  • To fix the automobile fault code p3416, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and 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 P3416 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 diagnosing and fixing the P3416 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 P3416 code is related to the cylinder deactivation system in the engine. The system deactivates certain cylinders to improve fuel economy.

The code specifically refers to an issue with the control circuit for the exhaust valve on cylinder 2.

This can cause problems with the deactivation process and may result in reduced fuel efficiency.

The system works by using special valve lifters to prevent the intake and exhaust valves from opening on selected cylinders. Switching between V8 and V4 mode is done quickly and seamlessly.

What are the possible causes of the P3416 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P3416 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 poor electrical connection in the cylinder deactivation solenoid circuit. 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 or broken, bent, pushed out, or corroded connector’s pins.
