P3418 is an automobile fault code that triggers the Engine Light ON or Service Engine Soon Warning Light. This code indicates a problem with the cylinder deactivation system in the engine. The cylinder deactivation system is responsible for shutting down some of the engine’s cylinders to improve fuel efficiency.

When the P3418 code appears, it means that the engine control module has detected a problem with the cylinder deactivation system.

This could be due to a faulty solenoid, a wiring issue, or a problem with the engine control module itself. If left unaddressed, the P3418 code can cause reduced fuel efficiency and potentially damage the engine.

It is important to have the issue diagnosed and repaired by a qualified mechanic as soon as possible to avoid further damage and costly repairs.

What are the possible causes of the P3418 automobile fault code?

The P3418 fault code in automobiles can be caused by low oil pressure, restricted oil passage, faulty cylinder deactivation solenoid, or poor electrical connection in the solenoid circuit. It can also be due to engine mechanical conditions or an open or shorted solenoid harness. To fix this issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
