The P3407 fault code in automobiles indicates a problem with the Cylinder Deactivation System. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code can be low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, or poor electrical connection in the Cylinder Deactivation Solenoid circuit.
The repair importance is high as it can lead to engine damage if not addressed promptly. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.
The repair time is estimated to be around 1.0 hour. It is essential to interpret the fault code correctly to identify the root cause of the problem.

P3407: Unleashing The Mystery Of Faulty Cylinder Deactivation
The P3407 code indicates a problem with the exhaust valve control circuit of cylinder 1. This code is related to the cylinder deactivation system, which switches between V8 and V4 modes to improve fuel economy.
During cylinder deactivation, the ECM commands the deactivation of specific cylinders by not allowing the intake and exhaust valves to open.
The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing. The locking pins are pushed inward with engine oil pressure directed from the valve lifter oil manifold (VLOM) assembly solenoids.
Switching between V8 and V4 mode is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator.
FAQ
If you see the P3407 fault code on your vehicle, it could be due to low oil pressure, restricted oil passage, engine mechanical condition, faulty cylinder deactivation solenoid, or poor electrical connection in the cylinder deactivation solenoid circuit. To fix the issue, inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.
If you’re experiencing the P3407 fault code, start by checking the possible causes listed above. To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues with the Cylinder Deactivation Solenoid harness, which could be open or shorted, or have a poor electrical connection. Once you’ve identified the issue, you can take the necessary steps to fix it.
Ignoring the P3407 fault code, which indicates a problem with the Cylinder Deactivation Solenoid, can lead to serious consequences such as reduced fuel efficiency, engine damage, and even complete engine failure. It is important to address the issue promptly by checking the possible causes, visually inspecting the wiring harness and connectors, and looking for damaged components or corroded pins.
