If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p3465 fault code. Here are the symptoms to look out for:

  • The P3465 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 performance, rough idling, stalling, or hesitation during acceleration.
  • Additionally, the vehicle may experience a decrease in fuel efficiency, and there may be a noticeable decrease in power when driving uphill or towing.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P3465 fault code can be caused by various factors such as low oil pressure, restricted oil passage, and faulty cylinder deactivation solenoid.

  • The automobile fault code P3465 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 p3465, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p3465, 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 P3465 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of fixing the P3465 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P3465 code refers to the cylinder deactivation system in the engine.

The system deactivates cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank, switching to a V4 mode. Cylinder deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders by using special valve lifters. The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing.

Switching between V8 and V4 mode is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator.

What are the possible causes of the P3465 automobile fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P3465 fault code. This code 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, or 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 P3465 fault code?

To fix the P3465 fault code, start by checking the possible causes listed above. Then, 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 and circuit poor electrical connection.

What are the symptoms of the P3465 automobile fault code?

The P3465 fault code is indicated by the Engine Light ON or Service Engine Soon Warning Light. The possible causes include low oil pressure, restricted oil passage, faulty Cylinder Deactivation Solenoid, and poor electrical connection in the Cylinder Deactivation Solenoid circuit. To fix the issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
