What P2413 means
P2413 is a broad EGR performance code, and makers fill it in different ways. GM's 2011 6.6 L LGH Duramax uses it for insufficient flow: the air-mass controller deviation must pass a map value of 1.8 to 2.4 g per revolution for 10 s under steady fuelling, rated Type B. GM's 2005 3.5 L L66 gasoline engine compares valve lift instead: under 0.15 mm while more than 1 mm is commanded, below 4000 rpm, sets it after two drive cycles. VW's 2014 2.0 TDI (CJAA) links it to fuel mean-value adaptation, reporting four or more learning points at the ±6 mg per stroke limit. Typical results are higher NOx, a failed emissions test and, on diesels, reduced power. Narrower flow faults are P0401 and P0402, slow response P240F.

- Typical labor1 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2413
- Check engine light
- Reduced power or derate on diesels
- Knocking or pinging under load on gasoline engines
- Failed emissions inspection
Common causes of P2413
- Most likelySoot or carbon restricting the EGR valve or passages
- PossibleEGR valve not reaching commanded lift (actuator or position sensor)
- PossiblePartly blocked EGR cooler
- Less likelyAir-mass or pressure sensor error distorting the flow calculation
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2413 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 13 | The exact fault in that area. |
What to do next
- Note P2413 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2413
What does P2413 mean?
P2413 means "EGR System Performance". P2413 is a broad EGR performance code, and makers fill it in different ways. It is a generic code, so it means the same on every make.
Is it safe to drive with P2413?
Drive gently and only to a workshop. With P2413 the car can go into limp mode (reduced power) to protect itself.
Will P2413 fail an emissions test?
Yes, it can. P2413 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2413 to fix?
Difficulty: medium. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P2413 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
