What does code P26E9 mean?

Q: What does code P26E9 mean?

Actuator Supply Voltage D Circuit High. P26E9 indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the actuator supply voltage circuit designated as 'D'. This circuit provides power to one or more actuators, and a high voltage reading suggests a short to voltage, an open ground, or a faulty actuator drawing too little current.
