Brake Pressure Sensor J Circuit Low

Where it lives

For C063F, the circuit described runs through the sensor. The description of C063F reports a fault at the sensor.

Check these first

• A brake pressure sensor J that failed low
• A short to ground in the brake pressure sensor J signal wire
• Corrosion or water in the brake pressure sensor J connector
• A poor ground at brake pressure sensor J
• An ABS module that lost the brake pressure sensor J signal

What to do next

1. Read brake pressure sensor J with a scan tool
2. Test the brake pressure sensor J signal wire for a short to ground
3. Inspect the brake pressure sensor J connector for corrosion or water
4. Check the brake pressure sensor J ground for resistance
5. Replace brake pressure sensor J if the signal stays low
6. Clear the code and retest
