Generator Voltage Sense Circuit B High

Check these first

• A generator voltage sense circuit B reading higher than expected
• A short to voltage on the sense B wire
• An open in the sense B ground
• A sense B connector shorted to a live circuit

What to do next

1. Read generator voltage sense B on a scan tool
2. Test the sense B wire for a short to voltage
3. Check the sense B ground for continuity
4. Inspect the sense B connector
5. Replace the generator control module if the sense stays high
6. Clear the code and retest
