The exhaust gas recirculation (EGR) system plays a vital role in emission control. It lowers the temperature at which combustion takes place inside the engine. This reduces the amount of toxic gases generated as byproducts of burning the air-fuel mixture to generate power.
The EGR system takes its cues from the powertrain control module (PCM). If the emission control system isn’t functioning as designed, the PCM will log a P2413 code.
The diagnostic trouble code (DTC) P2413 indicates “Exhaust Gas Recirculation System Performance.”
The EGR system incorporates a valve that regulates the flow of exhaust gases from the engine to the induction system. When it receives the right signal from the PCM, the EGR valve opens. This lets exhaust gases enter the induction system, where the nitrogen oxides undergo burning to help generate more power.
Depending on the manufacturer, some vehicles can have a manifold air pressure (MAP) sensor and manifold air temperature (MAT) sensor. Like the EGR sensor, they also provide the PCM with data on the EGR system’s performance.
When the PCM activates the EGR valve, it checks the readings from the EGR, MAP, or MAT sensor to see how much the valve opens. It will set the generic code P2413 if the sensor doesn’t show the expected degree of change in the valve’s state.
Note: The definition of code P2413 can differ according to the vehicle manufacturer. Check the appropriate repair manual or repair database for the exact code definition.
The P2413 code is a generic code that can be logged by various makes and models. While it can show up in many vehicles, its symptoms and root cause can vary because of different factors. There is no single solution to every instance of a code P2413.
If you aren’t confident about conducting diagnostic tests on your vehicle, it’s a good idea to bring it to a professional mechanic. Otherwise, you can go ahead and diagnose the issue yourself. To help you get started, here’s a video that can give you an idea of what the process might involve:
You’ll need to have both experience in DIY car repair and the right tools to fix the P2413 code. Otherwise, it’s recommended to bring your vehicle to a trusted auto service center.
Are you a DIYer with advanced technical knowledge and hands-on experience who prefers to test and replace your vehicle’s EGR system on your own? You can make your job easier by consulting the relevant repair manual or refer to an online repair database.
