DC/DC Converter Current Sensor B Circuit High

Where it lives

For P0E9E, the sensor sits on the circuit this code reports. The description of P0E9E reports a fault at the sensor.

Check these first

• A short to voltage on the current sensor B signal wire
• A failed current sensor B reading high
• A DC/DC converter drawing excess current
• Corrosion at the current sensor B connector

What to do next

1. Read DC/DC converter current sensor B on a scan tool
2. Test the sensor B signal wire for a short to voltage
3. Measure converter current with a clamp meter
4. Check the sensor B connector for corrosion
5. Replace the current sensor B if the circuit tests good
6. Clear the code and retest
