Common Symptoms
- Check Engine Light illuminated
- Engine may run in limp mode with reduced power
- Poor engine performance or hesitation
- Rough idle or stalling
- Transmission may not shift properly if TCM affected
Most Likely Root Causes
- Faulty powertrain control module internal voltage regulator
- Damaged or corroded wiring harness to actuators
- Short to ground in actuator supply circuit
- Failed solenoid or actuator drawing excessive current

Component Location
The actuator supply voltage circuit originates from the PCM and distributes power to various engine and transmission solenoids throughout the vehicle.
Manufacturer Notes
This code indicates the PCM has detected the internal actuator supply voltage circuit is below the expected threshold during operation.
