Code P1066 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 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 measures the time needed to turn on the VVA Solenoid. When the PCM recognizes that the VVA Solenoids switch off time is too fast or too slow a fault is set.
What are the Possible Causes of the DTC P1066 Chrysler?
- Engine oil level low
- Engine oil contaminated
- Incorrect oil filter
- Insufficient oil pressure due to a mechanical failure in the oiling system
- Faulty Variable Valve Actuator (VVA) Assembly

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.
6. Is it safe to drive a Chrysler with the P1066 code?
While you might be able to drive with this code active, it is advisable to address the issue as soon as possible to avoid potential engine damage or performance issues that could compromise vehicle safety.
7. What is the role of the Cylinder 1 Oil Supply Solenoid in a Chrysler?
The Cylinder 1 Oil Supply Solenoid controls the flow of oil to the engine's first cylinder to ensure optimal lubrication and cooling under different operating conditions, playing a critical role in engine performance and health.
8. How urgent is it to fix a P1066 code in a Chrysler?
Addressing a P1066 code should be considered urgent, as prolonged issues with oil supply can lead to engine damage, which can be costly and more complex to repair if not dealt with promptly.
9. Can a faulty oil filter or low oil levels trigger a P1066 code in a Chrysler?
While a faulty oil filter or low oil levels primarily cause other issues, they can indirectly contribute to this code by affecting overall oil pressure and flow, which may impact the performance of the oil supply solenoid.
