed for your vehicle.
  • Reference values only: check the manufacturer data for your vehicle.

Frequently asked questions about P0574

Is it serious?
No. It is usually informational, and cruise control simply turns itself off when the speed limit for the system is exceeded.
Why does cruise control turn off?
For safety, when the speed goes above the limit the system is designed for.
Can I drive with a P0574 code?
Yes. The vehicle drives normally. Only cruise control is affected, and only until you clear the code.
How much does it cost to fix P0574?
Normally nothing. If a speed sensor has to be repaired, expect up to about $150.
What does the P0574 code mean?
The P0574 code is a generic OBD2 code that tells you the vehicle went faster than the speed cruise control is allowed to work at. It is stored when the system shuts off for that reason.
