C0562Brake Pedal Position Sensor Supply Voltage Circuit/Open

Q: What does code C0562 mean?

Brake Pedal Position Sensor Supply Voltage Circuit/Open. C0562 means the electronic brake control module (EBCM) has detected an open circuit or abnormal voltage on the power supply wire feeding the brake pedal position sensor. The sensor itself may be fine; the module is reporting that the voltage it expects to see on that supply circuit is missing or out of range, which prevents it from reliably knowing where the brake pedal is.

Symptoms you may notice

Anti-lock brake (ABS) warning light illuminated on the dashboard
Traction control or stability control warning light also on, since these systems share the brake pedal position signal
Brake pedal feels normal but cruise control may not disengage when the pedal is pressed
Reduced or disabled ABS and stability control function during braking
Often no symptoms besides the warning light, with normal brake pedal feel and stopping performance
In some vehicles, the transmission may not shift out of park or the brake lights may behave erratically

Common causes, most likely first

Broken, chafed, or corroded wire in the brake pedal position sensor supply circuit
Loose or contaminated connector at the brake pedal position sensor or at the electronic brake control module
Failed brake pedal position sensor with an internal open on its supply side
Blown fuse or faulty relay feeding the sensor supply circuit
Poor ground connection shared by the sensor or the brake control module
Water intrusion or corrosion in the harness near the pedal assembly or firewall
Failed electronic brake control module (less common but possible)

How to diagnose and fix it

Scan all modules for codes and record freeze-frame data to confirm C0562 is current and not history
Inspect the brake pedal position sensor connector and the EBCM connector for looseness, corrosion, or pushed-out pins
Check the fuse and relay that supply power to the brake pedal position sensor circuit, replacing any blown fuse after finding the cause
Measure voltage on the sensor supply wire with the key on and the connector unplugged, comparing to the manufacturer's specified range
Perform a voltage drop test on the supply wire and ground circuit while loaded to reveal a high-resistance open
Wiggle-test the harness while watching live sensor data to catch an intermittent open before condemning parts
If the circuit tests good, substitute a known-good sensor and recheck; replace the EBCM only after all wiring and sensor checks pass

What the supply circuit code really tells you

C0562 is a circuit code, not a sensor performance code, so replacing the brake pedal position sensor first often fails to fix it because the open is in the wiring or connector.
A corroded connector pin or a chafed wire behind the pedal assembly is a far more common cause than a failed sensor or module, especially on older vehicles.
The same supply circuit often feeds other sensors, so a shared fuse or splice can set C0562 together with codes for other systems.
Intermittent C0562 that appears only over bumps or when the pedal is moved points to a harness flex point, not an internal sensor failure.
Some vehicles will disable cruise control and hill-start assist when this code is set, even though base braking still works normally.

Can I keep driving with C0562?

The base hydraulic brakes still work, so the car is driveable to a shop, but ABS and stability control may be disabled and should not be relied on in an emergency stop. Avoid towing, heavy loads, or slippery conditions until the circuit is repaired.
