OBD-II Generic Error Code P0572: How to Fix It

Q: Can I drive with P0572?

It is not recommended because the brake switch signal is used by the ECM for cruise control and shift interlock. A faulty switch may also cause brake lights to malfunction, increasing the risk of rear-end collision.

Q: What causes error code P0572?

Common causes include a faulty brake switch, blown fuse, damaged wiring or connector, corrosion at the switch terminals, or a misadjusted brake pedal switch.

Q: Will P0572 clear itself?

The code may clear on its own if the issue is temporary, but the underlying problem should be fixed to prevent recurrence. If the problem persists, the code will return.

Q: How much does it cost to fix P0572?

Replacing a brake switch typically costs between $20 and $80 for the part, plus labor if done by a shop (1 hour labor). DIY cost is just the part.

Q: Does P0572 affect cruise control?

Yes, the brake switch signal is used to disengage cruise control when the brake is pressed. A faulty switch may prevent cruise control from working or cause it to disengage unexpectedly.
