What does code P2671 mean?

Q: What does code P2671 mean?

Actuator Supply Voltage 'B' Circuit High. P2671 means the powertrain control module (PCM) has detected that the voltage on the actuator supply voltage 'B' circuit is higher than the expected range, typically near battery voltage when the circuit should be at or near ground. This high-voltage condition indicates an open circuit, a short to voltage, or a faulty actuator that is not drawing the current the PCM expects.
