P3403: Unleashing The Mystery Of The Cylinder Deactivation Solenoid Circuit
The P3403 code refers to a low voltage issue in the cylinder 1 deactivation solenoid valve control circuit. This circuit controls the deactivation of engine cylinders 1, 7, 6, and 4 to switch to V4 mode for maximum fuel economy under light load driving conditions. The Engine Control Module (ECM) determines which cylinder is firing and begins deactivation on the next closest deactivated cylinder in the firing order sequence.
Cylinder deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders by using special valve lifters.
Switching between V8 and V4 modes is accomplished in less than 250 milliseconds.
FAQ
If you’re experiencing the P3403 fault code, you may notice that your engine light is on. This could be due to a variety of causes, including low oil pressure, a restricted oil passage, a faulty valve lifter oil manifold assembly, or a poor electrical connection in the valve lifter oil manifold assembly circuit. To fix the issue, it’s important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
If you’re experiencing the P3403 fault code, which is indicated by the engine light being on, it could be due to low oil pressure, a restricted oil passage, a faulty valve lifter oil manifold assembly, or a faulty engine control module.
