P2413 Code: Exhaust Gas Recirculation System Performance

The P2413 code means the EGR system is not doing what the computer expects: it opens the valve and does not see the change in pressure, temperature or flow that it should. Carbon buildup in the valve and passages is the most common cause. Drive with caution if you notice smoke or a loss of power.

What the P2413 code means

The EGR valve sends part of the exhaust gas back into the intake to lower combustion temperature and cut nitrogen oxides. The computer checks that it works by watching how manifold pressure, airflow or temperature change when the valve opens.

The P2413 code is a performance code. The valve may move electrically, but the actual flow is not correct. Carbon in the valve and its passages is the most common cause, especially on diesels that make many short trips.

An EGR valve that sticks open causes smoke, a rough idle and a lack of power. One that will not open is usually not noticeable while driving, but it shows up in the emissions.

P2413 code symptoms

  • Check engine light on.
  • Loss of power or hesitation if the valve is stuck open.
  • Black smoke on diesels.
  • Rough idle.

Likely causes of the P2413 code

  1. Carbon in the valve or the passages. The most frequent cause.
  2. Faulty EGR valve that does not reach the opening the computer asks for.
  3. Clogged EGR cooler on diesels.
  4. Position sensor or differential pressure sensor that reports wrong values.
  5. Vacuum hoses on pneumatic valves.

How to diagnose the P2413 code step by step

  1. Command the valve with the scan tool and compare the requested position with the actual one.
  2. Watch the MAF or MAP sensor when it opens. Fresh air flow should drop or MAP should rise.
  3. Remove and inspect the valve and the opening into the manifold.
  4. Check the EGR cooler on diesel engines.

How to fix the P2413 code

  • Clean the valve and the passages.
  • Replace the valve if it does not move correctly.
  • Clean or replace a clogged cooler.
  • Perform the valve relearn procedure if the manufacturer calls for it.

Technical reference data

  • With the EGR open at idle on a gasoline engine, the engine should shake or stall. That makes a quick test.
  • On diesels, the EGR works mostly at part load.
  • Approximate values only: check the manufacturer data for your vehicle.

Brand-specific notes

If the engine is heavily loaded with carbon, clean the intake manifold as well as the valve, or the code will come back. The P2413 code is much more common on engines that mostly see short trips.

P2413 on Diesel Engines

Very common on diesels from Volkswagen (TDI), Ford (TDCi), Renault (dCi), Nissan, Toyota (D-4D), and Hyundai and Kia (CRDi).

Frequently asked questions about P2413

Can I drive with a P2413 code?
Yes, but with caution if you see smoke or a loss of power. A stuck valve can make the engine run rough.
Can the EGR valve be cleaned?
Yes, and in many cases that is enough. If the engine is heavily loaded with carbon, clean the intake manifold too.
Is it a good idea to disable the EGR?
No. It is illegal in many places, and the computer will log codes anyway. It is better to repair it.
What does the P2413 code mean?
It means the EGR system is not producing the effect the computer expects. The valve may move, but the real flow does not match what was commanded.
How much does it cost to fix P2413?
Roughly $60 to $600. Cleaning is at the low end, and a new valve or cooler costs more.
