The P3454 fault code in automobiles indicates 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 fault code 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 and take appropriate action.

P3454: The Low Cylinder Deactivation Solenoid Circuit – Explained
The P3454 code relates to the cylinder deactivation system in the engine. The system deactivates cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank, switching to a V4 mode. The system deactivates the exhaust valve first, allowing the capture of a burnt airfuel charge or exhaust gas charge in the combustion chamber.
The transitions between V8 and V4 mode are seamless and transparent to the vehicle operator, taking less than 250 milliseconds. The ECM calibrations limit cylinder deactivation to a cycle time of 10 minutes in V4 mode, and then return to V8 mode for 1 minute.
FAQ
If you see the engine light on or service engine soon warning light, it could be due to the P3454 fault code. This code is 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.
If you’re experiencing the P3454 fault code, start by checking for low oil pressure, restricted oil passage, or engine mechanical issues.
