P1655 Saturn Code - EVAP Purge Solenoid Control Circuit
Quick Answer
The P1655 Saturn code refers to an issue with the EVAP (Evaporative Emission Control System) Purge Solenoid Control Circuit. Common causes include Faulty Purge Solenoid: The purge solenoid itself may be defective, causing the control circuit to malfunction, Wiring Issues: Damage to the wiring or connectors in the EVAP purge solenoid control circuit can prevent proper communication between the solenoid and the vehicle's ECM (Engine Control Module), Vacuum Leaks: Any leaks in the vacuum lines connected to the EVAP system can disrupt the system's operation. 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 P1655 Saturn Description
The P1655 Saturn code refers to an issue with the EVAP (Evaporative Emission Control System) Purge Solenoid Control Circuit. The EVAP system is designed to capture and store fuel vapors from the fuel tank to prevent them from being released into the atmosphere. The purge solenoid is responsible for controlling the flow of fuel vapors from the charcoal canister to the engine intake manifold.
Common Causes of P1655 Saturn
- Faulty Purge Solenoid: The purge solenoid itself may be defective, causing the control circuit to malfunction.
- Wiring Issues: Damage to the wiring or connectors in the EVAP purge solenoid control circuit can prevent proper communication between the solenoid and the vehicle's ECM (Engine Control Module).
- Vacuum Leaks: Any leaks in the vacuum lines connected to the EVAP system can disrupt the system's operation.
- ECM Failure: A malfunction in the ECM, which controls the EVAP system, can also trigger this code.
Symptoms of P1655 Saturn
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Rough Idle: A malfunctioning EVAP purge solenoid control circuit can cause the engine to idle roughly or stall.
- Decreased Fuel Efficiency: A faulty EVAP system can lead to increased fuel consumption due to the improper handling of fuel vapors.
- Strong Fuel Odor: If the EVAP system is not functioning properly, you may notice a strong smell of fuel around the vehicle.
How to Fix P1655 Saturn
- Diagnostic Testing: The first step in resolving this issue is to perform diagnostic testing to confirm that the EVAP purge solenoid control circuit is indeed the problem.
- Inspect Wiring and Connections: Check the wiring and connectors in the EVAP purge solenoid control circuit for any damage or corrosion. Repair or replace as needed.
- Test Purge Solenoid: Test the purge solenoid to ensure it is functioning properly. Replace if necessary.
- Check Vacuum Lines: Inspect the vacuum lines connected to the EVAP system for any leaks or damage. Repair or replace as needed.
- Clear Codes: Once the issue has been resolved, clear the diagnostic trouble codes and reset the Check Engine Light.
Cost to Fix P1655 Saturn
The typical repair costs for addressing a P1655 Saturn code can vary depending on the specific cause of the issue. In general, the cost of parts for replacing a faulty purge solenoid or repairing wiring/connectors can range from $50 to $200. Labor costs can add another $100 to $300 to the total repair bill. Overall, you can expect to pay anywhere from $150 to $500 for resolving this issue. However, it's important to note that labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate cost estimate based on your location and vehicle model.
