Actuator Supply Voltage B Circuit /Open

Where it lives

For P2669, the actuator sits on the circuit this code reports. The description of P2669 reports a fault at the actuator.

Check these first

• An open in the actuator supply voltage B circuit
• A blown fuse feeding the actuator supply voltage B circuit
• A short to ground on the actuator supply voltage B circuit
• A corroded or backed out pin in the actuator supply voltage B connector
• Chafed wiring along the actuator supply voltage B harness

What to do next

1. Read actuator supply voltage B on a scan tool
2. Check the fuse feeding the actuator supply voltage B circuit
3. Measure voltage on the actuator supply voltage B circuit
4. Test the actuator supply voltage B circuit for open and short faults
5. Repair the actuator supply voltage B wiring if the fuse tests good
6. Clear the code and retest
