P1046 Chrysler Code - Cylinder 1 Oil Supply Solenoid Valve Overcurrent
Quick Answer
The P1046 Chrysler diagnostic trouble code (DTC) indicates a problem with the Cylinder 1 Oil Supply Solenoid Valve Overcurrent. Common causes include Faulty Oil Supply Solenoid Valve: A malfunctioning solenoid valve can result in overcurrent conditions, triggering the P1046 code, Wiring or Connector Issues: Damaged or corroded wiring or connectors in the oil supply solenoid valve circuit can disrupt the electrical flow, leading to overcurrent, Engine Control Module (ECM) Malfunction: A malfunctioning ECM can send incorrect signals to the oil supply solenoid valve, causing overcurrent issues. 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 P1046 Chrysler Description
The P1046 Chrysler diagnostic trouble code (DTC) indicates a problem with the Cylinder 1 Oil Supply Solenoid Valve Overcurrent. This code is specific to Chrysler vehicles and is related to the engine's oil supply system. The oil supply solenoid valve is responsible for controlling the flow of oil to the cylinder head, ensuring proper lubrication of the engine components. When the solenoid valve experiences overcurrent, it means that there is an excessive amount of electrical current flowing through the valve, which can lead to various issues within the engine.
Common Causes of P1046 Chrysler
- Faulty Oil Supply Solenoid Valve: A malfunctioning solenoid valve can result in overcurrent conditions, triggering the P1046 code.
- Wiring or Connector Issues: Damaged or corroded wiring or connectors in the oil supply solenoid valve circuit can disrupt the electrical flow, leading to overcurrent.
- Engine Control Module (ECM) Malfunction: A malfunctioning ECM can send incorrect signals to the oil supply solenoid valve, causing overcurrent issues.
- Low Oil Level: Insufficient oil in the engine can also contribute to overcurrent conditions, as the valve may work harder to maintain proper lubrication.
- Electrical Short: An electrical short in the circuit can cause excessive current flow through the solenoid valve, triggering the code.
Symptoms of P1046 Chrysler
- Check Engine Light: The most common symptom associated with the P1046 code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: If the oil supply to the cylinder head is compromised, it can result in a rough or uneven idle when the engine is running.
- Decreased Engine Performance: A lack of proper lubrication can lead to decreased engine performance, including reduced power output and acceleration.
- Engine Misfires: Insufficient oil supply can cause engine misfires, resulting in a noticeable loss of smooth operation and potential stalling.
- Increased Fuel Consumption: When engine components are not adequately lubricated, the engine may consume more fuel to compensate for the decreased efficiency.
How to Fix P1046 Chrysler
- Diagnose the Issue: Use a diagnostic scanner to retrieve the DTC and perform a thorough inspection of the oil supply solenoid valve, wiring, and connectors to identify the root cause of the overcurrent condition.
- Replace the Oil Supply Solenoid Valve: If the valve is found to be faulty, replace it with a new, OEM-approved part to ensure proper operation.
- Repair Wiring or Connectors: If damaged wiring or connectors are the culprit, repair or replace them as needed to restore proper electrical flow.
- Check Oil Level: Verify that the engine oil level is adequate and top up if necessary to prevent future overcurrent issues.
- Clear DTC and Test Drive: Clear the DTC from the ECM memory using the diagnostic scanner and perform a test drive to ensure that the issue has been resolved.
Cost to Fix P1046 Chrysler
The typical repair costs for addressing the P1046 Chrysler code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. On average, the parts cost for a new oil supply solenoid valve can range from $100 to $200, while the labor cost for diagnosis and repair can be around $150 to $300. Overall, the total repair costs for this issue may range from $250 to $500, but it's essential to obtain a detailed quote from a trusted auto repair shop to get an accurate estimate based on your vehicle's make and model. Keep in mind that rates can vary based on location, the complexity of the repair, and the shop's hourly labor rates.
