The P3440 fault code in automobiles refers to 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 issue 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 left unaddressed.
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 accurately.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 10.0 (Out of 10) |

P3440: The Lowdown On Your Engine’s Camshaft Position Sensor
The P3440 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 5. This can cause problems with oil consumption, noise, and emissions.
The system switches between V8 and V4 modes quickly and seamlessly.
The ECM limits cylinder deactivation to 10 minutes in V4 mode before returning to V8 mode for 1 minute.
