P2426 Dodge Code - Exhaust Gas Recirculation Cooling Valve Control Circuit Low
Quick Answer
The P2426 diagnostic trouble code (DTC) for Dodge vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) Cooling Valve Control Circuit being too low. Common causes include Faulty EGR Cooling Valve: The valve itself may be malfunctioning and not responding to control signals properly, Wiring or Connector Damage: Corrosion, fraying, or loose connections in the wiring harness or connectors can disrupt the control circuit, ECM Malfunction: Issues with the Engine Control Module responsible for regulating the EGR system can lead to control circuit errors. 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 P2426 Dodge Description
The P2426 diagnostic trouble code (DTC) for Dodge vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) Cooling Valve Control Circuit being too low. The EGR system in a vehicle is responsible for reducing nitrogen oxide emissions by recirculating a portion of the exhaust gases back into the engine's combustion chambers. The EGR cooling valve is an essential component of this system as it helps regulate the temperature of the exhaust gases before they are reintroduced into the engine.
Common Causes of P2426 Dodge
- Faulty EGR Cooling Valve: The valve itself may be malfunctioning and not responding to control signals properly.
- Wiring or Connector Damage: Corrosion, fraying, or loose connections in the wiring harness or connectors can disrupt the control circuit.
- ECM Malfunction: Issues with the Engine Control Module responsible for regulating the EGR system can lead to control circuit errors.
- Vacuum Leaks: Any leaks in the vacuum lines connected to the EGR system can affect the valve's operation.
- Carbon Buildup: Accumulation of carbon deposits in the EGR system can hinder the valve's movement and cause control circuit issues.
Symptoms of P2426 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.
- Reduced Fuel Efficiency: A decrease in fuel efficiency due to improper recirculation of exhaust gases can be observed.
- Rough Idling: The engine may experience rough idling or hesitation during acceleration.
- Increased Emissions: The vehicle may fail emissions tests or emit higher levels of pollutants.
- Engine Performance Issues: The engine may lack power or responsiveness, impacting overall driving experience.
How to Fix P2426 Dodge
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the EGR cooling valve, wiring, connectors, and ECM.
- Replace EGR Cooling Valve: If the valve is found to be faulty, replace it with a new one according to the manufacturer's specifications.
- Repair Wiring or Connectors: Repair or replace any damaged wiring or connectors in the control circuit to ensure proper connection.
- Check ECM Functionality: Verify the ECM's functionality and reprogram or replace it if necessary to address control circuit errors.
- Clear DTCs and Test Drive: Clear the DTCs from the vehicle's memory, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2426 Dodge
The cost of repairing the P2426 code for a Dodge vehicle can vary depending on the specific model, location, and labor rates.

Frequently Asked Questions about P2426 Dodge Code
1. What does the OBDII code P2426 mean on a Dodge?
P2426 indicates a low voltage issue in the Exhaust Gas Recirculation (EGR) Cooling Valve Control Circuit, which helps regulate exhaust gas temperatures and emissions.
2. What are the common symptoms of the P2426 code on a Dodge vehicle?
Symptoms may include an illuminated check engine light, reduced engine performance, increased emissions, or overheating of the EGR system.
3. What causes the P2426 code on a Dodge?
Common causes include a faulty EGR cooling valve, damaged wiring or connectors in the control circuit, or a malfunctioning powertrain control module (PCM).
4. Can a dirty EGR cooling valve trigger the P2426 code?
Yes, a dirty or clogged EGR cooling valve can restrict movement and lead to low voltage signals, triggering the P2426 code.
5. How can I diagnose the P2426 code on my Dodge?
Start by checking the EGR cooling valve, inspecting wiring and connectors for damage, and testing the control circuit with a multimeter to ensure proper voltage.
6. Is it safe to drive with the P2426 code on a Dodge?
Driving with this code is not recommended as it may lead to increased emissions, engine overheating, or damage to the EGR system.
7. How do I fix the P2426 code on my Dodge?
Repairs may include replacing the EGR cooling valve, repairing damaged wiring or connectors, or reprogramming or replacing the PCM if necessary.
8. How much does it cost to repair the P2426 code on a Dodge?
Repair costs can range from $150 to $600, depending on whether the EGR cooling valve or wiring needs replacement and labor rates in your area.
9. Can a bad PCM cause the P2426 code on a Dodge?
Yes, a faulty PCM can fail to properly control the EGR cooling valve, resulting in the P2426 code.
10. Will clearing the P2426 code with a scanner fix the problem?
Clearing the code will reset the check engine light temporarily, but the underlying issue must be addressed to prevent the code from returning.
