Code P103A 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 ground 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 P103A Chrysler Code
1. What does the OBDII code P103A mean on a Chrysler?
P103A indicates a problem with the Cylinder 2 Oil Supply Solenoid Valve Driver, specifically a short to ground in the circuit.
2. What are the common symptoms of code P103A in a Chrysler?
Symptoms may include a check engine light, poor engine performance, rough idling, cylinder misfires, or decreased fuel efficiency.
3. What causes the P103A code to be triggered?
Common causes include damaged wiring, a short to ground in the solenoid circuit, a faulty oil supply solenoid, or issues with the powertrain control module (PCM).
4. Can I drive my Chrysler with a P103A code?
Driving with this code is not recommended as it may lead to engine performance issues and potential damage if the problem is not addressed.
5. How do I diagnose the P103A code on a Chrysler?
Diagnosis involves inspecting the solenoid wiring for damage, testing the solenoid for proper operation, and using a multimeter to check for a short to ground in the circuit.
6. How do I fix the P103A code on a Chrysler?
Repairs may include replacing damaged wiring, repairing the short to ground, replacing the oil supply solenoid, or in rare cases, reprogramming or replacing the PCM.
7. How much does it cost to repair a P103A code?
Costs vary depending on the issue, but replacing an oil supply solenoid typically costs between $100 and $300, plus labor.
8. Can a faulty PCM cause the P103A code?
Yes, a faulty PCM is a less common but possible cause of this code, especially if wiring and the solenoid are functioning correctly.
9. What tools are needed to diagnose the P103A code?
You'll need an OBDII scanner, a multimeter, and possibly wiring diagrams specific to your Chrysler model.
10. Will clearing the P103A code solve the issue permanently?
No, clearing the code will turn off the check engine light temporarily, but the underlying problem must be repaired to prevent the code from returning.
