This code indicates the engine control module has detected a voltage reading below the expected range in the control circuit for the cylinder 6 intake valve deactivation solenoid. This system typically uses oil pressure to disable specific cylinders for fuel economy, and a circuit low condition prevents proper operation. The fault suggests an electrical short or component failure within that specific cylinder's valve control system.
The solenoid coil internal resistance is too low or shorted, triggering the circuit low condition.
Wires leading to the solenoid are chafed, broken, or shorted to ground.
Corrosion or loose pins at the solenoid connector disrupt voltage signals.
Contaminated oil can cause the solenoid to stick or fail electrically over time.
Internal driver failure within the computer is possible but statistically rare compared to component failure.
No, this indicates a hard electrical fault that requires repair to clear.
Rarely. Most cases are caused by the solenoid or wiring, and PCM replacement is usually unnecessary.
Short-term driving is possible, but fuel economy will suffer and long-term engine wear may increase.
Only if the issue is solely due to sludge blocking the solenoid, but electrical faults require component repair.
