Drive Motor B Position Sensor Circuit High

Where it lives

For P0A48, the sensor sits on the circuit this code reports. The description of P0A48 reports a fault at the sensor.

Check these first

• An open signal wire between the drive motor B position sensor and the control module
• A poor ground at the motor B position sensor
• A failed position sensor inside drive motor B
• A loose or corroded motor B sensor connector
• A short to voltage on the motor B signal wire

What to do next

1. Inspect the motor B sensor connector for looseness or corrosion
2. Check the ground at the drive motor B position sensor
3. Test the signal wire for an open or a short to voltage
4. Watch the motor B position reading on live data while moving the harness
5. Replace the motor B position sensor if the reading stays high
6. Clear the code and retest
