P2413EGR System Performance

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
  • Needs a drive cycle to confirm a fix
How the car detects it
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 petrol 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.
What you may notice
  • Check engine light
  • Reduced power or derate on diesels
  • Knocking or pinging under load on petrol engines
  • Failed emissions inspection
Likely causes
  • LikelySoot or carbon restricting the EGR valve or passages
  • PossibleEGR valve not reaching commanded lift (actuator or position sensor)
  • PossiblePartly blocked EGR cooler
  • RareAir-mass or pressure sensor error distorting the flow calculation
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
Repair
