P3401 DODGE Possible Causes
- Low oil pressure
- Restricted oil passage
- Engine mechanical condition
- Faulty Multiple Displacement System (MDS) Solenoid
- Multiple Displacement System (MDS) Solenoid harness is open or shorted
- Multiple Displacement System (MDS) Solenoid circuit poor electrical connection
How do I fix code P3401 DODGE?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- Although in some cases changing the engine oil may fix the problem, usually the Multi Displacement System Solenoid may need to replaced.
Cost of diagnosing the P3401 DODGE code
The cost of diagnosing the P3401 DODGE code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
The ECM has detected a fault in the MDS solenoid circuit
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P3401 DODGE Description
When all the criteria has been met,power is supplied to each Multi-Displacement System (MDS) Solenoid when engine is making a transition from 8 cylinder mode to 4 cylinder mode. By actuating the solenoid, oil pressure is raised to the pair of lifter that coincide with each particular solenoid. The oil pressure pushes in the locking pins that allows the lifter to collapse, decoupling the valves and camshafts.
