Code result
P26E9
Actuator Supply Voltage D Circuit High
Moderate severity
What it means
The fourth actuator supply rail is above the expected voltage. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
Most likely causes
Alternator regulator failure
mediumA plausible cause — test and verify before replacing parts.
Wiring shorted to a higher-voltage circuit
lowLess common, but worth ruling out after the more likely causes.
Connector pins corroded - high contact resistance
lowLess common, but worth ruling out after the more likely causes.
