[SOLVED] P3414 Code: Fixing Cylinder 2 Exhaust Valve Control Circuit Performance

The P3414 fault code in automobiles indicates a problem with the Cylinder Deactivation Solenoid. The symptom is the Engine Light ON or Service Engine Soon Warning Light. The cause could be low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, Cylinder Deactivation Solenoid harness is open or shorted, or Cylinder Deactivation Solenoid circuit poor electrical connection.

The repair importance is high as it affects the engine’s performance.

The repair difficulty is moderate, and the fix involves visually inspecting the related 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 1.0 hour. To interpret the fault code, one needs to check the possible causes listed above.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p3414 fault code.

Here are the symptoms to look out for:

  • The P3414 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, rough idling, stalling, and poor acceleration.
  • Additionally, the vehicle may experience misfires, reduced fuel efficiency, and difficulty starting.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P3414 fault code in automobiles can be caused by various factors, including low oil pressure, restricted oil passage, and faulty cylinder deactivation solenoid.

  • The automobile fault code P3414 can be caused by low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, Cylinder Deactivation Solenoid harness being open or shorted, and Cylinder Deactivation Solenoid circuit having poor electrical connection.

Below are the possible fixes for the automobile fault code p3414, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p3414, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P3414 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P3414 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P3414 code refers to the cylinder deactivation system in the engine. The system deactivates certain cylinders to improve fuel economy.

The ECM commands the deactivation of cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank. The deactivation is achieved by not allowing the intake and exhaust valves to open on the selected cylinders. 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.

The switching between V8 and V4 mode is accomplished in less than 250 milliseconds.

What are the possible causes of the P3414 automobile fault code?

If you see the P3414 fault code on your vehicle, it means that the engine light is on. The possible causes of this fault code include low oil pressure, restricted oil passage, engine mechanical condition, faulty cylinder deactivation solenoid, cylinder deactivation solenoid harness is open or shorted, and cylinder deactivation solenoid circuit poor electrical connection. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P3414 fault code?

If you’re experiencing the P3414 fault code, start by checking the possible causes listed above.
