[SOLVED] P3446 Code: Fixing Cylinder 6 Exhaust Valve Control Circuit

The P3446 fault code in automobiles refers to 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 issue 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 to identify the root cause of the problem accurately.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

P3446 fault code can be caused by various factors such as low oil pressure, restricted oil passage, and faulty solenoid.

  • The automobile fault code P3446 can be caused by low oil pressure, restricted oil passage, and engine mechanical condition.
  • It can also be caused by a faulty Cylinder Deactivation Solenoid, an open or shorted Cylinder Deactivation Solenoid harness, and poor electrical connection in the Cylinder Deactivation Solenoid circuit.
  • All of these causes should be considered when diagnosing and fixing the P3446 fault code.

To fix the p3446 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p3446, 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 P3446 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 P3446 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P3446 code refers to the cylinder deactivation system in the engine. The system deactivates certain cylinders to improve fuel economy.

The system deactivates cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank. The deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders.

The system captures exhaust gases in the combustion chamber to reduce oil consumption, noise and vibration levels, and exhaust emissions.

The system switches between V8 and V4 mode in less than 250 milliseconds.

What are the possible causes of the P3446 automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P3446 fault code. The possible causes of this 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 P3446 fault code?

To fix the P3446 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 consequences of ignoring the P3446 fault code?

Ignoring the P3446 fault code, which indicates a problem with the Cylinder Deactivation Solenoid, can lead to serious consequences. The engine light will remain on, indicating a problem with the engine. The cause of the problem could be low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, or a poor electrical connection. To fix the issue, it is important to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
