P2144 Dodge Code - Exhaust Gas Recirculation Vent Control Circuit Low

Quick Answer

The P2144 diagnostic trouble code for Dodge vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) vent control circuit being low. Common causes include Faulty EGR Valve: A malfunctioning EGR valve can lead to issues with the vent control circuit, Wiring Issues: Damaged or corroded wiring connections related to the EGR vent control circuit can trigger this code, EGR Sensor Failure: A failed EGR sensor can also cause the circuit to register as low. 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 P2144 Dodge Description

The P2144 diagnostic trouble code for Dodge vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) vent control circuit being low. The EGR system is responsible for recirculating a portion of the exhaust gas back into the engine's intake system to reduce harmful emissions and improve fuel efficiency. The vent control circuit is a crucial component of the EGR system that regulates the flow of exhaust gas. When this circuit is detected to be low, it can lead to improper recirculation of exhaust gas, affecting the engine's performance and emissions.

Common Causes of P2144 Dodge

  1. Faulty EGR Valve: A malfunctioning EGR valve can lead to issues with the vent control circuit.
  2. Wiring Issues: Damaged or corroded wiring connections related to the EGR vent control circuit can trigger this code.
  3. EGR Sensor Failure: A failed EGR sensor can also cause the circuit to register as low.
  4. ECM Malfunction: An issue with the engine control module (ECM) could result in incorrect EGR system readings.

Symptoms of P2144 Dodge

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
  2. Rough Idle: A low EGR vent control circuit can cause the engine to idle roughly or inconsistently.
  3. Decreased Fuel Efficiency: The vehicle may experience a decrease in fuel efficiency due to improper exhaust gas recirculation.
  4. Engine Misfires: In severe cases, the engine may misfire or run erratically due to the disrupted EGR system operation.

How to Fix P2144 Dodge

  1. Diagnose the Issue: Use a diagnostic scan tool to identify the specific cause of the low EGR vent control circuit.
  2. Inspect Wiring: Check the wiring and connectors associated with the EGR system for any damage or corrosion.
  3. Test EGR Valve: Verify the functionality of the EGR valve and replace it if necessary.
  4. Replace EGR Sensor: If the EGR sensor is found to be faulty, replace it with a new one.
  5. Clear Codes: After performing the necessary repairs, clear the diagnostic trouble codes and test the vehicle to ensure the issue has been resolved.

Cost to Fix P2144 Dodge

The typical repair costs for addressing a P2144 code in a Dodge vehicle can vary depending on the specific cause of the issue and the required repairs. Generally, parts such as a new EGR valve or sensor can range from $100 to $300, while labor costs may total between $100 and $200. Overall, the total cost of resolving this issue can amount to approximately $200 to $500. It's important to note that the actual costs may differ based on the location, vehicle model, and labor rates at auto repair shops.
