P240B Meaning

The engine control module (ECM) monitors the power consumption of the leak detection pump. This diagnostic trouble code (DTC) can be diagnosed when the leak diagnostic system is running. A DTC is stored if the actual current consumption of the pump in the leak detection pump unit varies too much during the reference phase.

The code P2413 is related to the EGR (Exhaust Gas Recirculation) system, specifically to an issue of insufficient performance of the EGR system. This can affect emissions and lead to reduced engine energy efficiency.

Possible Symptoms:

• Reduced Energy Efficiency: Engine performance may be affected, reducing fuel efficiency.
• Presence of Other Related EGR Codes: Error codes related to other EGR components or sensors.
• Check Engine Light: The warning light illuminates to indicate a problem with the EGR system.
• Presence of a Stored Code: The P2413 code is stored in the Engine Control Module (ECM).

Possible Causes of Code P2413:

1. Faulty EGR Sensor: The sensor monitoring the EGR system’s operation may be defective, sending an incorrect signal to the control module.
2. Faulty MAP/MAT Sensor: The Manifold Absolute Pressure (MAP) or Manifold Air Temperature (MAT) sensors may be defective, affecting the EGR system.
3. Faulty EGR Valve: The EGR valve may be defective or stuck, preventing the system from functioning properly.
4. Exhaust Leaks: Leaks in the exhaust system can disrupt gas flow and affect EGR system performance.
5. Cracked or Collapsed Vacuum Lines: The vacuum lines used to control the EGR valve may be damaged, affecting its operation.
6. Open or Shorted EGR Control or Monitoring Circuits: Issues in the wiring or electrical connections can disrupt EGR valve control.

Diagnostic and Repair Procedures:

1. Initial Check:
   • Visual Inspection: Start by inspecting the EGR system’s wiring and connectors for damage or corrosion.
   • Diagnostic Scanner: Use a scanner to retrieve all associated error codes. Clear the codes and test the vehicle again to see if P2413 returns.
2. EGR Valve Tests:
   • Hand Vacuum Pump: If the vehicle uses a vacuum-operated diaphragm EGR valve, connect the vacuum pump to the EGR valve and observe scanner data. Activating the vacuum pump should cause the engine to stall if the valve is functioning correctly.
   • EGR Passage Inspection: If the valve appears functional but the engine does not stall with the vacuum pump, the EGR passages may be clogged. Clean the passages if necessary.
3. Sensor and Valve Verification:
   • Test the EGR valve’s resistance using a multimeter to ensure it meets manufacturer specifications.
   • If the EGR valve is linear, use a scanner to actuate the valve and verify its proper operation.
4. Repair and Replacement:
   • If the EGR valve or sensors are faulty, replace them. Clogged EGR passages can usually be cleaned, while EGR valves and sensors should be replaced if necessary.

Additional Diagnostic Notes:

• EGR valve failure is less common than clogged passages or faulty sensors.
• EGR systems designed to supply gases to individual cylinders can cause misfires if the passages are blocked.

Conclusion:

The P2413 code indicates a problem with the EGR system’s performance. By following the diagnostic steps, you can determine whether the issue stems from the EGR valve, associated sensors, vacuum lines, or clogged passages. Repairing the code typically involves cleaning the EGR passages or replacing the faulty valve or sensors.
