P2143 Dodge Code - Exhaust Gas Recirculation Vent Control Circuit/Open
Quick Answer
The P2143 code for Dodge vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) vent control circuit, specifically an open circuit. Common causes include Faulty EGR Vent Control Solenoid: The EGR vent control solenoid may be defective, causing the circuit to remain open, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness related to the EGR vent control circuit can lead to an open circuit, EGR Valve Failure: A malfunctioning EGR valve can also trigger this code if it is unable to open or close properly. 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 P2143 Dodge Description
The P2143 code for Dodge vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) vent control circuit, specifically an open circuit. The EGR system is responsible for recirculating a portion of the engine's exhaust gas back into the intake manifold to reduce nitrogen oxide emissions. The EGR vent control circuit controls the opening and closing of the EGR valve, allowing the correct amount of exhaust gas to enter the intake system.
Common Causes of P2143 Dodge
- Faulty EGR Vent Control Solenoid: The EGR vent control solenoid may be defective, causing the circuit to remain open.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness related to the EGR vent control circuit can lead to an open circuit.
- EGR Valve Failure: A malfunctioning EGR valve can also trigger this code if it is unable to open or close properly.
- ECM/PCM Malfunction: A problem with the Engine Control Module (ECM) or Powertrain Control Module (PCM) can also cause issues with the EGR system.
- Vacuum Leaks: Any vacuum leaks in the EGR system can disrupt the proper functioning of the EGR valve and vent control circuit.
Symptoms of P2143 Dodge
- 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 Idling: The engine may experience rough idling or stalling due to improper EGR valve operation.
- Decreased Fuel Efficiency: A faulty EGR vent control circuit can lead to decreased fuel efficiency as the engine may not be operating at optimal conditions.
- Increased Emissions: The vehicle may fail emissions testing or produce higher levels of harmful emissions due to the malfunctioning EGR system.
How to Fix P2143 Dodge
- Diagnose the Issue: Use a scan tool to retrieve the fault code and perform a visual inspection of the EGR system components and wiring.
- Test EGR Vent Control Solenoid: Test the EGR vent control solenoid for proper operation and replace if necessary.
- Check Wiring: Inspect the wiring harness for damage, corrosion, or loose connections and repair or replace as needed.
- Test EGR Valve: Test the EGR valve to ensure it is opening and closing correctly, replacing it if faulty.
- Clear Codes and Test Drive: Clear the fault codes after repairs are made and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2143 Dodge
The cost to repair a P2143 code for Dodge vehicles can vary depending on the specific cause of the issue and the labor rates at the auto repair shop.
