  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

P3485 fault code in automobiles can be caused by various factors, including low oil pressure, restricted oil passage, and faulty solenoids.

  • The automobile fault code P3485 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.

To fix the p3485 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p3485, 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 P3485 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 P3485 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 P3485 code refers to the cylinder 11 exhaust valve control circuit.

The Engine Control Module (ECM) commands cylinder deactivation to improve fuel economy. The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing.

Cylinder deactivation is timed so that the cylinder is on an intake event. The transitions between V8 and V4 mode are seamless and transparent to the vehicle operator.

What are the possible causes of the P3485 automobile fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P3485 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 P3485 fault code?

If you’re experiencing the P3485 fault code, start by checking the possible causes listed above.
