Code P104A 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 Variable Valve Actuator (VVA) solenoid current feedback level in voltage is out of range.

Frequently Asked Questions about P104A Chrysler Code
1. What does the OBDII code P104A mean for a Chrysler vehicle?
P104A indicates an overcurrent condition in the Cylinder 3 Oil Supply Solenoid Valve, which may affect engine performance and oil flow control.
2. What are the common symptoms of the P104A code?
Symptoms may include reduced engine performance, unusual noises from the engine, poor fuel efficiency, or the Check Engine Light illuminating.
3. What causes the P104A Cylinder 3 Oil Supply Solenoid Valve Overcurrent code?
Common causes include a faulty oil supply solenoid valve, damaged wiring or connectors, a short circuit, or issues with the engine control module (ECM).
4. Can I drive my vehicle with the P104A code active?
Driving with this code is not recommended as it can lead to improper oil flow and potential engine damage over time.
5. How do you diagnose the P104A code?
Diagnosis involves inspecting the solenoid valve, checking the wiring and connectors for damage, and using a multimeter to test for shorts or excessive current.
6. How do you fix the P104A code on a Chrysler?
Repairs may include replacing the Cylinder 3 Oil Supply Solenoid Valve, repairing damaged wiring, or updating/reprogramming the ECM if necessary.
7. How much does it cost to repair the P104A code?
Repair costs can vary, but replacing an oil supply solenoid valve typically ranges from $150 to $300, including labor.
8. Can the P104A code be caused by low engine oil?
Low oil levels are not a direct cause, but inadequate lubrication can exacerbate solenoid issues or trigger related problems.
9. Is the P104A code specific to Chrysler vehicles?
While P104A is most commonly associated with Chrysler vehicles, similar codes may appear in other manufacturers with comparable systems.
10. What happens if the P104A code is ignored?
Ignoring this code can lead to engine performance issues, increased wear on internal components, and potentially costly engine damage.
