Code P103C Chrysler 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.

- 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)

Frequently Asked Questions about P103C Chrysler Code
What does the OBDII code P103C mean for a Chrysler vehicle?
P103C indicates a problem with the Cylinder 3 Oil Supply Solenoid Valve Driver circuit, specifically a short to the battery.
What are the common symptoms of the P103C code?
Symptoms may include an illuminated check engine light, poor engine performance, rough idling, and possible misfires in Cylinder 3.
What causes the P103C code to appear?
Common causes include damaged wiring, a short in the solenoid valve driver circuit, a faulty oil supply solenoid valve, or a malfunctioning engine control module (ECM).
Can I drive my Chrysler with the P103C code?
Driving with this code is not recommended, as it can lead to poor engine performance and potential damage to internal components if the issue is not addressed.
How can I diagnose the P103C code?
Start by inspecting the wiring and connectors for damage or corrosion, test the solenoid valve for proper operation, and check for shorts or voltage irregularities in the circuit.
What tools are needed to troubleshoot the P103C code?
You’ll need an OBDII scan tool, a multimeter, and possibly a wiring diagram for your Chrysler model to diagnose the issue effectively.
How do you fix the P103C code?
Repairs may involve replacing damaged wiring, repairing shorts, replacing the Cylinder 3 Oil Supply Solenoid Valve, or reprogramming or replacing the ECM.
What is the cost to fix the P103C code?
Repair costs vary widely depending on the cause, ranging from $50 for simple wiring repairs to $500 or more if the ECM or solenoid valve needs replacement.
Can a bad oil supply solenoid valve cause engine damage?
Yes, if the solenoid valve fails to regulate oil flow properly, it can lead to poor lubrication or engine performance issues over time.
How can I prevent the P103C code from reoccurring?
Regularly inspect and maintain your vehicle’s wiring and connectors, and ensure timely oil changes to prevent solenoid valve clogging or failure.
