Code P2407 Dodge Description
The P2407 diagnostic trouble code for Dodge vehicles relates to the Evaporative Emission System Leak Detection Pump Sense Circuit being intermittent or erratic. The evaporative emission system is responsible for controlling the release of fuel vapor from the vehicle's fuel system, preventing it from escaping into the atmosphere. The leak detection pump (LDP) is a crucial component of this system, as it detects leaks in the system by monitoring the pressure.
Common Causes of P2407 Dodge
- Faulty Leak Detection Pump: The most common cause of the P2407 code is a malfunctioning or failed leak detection pump.
- Wiring Issues: Damaged or corroded wiring in the Evaporative Emission System Leak Detection Pump Sense Circuit can lead to intermittent or erratic signals.
- Vacuum Leaks: Any leaks in the vacuum lines connected to the evaporative emission system can disrupt the proper operation of the system.
- Faulty Purge Valve: A malfunctioning purge valve can cause pressure issues within the evaporative emission system, triggering the P2407 code.
Symptoms of P2407 Dodge
- Check Engine Light: The most common symptom associated with the P2407 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning evaporative emission system can result in reduced fuel efficiency, leading to more frequent trips to the gas station.
- Rough Idle: The vehicle may experience rough idling or hesitation when accelerating due to the improper operation of the evaporative emission system.
- Strong Fuel Smell: A noticeable fuel smell inside or outside the vehicle can indicate a potential leak in the system.
How to Fix P2407 Dodge
- Diagnose the Issue: Use a scan tool to retrieve the P2407 code and perform a visual inspection of the evaporative emission system components.
- Test the Leak Detection Pump: Check the operation of the leak detection pump to determine if it is functioning correctly.
- Inspect Wiring: Check the wiring in the Evaporative Emission System Leak Detection Pump Sense Circuit for any damage or corrosion, and repair or replace as needed.
- Check Vacuum Lines: Inspect the vacuum lines for any leaks or damage, and repair or replace as necessary.
- Replace Faulty Components: If the issue persists, replace any faulty components such as the leak detection pump or purge valve to resolve the P2407 code.
Cost to Fix P2407 Dodge
The typical repair costs for addressing the P2407 code can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It is recommended to check with local auto repair shops for a more accurate estimate of the repair costs. Keep in mind that rates may be higher at dealerships or in metropolitan areas, while independent shops often charge lower rates for repairs.

Frequently Asked Questions about P2407 Dodge Code
1. What does the OBDII code P2407 mean on a Dodge vehicle?
P2407 indicates an issue with the Evaporative Emission System Leak Detection Pump sense circuit, specifically that its signal is intermittent or erratic.
2. What are the common symptoms of code P2407 in a Dodge?
Symptoms may include an illuminated check engine light, failed emissions tests, decreased fuel efficiency, or a faint fuel odor near the vehicle.
3. What causes the P2407 code to appear on a Dodge?
Common causes include a faulty leak detection pump, damaged or corroded wiring or connectors in the circuit, a malfunctioning EVAP pressure sensor, or a failing control module.
4. Can I drive my Dodge with the P2407 code?
While the vehicle may still be driveable, ignoring the code could lead to increased emissions, reduced fuel efficiency, or further damage to the EVAP system.
5. How is the P2407 code diagnosed in a Dodge?
A technician will typically use a scan tool to confirm the code, inspect the leak detection pump and wiring, check for vacuum leaks, and test the EVAP system's functionality.
6. How do you fix the P2407 code on a Dodge vehicle?
Repairs may include replacing the leak detection pump, repairing or replacing damaged wiring or connectors, or addressing issues with the EVAP pressure sensor.
7. How much does it cost to fix the P2407 code on a Dodge?
The repair cost varies but typically ranges between $150 and $500, depending on whether the leak detection pump or other components need replacement.
8. What tools are needed to fix the P2407 code?
Common tools include a diagnostic scan tool, multimeter for testing electrical circuits, and potentially a smoke machine to check for EVAP leaks.
9. Can a loose gas cap cause the P2407 code on a Dodge?
While a loose gas cap is a common EVAP system issue, it typically triggers different codes like P0457 or P0456, not P2407.
10. How can I prevent the P2407 code from occurring again?
Regularly inspect and maintain your EVAP system components, ensure electrical connections are clean and secure, and address any fuel system issues promptly.
