P104A Dodge Code - Cylinder 3 Oil Supply Solenoid Valve Overcurrent
Quick Answer
Multi-Air is an electronically controlled variable intake valve phase and lift system. Common causes include Faulty Variable Valve Actuator (VVA) Solenoid, Variable Valve Actuator Solenoid harness is open or shorted, Variable Valve Actuator Solenoid circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P104A Dodge Description
The Multi-Air valve train has a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The VVA Solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event, the VVA Solenoid is commanded to either hold oil pressure or bleed oil. The Variable Valve Actuator (VVA) Solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA Solenoid determines the intake valve timing and lift. This change on valve action is similar to creating a change in the camshaft lobe profile affecting the lift and duration of the valve opening. The Diagnostic Trouble Code (DTC) will be set when the Variable Valve Actuator (VVA) solenoid current feedback level in voltage is out of range.

Frequently Asked Questions about P104A Dodge Code
What does the OBDII code P104A mean on a Dodge vehicle?
The P104A code indicates an overcurrent condition in the Cylinder 3 Oil Supply Solenoid Valve circuit, which controls oil flow to Cylinder 3 for variable valve timing or cylinder deactivation.
What are the common symptoms of a P104A code?
Symptoms may include an illuminated check engine light, reduced engine performance, poor fuel efficiency, rough idling, or noticeable engine misfires.
What causes the P104A code to appear?
Common causes include a faulty Cylinder 3 Oil Supply Solenoid Valve, damaged wiring or connectors in the solenoid circuit, or an issue with the vehicle's powertrain control module (PCM).
Can I still drive my Dodge with a P104A code?
While the vehicle may still run, driving with this code can cause poor performance and potentially lead to engine damage if the oil flow to Cylinder 3 is compromised.
How can I diagnose the P104A code?
Start by inspecting the solenoid valve’s wiring and connectors for damage. Use a multimeter to check for proper voltage and continuity. If no issues are found, test or replace the solenoid itself.
What tools are needed to fix a P104A code?
You may need an OBDII scanner, a multimeter, basic hand tools, and potentially replacement parts such as the solenoid valve or wiring components.
How much does it cost to repair the P104A code?
Repair costs can vary, but replacing the oil supply solenoid valve typically costs between $100 and $300, including parts and labor, depending on your location and vehicle model.
Can a dirty or low oil level cause the P104A code?
Yes, insufficient or contaminated oil can affect the solenoid's operation. Always check your oil level and quality before performing further diagnostics.
Does the P104A code affect all Dodge models the same way?
The symptoms and repair process may vary slightly depending on the Dodge model and engine, but the general cause and troubleshooting steps are similar.
Should I clear the P104A code after repairs?
Yes, after completing repairs, clear the code with an OBDII scanner and test drive the vehicle to ensure the issue is resolved and the code does not return.
