2006 Dodge Durango 5.7L 4WD with P0459, P1411, P3401, P1521, and P3497 - Shaking at High Speeds & Dashboard Lights Flashing
I recently purchased a 2006 Dodge Durango 4WD with a 5.7L HEMI engine. The vehicle starts shaking noticeably when approaching 30 mph and above, making it feel like it's about to stall. At the same time, multiple dashboard lights begin flashing. A mechanic used an OBD2 scanner and retrieved several diagnostic trouble codes: P0456, P1411, P3401, P1521, and P3497. This issue occurred previously two years ago, when the technician diagnosed a short circuit affecting the engine control module (ECM), which was subsequently replaced. However, the problem has returned. I'm seeking advice on how to properly diagnose and fix these codes, especially since they may be related to engine performance, oil type, or electronic system malfunctions. Key codes: - P0456: EVAP Purge System Small Leak - P1411: Cylinder 1 Reactivation Control Performance Issue - P3401: MDS Solenoid 1 Circuit Fault - P1521: Incorrect Engine Oil Type Detected - P3497: MDS Rationality Bank 2 Error I believe the vehicle is stock with no major aftermarket modifications. The oil pressure and engine performance are both concerning, particularly given the P1521 code indicating an incorrect oil type. A proper scan tool and wiring diagrams would be needed to fully interpret these codes.
These codes are common in older Dodge Durangos, especially with the 5.7L HEMI engine. - P0456: EVAP Purge System Small Leak – indicates a minor leak in the evaporative emissions system; may require inspection of hoses and charcoal canister. - P1521: Incorrect Engine Oil Type Detected – this code suggests that the ECM detected an oil type not within specifications. Using non-approved or incorrect oil (e.g., synthetic blends, wrong viscosity) could trigger this. Switching to OEM-recommended oil may resolve it. - P1411: Cylinder 1 Reactivation Control Performance – points to a potential issue with fuel injection timing or sensor feedback in cylinder 1. - P3401: MDS Solenoid 1 Circuit Fault – relates to the Multi-Discharge System (MDS) solenoid; could indicate wiring issues, faulty solenoid, or ECU miscommunication. - P3497: MDS Rationality Bank 2 – suggests a logic error in the MDS system for bank 2, possibly due to sensor input inconsistencies. The vehicle appears stock with no major modifications. The shaking at high speeds and flashing dashboard lights are likely linked to these codes, especially P1521 (oil type) or P3401/P3497 (MDS issues). A proper OBD2 scanner and wiring diagrams are recommended for accurate diagnosis. Check oil type first – using the wrong oil could cause multiple system errors.
