Code P1066 Chrysler Description
The P1066 Chrysler code indicates that the Cylinder 1 Oil Supply Solenoid Valve Switch OFF Time is out of range. This means that there is an issue with the solenoid valve in the oil supply system for cylinder 1, which controls the flow of oil to the cylinder. The oil supply solenoid valve plays a crucial role in ensuring that the engine receives the proper amount of oil for lubrication and cooling. When the switch-off time is out of range, it can lead to inadequate oil supply to the cylinder, resulting in poor engine performance, increased wear and tear on engine components, and potential long-term damage if not addressed promptly.
Common Causes of P1066 Chrysler
- Faulty Oil Supply Solenoid Valve: The most common cause of the P1066 code is a malfunctioning oil supply solenoid valve that is stuck open, closed, or intermittent.
- Wiring Issues: Electrical problems such as corroded or damaged wiring harnesses, connectors, or terminals can disrupt the communication between the ECM and the solenoid valve.
- ECM Malfunction: A faulty engine control module (ECM) can send incorrect signals to the oil supply solenoid valve, causing it to operate out of range.
- Low Oil Level: Insufficient oil in the engine can also trigger the P1066 code, as the solenoid valve may struggle to maintain proper oil pressure.
- Engine Wear: Wear and tear on engine components, such as the solenoid valve itself or other related parts, can lead to malfunctions that trigger the code.
Symptoms of P1066 Chrysler
- Check Engine Light: The most common symptom associated with the P1066 code is the illumination of the check engine light on the dashboard.
- Engine Misfires: A malfunctioning oil supply solenoid valve can lead to engine misfires, rough idling, and hesitation during acceleration.
- Decreased Engine Performance: Insufficient oil supply to the cylinder can result in decreased engine performance, reduced power output, and poor fuel efficiency.
- Engine Overheating: In severe cases, inadequate oil supply can cause the engine to overheat, leading to potential engine damage and failure.
- Engine Knocking: A lack of proper lubrication due to the malfunctioning solenoid valve can result in engine knocking or tapping noises.
How to Fix P1066 Chrysler
- Diagnose the Issue: Begin by using a scan tool to retrieve the fault code and perform a thorough inspection of the oil supply solenoid valve, wiring, and ECM.
- Replace Oil Supply Solenoid Valve: If the solenoid valve is found to be faulty, replace it with a new OEM part to ensure proper operation.
- Repair Wiring: Inspect the wiring harness, connectors, and terminals for any damage or corrosion, and repair or replace as needed to restore proper electrical connections.
- Reset ECM: Clear the fault code from the ECM memory using a scan tool and reset the system to see if the code returns after repairs are completed.
- Perform Test Drive: After the repair process is complete, take the vehicle for a test drive to ensure that the issue has been resolved and that the check engine light remains off.
Cost to Fix P1066 Chrysler
The typical repair costs for addressing the P1066 Chrysler code can vary depending on the extent of the issue, the cost of parts, and labor rates at auto repair shops. As a rough estimate, the cost of replacing the oil supply solenoid valve and addressing any wiring issues can range from $200 to $500. However, it's essential to consider that diagnosis time and labor rates at auto repair shops can vary significantly based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher at dealerships or in metropolitan areas. It's advisable to check with local shops for a more accurate estimate of repair costs.

Frequently Asked Questions about P1066 Chrysler Code
1. What does the OBDII code P1066 mean for a Chrysler vehicle?
The P1066 code in a Chrysler indicates that the Cylinder 1 Oil Supply Solenoid Valve has been switched off for longer than the expected time frame, suggesting an issue with the valve's operation or control circuit.
2. What are common symptoms of code P1066 in Chrysler?
Symptoms include the engine light turning on, possible engine roughness, reduced fuel efficiency, and in some cases, the engine might experience difficulty in starting or poor performance.
3. What can cause the P1066 code to appear in a Chrysler?
Causes for the P1066 code can include a faulty Cylinder 1 Oil Supply Solenoid, blockages in the oil passages, issues with the solenoid control circuit (like damaged wires or poor connections), or a malfunctioning Engine Control Module (ECM).
4. How is the P1066 code diagnosed in a Chrysler?
Diagnosis involves using a scan tool to confirm the presence of the P1066 code, visually inspecting the solenoid and wiring for damage, checking the oil passages for blockages, and potentially testing the solenoid and ECM function with advanced diagnostic tools.
5. What repairs can fix the P1066 code in a Chrysler?
Repairs might include replacing the Cylinder 1 Oil Supply Solenoid, cleaning or removing blockages in the oil passages, repairing or replacing damaged wiring or connectors, and in some cases, replacing the ECM.
