DC/DC Converter Temperature Sensor B Circuit

Where it lives

For P0C3D, the circuit described runs through the sensor. The description of P0C3D reports a fault at the sensor.

Check these first

• A failed DC/DC converter temperature sensor B
• An open or short in the sensor B wiring
• Corrosion or water in the sensor B connector
• A hybrid battery pack issue dragging the converter

What to do next

1. Read DC/DC converter temperature sensor B on a scan tool
2. Inspect sensor B and its connector for damage
3. Test the sensor B circuit for an open or short
4. Check the hybrid battery pack
5. Replace sensor B if the circuit tests good
6. Clear the code and retest
