P213D EGR Throttle Control Circuit B High

Limp modePossible

P213D is the opposite electrical fault to P213C on EGR throttle B: the drive line carries voltage where the output stage expects ground, or the driver measures excessive current. A wire touching battery positive, a shorted motor winding that pulls too much current, or a mechanically blocked flap that overloads the motor are the usual triggers. The output stage switches off to protect itself, so the flap returns to its spring position and stops regulating. No manufacturer publishes thresholds for P213D; CARB requires output circuits to be checked for faults in both directions. Throttle A reports the same high condition as P2142, while P213A covers an open circuit and P213B a flap that moves but misses its target. Drivers notice the warning lamp, sometimes reduced power.

Likely causes

Drive wire shorted to battery voltage
Shorted turns in the actuator motor causing overcurrent
Flap mechanically blocked, motor overloaded
Faulty output stage in the engine control module

Symptoms

  • Check engine lamp on
  • Reduced power in some operating ranges
  • EGR readiness not completed
