Code P103E Jeep 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.
What are the Possible Causes of the DTC P103E Jeep?
- 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 P103E Jeep Code
What does the OBDII code P103E mean on a Jeep?
P103E indicates an open circuit in the Cylinder 4 Oil Supply Solenoid Valve Driver, which controls oil flow to the cylinder for proper engine operation.
What are the symptoms of a P103E code on a Jeep?
Symptoms may include poor engine performance, rough idling, reduced fuel efficiency, and the check engine light being illuminated.
What causes a P103E code to appear on a Jeep?
Common causes include a damaged or disconnected wiring harness, a faulty oil supply solenoid valve, or a malfunctioning engine control module (ECM).
Can I drive my Jeep with a P103E code?
Driving with a P103E code is not recommended, as it can lead to further engine damage or performance issues if left unresolved.
How do I fix the P103E code on my Jeep?
Inspect the wiring and connectors for damage, test the oil supply solenoid valve for proper operation, and replace any faulty components as needed.
How do I test the Cylinder 4 Oil Supply Solenoid Valve?
Use a multimeter to check for proper resistance in the solenoid valve and ensure it receives the correct voltage from the ECM.
Could a low oil level cause the P103E code?
Low oil levels are unlikely to directly cause this code but can contribute to solenoid valve malfunctions if oil flow is restricted.
Can a faulty ECM cause the P103E code?
Yes, a malfunctioning ECM can fail to send the correct signals to the solenoid valve, triggering the P103E code.
How much does it typically cost to fix a P103E code on a Jeep?
Repair costs vary but may range from $100 to $500, depending on whether the issue lies in wiring, the solenoid valve, or other components.
Do I need a professional mechanic to fix the P103E code?
While some basic checks like inspecting wiring can be done at home, diagnosing and repairing solenoid or ECM issues may require professional expertise.
