P103D Dodge Code - Cylinder 3 Oil Supply Solenoid Valve Driver Short To Ground
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 P103D 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 ground in the Solenoid Signal or Return circuit.
What are the Possible Causes of the DTC P103D Dodge?
- Faulty Variable Valve Actuator (VVA) Solenoid
- Variable Valve Actuator Solenoid harness is open or shorted
- Variable Valve Actuator Solenoid circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P103D Dodge?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P103D Dodge code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P103D Dodge Code
1. What does the OBDII code P103D mean for a Dodge vehicle?
P103D indicates a short-to-ground issue in the oil supply solenoid valve driver for cylinder 3, which controls oil flow for the cylinder's variable valve timing system.
2. What are the common symptoms of the P103D code?
Symptoms may include poor engine performance, rough idling, reduced fuel efficiency, an illuminated check engine light, and potential engine ticking noises.
3. What causes the P103D code to appear?
Common causes include damaged wiring or connectors, a faulty oil supply solenoid valve, a short circuit in the harness, or a malfunctioning powertrain control module (PCM).
4. Can driving with the P103D code damage the engine?
Yes, prolonged driving with this code can affect variable valve timing, leading to performance issues and potential long-term engine damage if not resolved.
5. How can I diagnose the P103D code?
Start by inspecting the wiring and connectors for cylinder 3's oil supply solenoid valve, check for shorts to ground, and test the solenoid's functionality with a multimeter.
6. How do I fix the P103D code on my Dodge vehicle?
Repairs may include replacing damaged wiring or connectors, installing a new oil supply solenoid valve for cylinder 3, or reprogramming or replacing the PCM if necessary.
7. What tools are needed to troubleshoot the P103D code?
A scan tool or OBDII scanner, a multimeter for testing electrical connections, and basic hand tools for removing and replacing components are typically required.
8. Is the oil supply solenoid valve for cylinder 3 expensive to replace?
The cost can vary depending on the make and model, but the solenoid itself is generally affordable, with higher costs coming from labor if done by a professional.
9. Can low oil levels cause the P103D code to appear?
While low oil levels do not directly cause a short-to-ground issue, insufficient oil can lead to solenoid malfunctions, which might trigger related codes.
10. Should I clear the P103D code after repairs?
Yes, after completing repairs, clear the code using an OBDII scanner and test-drive the vehicle to ensure the issue is resolved and the code does not return.
