Code P103F 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 PCM detects a short to voltage in the Solenoid Signal or Return circuit.

Frequently Asked Questions about P103F Dodge Code
1. What does the OBDII code P103F mean for a Dodge vehicle?
The P103F code indicates a "Cylinder 4 Oil Supply Solenoid Valve Driver Short To Battery," meaning a fault in the circuit controlling the oil supply solenoid for cylinder 4.
2. What are the common symptoms of code P103F in a Dodge?
Symptoms may include a check engine light, rough engine performance, decreased fuel efficiency, misfires, or unusual engine noises.
3. What causes the P103F code to appear?
Potential causes include damaged wiring, a short circuit in the oil supply solenoid valve circuit, a faulty oil control solenoid, or an issue with the engine control module (ECM).
4. Can I drive my Dodge with the P103F code?
Driving with this code is not recommended, as it can cause improper oil flow to the affected cylinder and potentially damage the engine.
5. How do I diagnose the P103F code?
Diagnose the code by inspecting the wiring and connectors for damage, testing the solenoid valve for proper function, and checking for voltage or continuity issues in the circuit.
6. What tools are needed to fix the P103F code?
Tools may include an OBDII scanner, a multimeter, and basic hand tools to inspect, test, and repair wiring or replace components.
7. How is the P103F code fixed?
Repairs may involve replacing the cylinder 4 oil supply solenoid valve, repairing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
8. How much does it cost to fix code P103F on a Dodge?
Repair costs can vary, but replacing an oil control solenoid typically costs $100–$300 for parts and labor, while ECM-related repairs may be more expensive.
9. Can a dirty oil system cause the P103F code?
Yes, dirty or contaminated oil can cause the solenoid to malfunction, so an oil change and filter replacement may help if the oil system is the issue.
10. How can I prevent the P103F code from recurring?
Regular maintenance, including timely oil changes and inspections of the electrical system, can help prevent this code from recurring.
