DC/DC Converter Current Sensor C Circuit

Where it lives

For P0EA0, the circuit described runs through the sensor. The description of P0EA0 reports a fault at the sensor.

Check these first

• An open or short in the DC/DC converter current sensor C circuit
• A failed current sensor C
• A backed out pin at the current sensor C connector
• Chafed wiring along the sensor C harness

What to do next

1. Read DC/DC converter current sensor C on a scan tool
2. Test the sensor C circuit for open and short faults
3. Check the sensor C connector pins
4. Measure the current sensor C resistance
5. Replace the current sensor C if faulty
6. Clear the code and retest
