P1140 Chrysler Code - Vacuum Reservoir Solenoid Circuit Condition
Quick Answer
The P1140 Chrysler code indicates a problem with the vacuum reservoir solenoid circuit in the vehicle. Common causes include Faulty Solenoid: The vacuum reservoir solenoid itself may be defective and in need of replacement, Wiring Issues: Damage to the wiring harness or connectors associated with the solenoid circuit can disrupt the flow of electricity and cause the code to trigger, Vacuum Leak: A leak in the vacuum system can prevent the proper operation of the solenoid, leading to the P1140 code. 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 P1140 Chrysler Description
The P1140 Chrysler code indicates a problem with the vacuum reservoir solenoid circuit in the vehicle. The vacuum reservoir solenoid is responsible for controlling the flow of vacuum to various components in the vehicle, such as the EGR (Exhaust Gas Recirculation) valve and the EVAP (Evaporative Emission Control) system. When this circuit condition is not functioning properly, it can lead to a variety of issues that can affect the vehicle's performance and emissions.
Common Causes of P1140 Chrysler
- Faulty Solenoid: The vacuum reservoir solenoid itself may be defective and in need of replacement.
- Wiring Issues: Damage to the wiring harness or connectors associated with the solenoid circuit can disrupt the flow of electricity and cause the code to trigger.
- Vacuum Leak: A leak in the vacuum system can prevent the proper operation of the solenoid, leading to the P1140 code.
- ECM (Engine Control Module) Malfunction: A malfunction in the ECM can also trigger this code by sending incorrect signals to the solenoid.
Symptoms of P1140 Chrysler
- Check Engine Light: The most common symptom associated with the P1140 code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Engine Performance: The vehicle may experience rough idling, hesitation, or a lack of power when accelerating.
- Decreased Fuel Efficiency: A faulty vacuum reservoir solenoid circuit can lead to decreased fuel efficiency, causing the vehicle to consume more fuel than usual.
- Emissions Issues: The vehicle may fail emissions tests or emit higher levels of pollutants due to the malfunctioning circuit.
How to Fix P1140 Chrysler
- Diagnose the Issue: Begin by using a diagnostic scanner to retrieve the fault code and identify the specific cause of the problem.
- Inspect Wiring and Connections: Check the wiring harness and connectors for any damage or corrosion, and repair or replace them as needed.
- Test the Vacuum Reservoir Solenoid: Test the solenoid itself to determine if it is functioning properly. Replace it if necessary.
- Check for Vacuum Leaks: Inspect the vacuum system for any leaks and repair them to ensure proper operation.
- Clear the Code: After completing the repairs, use the diagnostic scanner to clear the fault code and reset the check engine light.
Cost to Fix P1140 Chrysler
The typical repair costs for addressing the P1140 Chrysler code can vary depending on the specific cause of the issue and the parts and labor required for the repair. In general, the cost of replacing a faulty vacuum reservoir solenoid can range from $100 to $300, including parts and labor. However, if additional repairs are needed, such as fixing wiring issues or repairing vacuum leaks, the total cost can increase accordingly.
