P3473 OBD-II Trouble Code: Cylinder 10 Deactivation/Intake Valve Control Circuit/Open

Check Engine Light

P3473 code definition

The P3473 code relates to the deactivation mode of cylinder 10. If this code has been stored, it means that the PCM has detected an incorrect range of voltage readings for the cylinder deactivation mode, in comparison to the manufacturer’s specifications.

What the P3473 code means

In order to provide the best fuel economy, the ECM will deactivate certain cylinders during certain driving conditions. During the deactivation command of cylinder 10, a signal is sent to the PCM informing it of the current operation efficiency via a voltage reading. If the voltage reading does not align with the manufacturer specifications, the PCM will store the P3473 code.

What causes the P3473 code?

The underlying cause of the P3473 code can be one of a number of things, including:

  • Low oil pressure
  • Faulty cylinder deactivation solenoid
  • Faulty electrical components within the cylinder deactivation solenoid circuit
  • Restricted oil passage
  • Fault within the engine mechanical condition

What are the symptoms of the P3473 code?

The illumination of the Check Engine Light is the only symptom that is typically observed with the P3473 code.

How does a mechanic diagnose the P3473 code?

After verifying the code with an OBD-II scanner, a mechanic should first perform a visual inspection of all the electrical components, and repair any elements that damaged, corroded, loose, or otherwise inoperable. The code should then be cleared from the PCM, and the system should be retested. If the code returns to the PCM, the mechanic should then proceed to test each potentially faulty component until the proper diagnosis is found.

How serious is the P3473 code?

If the P3473 code is detected, the vehicle needs to be repaired as soon as possible. The fault that causes the P3473 code can quickly create larger issues that will require more expensive repairs in the future.
