A/C Compressor Motor Phase W Current Sensor Circuit High

Where it lives

For P0EB8, the sensor sits on the circuit this code reports. The description of P0EB8 reports a fault at the sensor.

Check these first

• A short to voltage on the phase W current sensor signal wire
• A failed phase W current sensor reading high
• A compressor motor phase W drawing excess current
• Corrosion at the phase W sensor connector

What to do next

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