P3428: The Low-Pressure Fuel System Sensor Circuit – Explained
The P3428 code relates to the cylinder deactivation system in the engine. It indicates that there is a high voltage issue with the solenoid valve control circuit for cylinder 4.
The engine control module commands cylinder deactivation to improve fuel economy under light load conditions.
Deactivation is achieved by not allowing intake and exhaust valves to open on selected cylinders using special valve lifters. Switching between V8 and V4 modes is seamless and takes less than 250 milliseconds.
