Fault code P2413 is called “Exhaust Gas Recirculation (EGR) System Range/Performance” but in different programs it may be called differently. This fault designation applies to all vehicles equipped with OBD-II.

Technical description and explained code P2413

Diagnostic Trouble Code P2413 indicates a malfunction of the Exhaust Gas Recirculation (EGR) system. The exhaust gas recirculation system is designed to lower the combustion temperature, thereby reducing nitrogen oxide (NOx) emissions.

The system is based on an exhaust gas recirculation valve. A device that allows the exhaust gases to pass into the intake manifold and combine with the air-fuel mixture. From there, the mixture, which is diluted and cooled, moves into the engine combustion chamber, where it is burned.

Previously, many of the exhaust gas recirculation valves were vacuum operated. Nowadays, however, almost all of them are controlled electronically. Most electronic devices have a built-in solenoid (or stepping motor). That lifts a pin inside the exhaust recirculation valve from its seat. When the pin moves, exhaust gases can flow through the opening into the intake manifold.

The transmission control module (PCM), controls the operation of the EGR valve in an electronically controlled system. Sensors such as absolute manifold pressure (MAP), mass air flow (MAF), and coolant temperature (ECT). Transmit engine performance data to the PCM. The PCM then uses this information to determine when to open and close the exhaust gas recirculation valve.

Error P2413 indicates that the PCM has detected a problem with the exhaust gas recirculation system performance range mismatch. This means that the data sent to the control module is above or below the range of programmed parameters.

Symptoms of vehicle malfunctions

The main signal that an error P2413 has occurred is the Malfunction Indicator Lamp (MIL) is also known as the CheckEngine Light.

It can also be warning signs such as:

The “Check engine” control lamp on the control panel will light up (the code will be stored as a fault).
Other related trouble codes may also be present.
Floating revolutions, as well as attempts to stall at idle.
The exhaust gas recirculation system may have other failures due to accumulation of carbon or soot in the system.
The engine may fail the emissions test.
Possible detonation in cylinders.
Reduced engine performance.
Increased fuel consumption.

The severity of code P2413 can range from moderate to severe, depending on the specific symptoms of the fault. As well as the level of performance of the cooler and bypass valve.

A faulty exhaust recirculation valve or control circuit, can cause excessive ignition, as well as early ignition. This can cause damage to pistons, valves, and other related internal engine components.

Factors that can cause this error code

The error code P2413 can mean that one or more of the following problems have occurred:

Dirty or clogged exhaust gas recirculation system.
Faulty EGR valve or temperature sensor.
Excessive soot or carbon buildup on walls.
Short-circuited or broken electrical wiring relating to the EGR system.
Weakened, corroded, or damaged electrical connectors related to the exhaust gas recirculation system.
Exhaust leaks.
Cracked or broken vacuum lines.
Faulty MAP / MAT sensor.
In rare cases, malfunction of engine control module (ECM).

How to fix or reset OBD-2 code P2413

Some suggested steps for troubleshooting and fix the error code P2413:

Connect an OBD-II scanner to the vehicle’s diagnostic connector and read all stored data and error codes.
Clear the error codes from the computer memory and test-drive the vehicle to see if error code P2413 appears again.
If the error code appears again, visually inspect the electrical wires and connectors related to the exhaust gas recirculation system.
If necessary, repair or replace any shorted, broken, damaged, or corroded components.
If the problem persists, check the exhaust recirculation system ducts for blockage.
Check the operation of the exhaust gas recirculation cooling valve.
Measure the circuit voltage with a digital multimeter.
Compare with the value in the manufacturer’s data sheet, and replace the faulty valve if necessary.
If the problem persists, check and replace the engine control module (ECM) if necessary.

Diagnose and repair of problems

The first step in the troubleshooting process for P2413, is to review the Technical Service Bulletins (TSB). For known problems with a particular vehicle.

The advanced diagnostic steps are very vehicle specific. It may require, special equipment and knowledge to accurately perform the steps.

Allow your vehicle’s engine to cool down. In most cases, exhaust gas recirculation systems are very hot. Since they are usually installed directly on the exhaust system. Therefore, if you don’t let the engine cool down, you can get burned.

Visual damage

Locate all of the components associated with the exhaust gas recirculation cooler circuit and examine them for obvious physical damage. Depending on the specific vehicle, this circuit may include several components. Temperature switch, bypass valve, exhaust gas recirculation valve, exhaust gas recirculation cooler and engine control unit.

Perform a thorough visual inspection to check the wiring for obvious defects such as scratches, scuffs, exposed wires or burn spots. Next, check connectors and connections for safety, corrosion, and contact damage.

Be sure to carefully check the integrity of the wire harnesses. They often run along and around the exhaust pipe. Therefore, you need to secure any loose wires. If you find a blown wire, solder it and make sure it is properly insulated. It is possible that this will be the solution to the P2413 malfunction.

Voltage check

When checking the voltage, you need to identify the lack of a power source or ground. This requires checking the continuity of the wiring, connectors, and other components.

Normal resistance readings for wiring and connections should be 0 ohms. The presence of resistance or lack of continuity indicates faulty wiring. Which is open, shorted, or corroded and should be repaired or replaced.

Reference voltages and allowable ranges may vary depending on the specific vehicle and circuit configuration.

If all of the EGR cooling valve control sensor circuits are serviceable. Use an infrared thermometer to check the EGR cooler (valve) inlet and outlet exhaust temperatures. Compare the results with the manufacturer’s specifications and replace defective EGR cooling system components as necessary.
