The Chrysler Code P3497 is a cylinder deactivation system-bank 2, which is an important engine control mechanism. This code is triggered when the engine is making a transition from 8 cylinder mode to 4 cylinder mode, and when the criteria have been met, power is supplied to the MDS Solenoid. In order to ensure that the system is functioning properly, the oil pressure must be sufficient to act on the lifter locking pins. Unfortunately, many times this code is triggered due to insufficient oil pressure, restricted oil passages, a faulty lifter, or a defective MDS Solenoid. To ensure that the Chrysler Code P3497 is working correctly, it is important to understand the causes and possible solutions.
Causes and Solutions of Chrysler Code P3497
| Cause | Solution |
|---|---|
| Inadequate Oil Pressure | Check oil pressure and replace the oil filter if necessary. |
| Restricted Oil Passages | Clean the passages and inspect the gaskets. |
| Lifter Malfunction | Replace the faulty lifter. |
| MDS Solenoid Defect | Replace the defective MDS Solenoid. |
Inadequate Oil Pressure
The Chrysler Code P3497 is triggered when the engine is making a transition from 8 cylinder mode to 4 cylinder mode and the oil pressure is not enough to act on the lifter locking pins. One of the solutions to resolve this problem is to check the oil pressure and replace the oil filter if necessary.
Restricted Oil Passages
Another common cause for this code is restricted oil passages. As the oil is not able to flow freely through the passages, it can cause the engine to misfire. To fix this issue, it is important to clean the passages and inspect the gaskets.
Lifter Malfunction
A faulty lifter is also one of the possible causes of the Chrysler Code P3497. This can be easily resolved by replacing the faulty lifter.
MDS Solenoid Defect
The MDS Solenoid is an important part of the engine control system and if it is defective, it can trigger the Chrysler Code P3497. To resolve this issue, it is important to replace the defective MDS Solenoid.
Conclusion
The Chrysler Code P3497 is a cylinder deactivation system-bank 2, which is an important engine control mechanism. To ensure that the system is functioning properly, it is important to understand the causes and possible solutions. The four main causes of the Chrysler Code P3497 are inadequate oil pressure, restricted oil passages, a faulty lifter, and a defective MDS Solenoid. To resolve these issues, it is necessary to check the oil pressure, clean the passages, replace the faulty lifter, and replace the defective MDS Solenoid. By following these steps, you can ensure that your Chrysler Code P3497 is working correctly.
