Brake Pressure Sensor N Circuit High

Where it lives

For C064E, the circuit described runs through the sensor. The description of C064E reports a fault at the sensor.

Check these first

• A short to voltage in the brake pressure sensor N signal wire
• A brake pressure sensor N that failed high
• A reference voltage fault feeding brake pressure sensor N
• Corrosion or water in the brake pressure sensor N connector
• An ABS module that reads brake pressure sensor N out of range

What to do next

1. Read brake pressure sensor N with a scan tool
2. Test the brake pressure sensor N signal wire for a short to voltage
3. Check the reference voltage at brake pressure sensor N
4. Inspect the brake pressure sensor N connector for corrosion or water
5. Replace brake pressure sensor N if the signal stays high
6. Clear the code and retest
