Brake Pressure Sensor J Circuit/Open

Where it lives

For C063D, the circuit described runs through the sensor. The description of C063D reports the sensor as open.

Check these first

• An open in the brake pressure sensor J signal circuit
• A failed brake pressure sensor J
• Corrosion or damage at the brake pressure sensor J connector
• A broken wire in the brake pressure sensor J harness
• An ABS module that cannot read brake pressure sensor J

What to do next

1. Read brake pressure sensor J with a scan tool
2. Test the brake pressure sensor J signal circuit for an open
3. Inspect the brake pressure sensor J connector and wiring
4. Check the brake pressure sensor J reference and ground
5. Replace brake pressure sensor J if the circuit tests good
6. Clear the code and retest
