C0576 — Brake Pressure Sensor D Circuit High

Generic OBD-II · all makesChassis

Code C0576 indicates the electronic brake control module has detected a voltage signal from the brake pressure sensor circuit that exceeds the normal operating range. This condition typically prevents stability control and traction control systems from functioning correctly. The ABS warning lamp will illuminate to alert the driver of the fault.

Symptoms

What causes it — most likely first

1. Failed brake pressure sensor

Internal sensor failure can cause the component to send a permanently high voltage signal to the control module.

2. Short to voltage in sensor wiring

The signal wire may be damaged and contacting a power source, causing the circuit reading to spike.

3. Corroded sensor electrical connector

Moisture or corrosion at the connector can create resistance or false voltage readings.

4. Damaged wiring harness

Physical abrasion or heat damage to the harness near chassis components can expose wires.

5. Hydraulic control unit internal issue

Internal pressure anomalies within the hydraulic unit may affect sensor output readings.

6. Faulty Electronic Brake Control Module

Internal processing errors within the module are possible but statistically rare compared to sensor or wiring faults.

How it's diagnosed

  1. Verify brake fluid level and condition
  2. Inspect sensor wiring and connectors for damage
  3. Measure sensor signal voltage against specifications
  4. Check circuit for short to power source
  5. Replace pressure sensor if component tests fail
  6. Clear codes and verify system operation

Frequently asked

Does this code mean the brake computer needs replacement?

No, module failure is uncommon; the sensor or wiring is usually the root cause.

Is the vehicle safe to drive with code C0576?

Standard braking remains functional, but electronic stability aids will be disabled.

Can this code be caused by a wiring issue?

Yes, a wire shorted to a power source is a frequent cause for circuit high codes.

Will resetting the code fix the problem permanently?

No, the underlying electrical or component fault must be repaired to prevent return.
