[SOLVED] P3464 Code: Fixing High Exhaust Valve Control Circuit In Cylinder 8

The P3464 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. It is essential to check the possible causes listed above to interpret the fault code accurately.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of p3464 fault code.

Here are the symptoms to look out for:

  • The P3464 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 reduced engine power, engine misfires, rough idling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience hesitation or stalling during acceleration, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

The P3464 automobile fault code can be caused by various factors, including low oil pressure and faulty solenoids.

  • The automobile fault code P3464 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.
  • It is important to identify the specific cause of the fault code in order to properly diagnose and fix the issue.

Below are the possible fixes for the automobile fault code p3464, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code p3464, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check 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 P3464 diagnosis and fixing cost is influenced by several factors.

The estimated repair time for this code is 1.0 hour.

The cost of repair is commonly charged between $75 and $150 per hour by most auto repair shops. These factors play a significant role in determining the overall cost of fixing the P3464 fault code.

It is important to consider these factors before taking your vehicle for repair to avoid any surprises in the final bill.

The P3464 code is related to the cylinder deactivation system in the engine.

The system deactivates certain cylinders to improve fuel economy under light load driving conditions.

The ECM commands the deactivation of cylinders 1, 4, 6, and 7.

The deactivation is achieved by not allowing the intake and exhaust valves to open on the selected cylinders.

The code indicates that there is a high circuit in the exhaust valve control for cylinder 8.

The exhaust valve for the deactivated cylinder is closed to capture exhaust gases in the combustion chamber.

The transitions between V8 and V4 mode are seamless and take less than 250 milliseconds.

What are the possible causes of the P3464 automobile fault code?

If you see the P3464 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 P3464 fault code?

If you’re experiencing the P3464 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.

What are the consequences of ignoring the P3464 fault code?

Ignoring the P3464 fault code, which indicates low oil pressure, restricted oil passage, or faulty cylinder deactivation solenoid, can lead to serious engine damage. The engine light will remain on, and the vehicle may experience reduced performance and fuel efficiency. It is important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins to avoid further damage.
