P213BEGR Throttle Control Circuit B Range/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
P213B is the functional check of EGR throttle B rather than an electrical one. The module compares the position it commands with the position the flap actually reaches, or judges whether the feedback is plausible; if the gap persists beyond a set time, P213B is logged. Regulating flaps sit in a stream of recirculated exhaust and crankcase vapour, so soot and oil deposits that make the blade stiff are the usual reason, followed by worn gears or a weak motor. No manufacturer documents P213B publicly; CARB requires output components to be checked for proper function, and EGR control to be monitored for reaching its limits. The same check for flap A is P0488; pure wiring faults on B appear as P213A, P213C or P213D. The driver notices hesitation, smoke or a power limit.
What you may notice
  • Check engine lamp on
  • Hesitation, black smoke or reduced power
  • Clicking or humming from the flap
  • Filter regeneration may be postponed
Likely causes
  • LikelyFlap stiff or stuck from soot and oil deposits
  • PossibleWorn gear train or weak actuator motor
  • PossibleImplausible position feedback from the flap sensor
  • RareOutdated engine software or missing flap adaptation
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
Repair
Medium · Often possible to do yourself.Typical cost: €60 – €700
