P2413 - EXHAUST GAS RECIRCULATION SYSTEM PERFORMANCE

POST UPDATED IN November, 2021

Description of DTC code P2413 Generic

The DTC P2413 OBD2 code setting implies that the Powertrain Control Module (PCM) has encountered a malfunction in the Exhaust Gas Recirculation (EGR) system.

The EGR system is designed to reduce nitrogen oxide in the engine exhaust. This system has a valve that is electronically controlled by a voltage signal from the PCM. This signal indicates when the valve should open, allowing part of the exhaust gases to return to the engine’s induction system. In this place, the excess nitrogen oxide vapors are burned.

The EGR system valve uses an electronically controlled solenoid to divert the intake vacuum to the valve. The solenoid is commanded by the PCM to allow the vacuum to pass through and reach the EGR valve. To accomplish this, it opens the valve to the desired degree. When the PCM commands the EGR valve to open and does not observe the expected degree of change, this code is stored.

Symptoms of fault code P2413 Generic

  • The Check Engine light turns on.
  • Lower fuel efficiency.
  • Other EGR system codes are stored.

Causes of OBD2 P2413 Generic

Reasons for setting the P2413 OBDII fault code:

Possible solutions of the DTC code P2413 Generic

To troubleshoot the P2413 OBD2 diagnostic code, try this:

  • For a good diagnosis, it is recommended to review the Technical Service Bulletins.
  • Check all the cables and connectors that are related to the system. If any of these have deficiencies that could cause an open or short circuit, repair or replace these components.
  • Connect a scanner to the diagnostic port, and a hose from the manual vacuum pump to the EGR vacuum port. Start the engine and let it idle, and observe the necessary data displayed by the scanner while slowly triggering the vacuum pump. You should observe an engine stall due to excessive EGR activation at idle. If the engine does not stop when the vacuum pump is depressed, possibly the EGR valve is defective, or there are blockages in the EGR Clean the system passages, and check the EGR valve for good condition. Replace it if necessary.
  • If the valve of your vehicle's EGR system is linear, you should actuate it with the scanner and test the resistance of the valve with a DVOM. If the valve values obtained are within specifications, perform continuity and resistance tests on the associated circuit. Repair if necessary.
